Slope: slope-intercept form, point-slope form, or slope formX-intercept: intercept form, standard formY-intercept: slope-intercept form, intercept formStep-by-step explanation:
You want to know how the form of a linear equation can be used to reveal its key characteristics.
Key CharacteristicsThe characteristics of a linear equation that are of interest for this problem are ...
slopex-intercepty-interceptForms of a linear equationA linear equation can be written in many forms. Some of these forms make it easy to determine one or more of the key characteristic listed above. Some of the more common forms are Slope-Intercept form, Point-Slope form, and Standard form. There are a number of others.
Slope-Intercept formThe slope-intercept form is ...
y = mx + b
where m is the slope, and b is the y-intercept. This form makes it easy to determine ...
slopey-interceptThis equation cannot be used to describe a vertical line.
Alternate Slope-Intercept formWe can rearrange the above equation to reveal the x-intercept.
y = m(x -a)
where m is the slope and 'a' is the x-intercept. This form makes it easy to determine ...
slopex-interceptThis equation cannot be used to describe a horizontal line (except y=0).
Point-Slope formThe equation of a line with slope m through point (h, k) can be written as ...
y -k = m(x -h)
This makes it easy to determine ...
slopea point on the line (not necessarily an intercept)This equation cannot be used to describe a vertical line.
Standard formThe standard form equation of a line is similar in style to the standard form equations for other geometric figures (circle, ellipse, hyperbola). This form is ...
Ax +By = C
where A, B, C are mutually prime (integers), and A ≥ 0. If A = 0, then B > 0. That is, the leading coefficient is positive. Integers are preferred for the coefficients, but some lines have irrational slope or other key characteristics, so integers may not be able to be used in all places.
The key characteristics cannot be read from the equation directly, but they are one step away:
slope = -A/Bx-intercept = C/Ay-intercept = C/BSolving for the intercepts is especially easy, so we list this form as one that can be efficient for determining the intercepts.
Intercept formA very nice form for efficiently determining the intercepts, or efficiently writing an equation from the intercepts is ...
x/a +y/b = 1
where 'a' is the x-intercept, and 'b' is the y-intercept. This form makes it very easy to determine ...
x-intercepty-interceptYou may notice that dividing the standard form equation by C and rearranging the coefficients will give you this form:
Ax +By = C
(A/C)x +(B/C)y = 1 . . . . . . . divide by C
x/(C/A) +y/(C/B) = 1 . . . . . . . intercept form
General formThe general form of a polynomial equation of any degree is ...
f(x, y) = 0
The general form of a linear equation is ...
Ax +By +C = 0
This is simply a rearrangement of the Standard form equation. Equations written in this form can be helpful for ...
finding the distance from a point to the linesolving a system of equations by "addition" or matrix methodsVarious 2-Point formsWhen two points are given, and you want an equation of the line, various forms are available for using those coordinates. These forms make use of the fact that the slope of a line is the same everywhere, so the ratio of any difference of y-coordinates to the corresponding difference of x-coordinates is a constant (the slope). Again, slopes of 0 or "undefined" can cause trouble with certain of these forms. Here are several different arrangements of 2-point forms:
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)\\\\(x_2-x_1)(y-y_1)=(y_2-y_1)(x-x_1)\\\\\dfrac{y-y_1}{x-x_1}=\dfrac{y_2-y_1}{x_2-x_1}=m\qquad\text{Slope form}\\\\\\\dfrac{x-x_1}{y-y_1}=\dfrac{x_2-x_1}{y_2-y_1}\qquad\text{inverted from the above}\\\\\\\dfrac{y-y_1}{y_2-y_1}=\dfrac{x-x_1}{x_2-x_1}[/tex]
The last three "ratio forms" are variations of each other. Any such proportion can be written 4 ways. (3 are shown) The form not shown has the variables in the denominator, which is usually not useful.
All of these forms can be written in a "general form" by subtracting one side.
The slope can be read directly from the 1st and 3rd of the forms shown here. It is m = (y2-y1)/(x2-x1).
The slope form is useful for determining ...
slopeDeterminant formAnother 2-point form is one written as a determinant:
[tex]\left|\begin{array}{cc}x-x_1&x_2-x_1\\y-y_1&y_2-y_1\end{array}\right|=0[/tex]

Additional comment
It can be useful to recognize the various forms and their relationship to known points on the line or other key characteristics of the function. Any of the slope or point-slope forms make it easy to write the equations of parallel or perpendicular lines through a given point. (The standard and general forms can be used for this, too.)

(Use your calculator to evaluate the integral correct to four significant digits.) in.
To manufacture a panels that are u = 48 in. wide and 2 in. thick with the profile of the roofing takes the shape of a sine wave with equation y = sin(pi x/12) from flat sheet, the width of the flat sheet would be 49.59in.
Therefore the answer is 49.59
To find the arc length of a continuous function, you need to first define the function and the interval over which you want to find the arc length. Then you can use the following formula:
Arc Length = ∫√(1+(f'(x))^2) dx
Here, f(x) is the function and the interval is [a, b].
The width, w of the flat metal sheet needed to make the panel is the arc length of the sine curve from x = 0 to x = 48in
In this case, f(x) = sin(pi x/12), so the derivative of f(x) is
f'(x) = (pi/12)cos(pi x/12)
Arc Length = ∫√(1+((pi/12)cos(pi x/12))^2) dx from x=0 to x=48
Arc Length ≈ 49.59 in

Can SAS be proven congruent?
Yes , SAS (Side-Angle-Side) is a second Congruence postulate to prove triangle congruence by showing that two sides and their included angles are congruent.
What is SAS Congruence rule?Side-Angle-Side is the rule used to prove whether a given set of triangles are congruent. The SAS rule states: Triangles are congruent if two sides and an included angle of a triangle are equal to two sides and an included angle of another triangle. An included angle is the angle formed by two given sides.. For example : let's us consider two triangles ∆SQR and ∆TSR ,
In above given figure, sides
RS = RS ( common side)
QS = ST ( S divides QT in two equal parts) and angle between QS and SR equal to angle between SR and ST i.e. ∠QSR = ∠RST = 90° (right angle ) and it is included angle . So, by SAS Congruence rule, both of triangles are congruent. Hence, Δ ABC ≅ Δ PQR.

A line u passing through the point (-8, -2) is perpendicular to the line y that cu
the x-axis at x = 5 and y-axis at y = -4. Find the equation of the line u.
Answer:
y = - 5/4x -12
Step-by-step explanation:
Original slope= (0- -4)/(5-0)=4/5
slope of perpendicular line of original = -5/4
so the line passes through the point (-8,-2)
(y - -2) = -5/4 (x - -8)
y + 2 = -5/4x - 10
y = - 5/4x -12
The equation of line u passing through the point (-8, -2) and which is perpendicular to the line y that cut the x-axis at x = 5 and y-axis at y = -4 is 5x + 4y + 18 = 0
Given that line, u passes through (-8,-2) and is perpendicular to line y
line y cut x-axis at x=5 and y-axis at y=-4
that is the point of intercept are : (x1, y1) = (5,0) and (x2, y2) = (0, -4)
Now, the equation of line = (y - y1) = m1*(x - x1)
Here m is the slope of line y
m1 = (y1 - y2)/(x1 - x2)
On solving,
m1 = (0 - (-4))/(5 - 0) = 4/5
We know that when two equations are perpendicular then the multiplication of their slopes = -1
m1 * m2 = -1
Now, m2 = -1/m1 = -5/4
Equation of line u passing through the point (-8, -2) and perpendicular to the line = (y - y1) = m2*(x - x1) => (y - (-2)) = -5/4*(x - (-8)
5x + 4y + 18 = 0

Express x^2 - 5x + 8 in the form of (x - a)^2 + b where a and b are too heavy fractions
Answer:
To express the quadratic expression x^2 - 5x + 8 in the form of (x - a)^2 + b, we need to complete the square. To do this, we can add and subtract the square of half the coefficient of the x term. In this case, that would be (1/2)(-5) = -5/2. Therefore, we add and subtract (1/2)(-5)^2 = (-5/2)^2 = 25/4 to get:
x^2 - 5x + 8 = (x^2 - 5x + (25/4)) + (8 - (25/4))
Next, we need to add and subtract 25/4 in such a way that we can factor the quadratic expression as the square of a binomial. To do this, we add 25/4 to the first term and subtract 25/4 from the second term to get:
x^2 - 5x + (25/4) + (8 - (25/4)) = (x^2 - 5x + 25/4) + (8 - 25/4)
Now we can factor the quadratic expression as the square of a binomial:
(x^2 - 5x + 25/4) + (8 - 25/4) = (x - 5/2)^2 + (8 - 25/4)
Therefore, we can express x^2 - 5x + 8 in the form of (x - a)^2 + b where a is -5/2 and b is 8 - 25/4.
Note that the values of a and b are not whole numbers because we added and subtracted a fraction when completing the square.

For linear function `f`,`f(2)=0` and `f(4)=-6`. Write function `f` in slope-intercept form.
Answer:
y = -3x + 6
Step-by-step explanation:
According to the information given, your two points are (2, 0) and (4, -6).
First you want to find the slope of the line that passes through these points. To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)
Plug in these values:
(-6 - 0) / (4 - 2)
Simplify the parentheses.
= (-6) / (2)
Simplify the fraction.
-6/2
= -3
This is your slope. Plug this value into the standard slope-intercept equation of y = mx + b.
y = -3x + b
To find b, we want to plug in a value that we know is on this line: in this case, I will use the second point (4, -6). Plug in the x and y values into the x and y of the standard equation.
-6 = -3(4) + b
To find b, multiply the slope and the input of x(4)
-6 = -12 + b
Now, add 12 to both sides to isolate b.
6 = b
Plug this into your standard equation.
y = -3x + 6
This is your equation.
Check this by plugging in the other point you have not checked yet (2, 0).
y = -3x + 6
0 = -3(2) + 6
0 = -6 + 6
0 = 0
Your equation is correct.

In the given question, A − B = (−51.4m)x, C =(62.2m)x, and A +B +C =(13.8m)x.
Find the vector A. Find the vector B.
We may disregard the vector x and treat the issue as an arithmetic one since all of the measurements are in the same direction (simultaneous equations).
A − B = −51.4.............................(1)
C = 62.2.............................(2)
A + B + C = 13.8.............................(3)
Now putting the value of C from Equation (2) in Equation (3)
A + B + C = 13.8
A + B + 62.2 = 13.8
Subtract 62.2 on both side, we get
A + B = 13.8 - 62.2
A + B = - 48.4.....................(4)
Adding the equation (1) and (4), we get
2A = - 99.8
Divide by 2 on both side, we get
A = - 49.9
Now subtracting the equation (1) and (4), we get
2B = -48.4 - ( -51.4)
2B = 3
Divide by 2 on both side, we get
B = 1.5
Since all of the calculations are done in terms of the unit vector x.
So the answer is vector B = (1.5m) x and vector A = (49.9m) x.

If two sprouts are selected at random, what is the probability that both will bloom, under the best conditions? 16 percent 24 percent 40 percent 80 percent.
The probability of both sprouts blooming under the best conditions is 16 percent.
The probability that two sprouts will both bloom under the best conditions can be calculated using the formula P(A and B) = P(A) * P(B), where P(A) and P(B) are the probabilities of each sprout blooming. Assuming that each sprout has an independent probability of blooming of 0.5, then the probability of both sprouts blooming is 0.5 * 0.5 = 0.25, or 25%. This can also be expressed as a proportion of 1/4, or a percentage of 25%.
In other words, if two sprouts are selected at random, then the probability that both will bloom, under the best conditions, is 25%. This can also be expressed as a probability of 1 in 4, or 16%. This means that out of 4 sprouts, on average, one will bloom, and the other three will not. Therefore, the probability of both sprouts blooming under the best conditions is 16 percent.

What are transformations?Two-dimensional figures can be transformed mathematically in order to travel about a plane or coordinate system.
Dilation: The preimage is scaled up or down to create the image.
Reflection: The picture is a preimage that has been reversed.
Rotation: Around a given point, the preimage is rotated to create the final image.
Translation: The image is translated and moved a fixed amount from the preimage.
The preimage of the given line has points(x, y), B(2, 3) and C(1, 6).
Now, The graph has been translated down 2 units and reflected 180° along the x-axis so the image of the graph has points(y, - x) B'(3, - 2) and C'(6, - 1).
