Y= 4x +3, 4x + y =3 are they parallel or perpendicular
Answer: Neither
Step-by-step explanation:
When two lines are parallel, their slopes are the same.
When two lines are perpendicular, their slopes are opposite reciprocals. Opposite reciprocals equal -1 when multiplied together.
Equation #1: y = 4x + 3
The equation is in the form y = mx + b, so the slope is 4.
Equation #2: 4x + y = 3
We need to put this equation in slope-intercept form.
1) Subtract 4x from both sides
y = -4x + 3
The slope is -4.
-4 and 4 are neither equal nor opposite reciprocals, so they aren't parallel or perpendicular.
The slope of both lines is neither the same nor negative inverse of each other thus both lines will neither parallel nor perpendicular.
What is slope?A slope is a tangent or angle at a point or a slope is the intensity of inclination of any geometrical lines.
Slope = Tanx where x will be the angle from the positive x-axis at that point.
The slope is also calculated by differentiation for example slope of y = sinx will be y' = cosx.
As per the given lines,
y = 4x +3
The slope-intercept form is given as y = mx + c where m is the slope.
By comparing slope m = 4
4x + y =3 → y = -4x + 3
Slope m = -4
Since slopes are not the same thus they will be not parallel.
Perpendicular lines slope's multiplication gives -1.
Since, 4 x (-4) ≠ -1 thus both will be not perpendicular.
Hence "The slope of both lines is neither the same nor negative inverse of each other thus both lines will neither parallel nor perpendicular".

Y = -2(x+4) + 6 when x = -2 then use that value of y to evalute w = -3 - 2y
Answer:
12
Step-by-step explanation:
Plug in for x first:
Y = -2(x+4) +6
Y = -2((-2)+4) +6
Y = -4 + 6
Y = 2
Then use Y to find W;
W = -3 -2y
W = -3 - 2(2)
W = -3(-4)
W= 12
Answer:
y=8 and w=13
Step-by-step explanation:
y=-2(x+4)
-2x-2=4 sooo...
y=4+4
y=8
then plug 8 into the equation for w
w=-3-2y
then you would get
w=-3-16
-3-16
w=13

12. The last option, A=1/4, B=7/16, C=5/8, D=3/4
Step-by-step explanation:
11. look at the denominators, and what do you see? I see that 11 is 88 divided by 8. So, let's divide the numerator by 8 as well! 48/8=6
12. 1/4 is half of 1/2, so it would be between 0 and 1/2, or A
Same thing with 3/4 but this time in the middle of 1/2 and 1, or D
5/8 is a little over 4/8, or 1/2, so C

Line M passes through points (4, 2) and (-7, 1) what is the slope of a line N that is parallel to line M
The solution is :
We conclude that the slope of line 'n' is: m₂ = 10
What is slope?In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).
Given
The slope of line m is: m₁ = 10
It is stated that another line is parallel to line m.
Let m₂ be the slope of the 'n' line.
We know that when two lines are parallel, they have equal slopes.
i.e. m₁ = m₂
as
The slope of line m is: m₁ = 10
and
The lines are parallel
so
The slope of line 'n' is: m₂ = 10
Therefore, we conclude that the slope of line 'n' is: m₂ = 10.

Answer: First, you start with the equation:
9
x
+
4
=
472
Since four students rode in cars, you want to eliminate this part of the problem to find how many students actually rode in the buses
So you would subtract
4
from both sides and get:
9
x
=
468
Finally, you would divide both sides by
9
and get
52

B is between A and C. AB = 5 and AC = 8. What is the length of BC
Answer:
BC = 3
Step-by-step explanation:
If you picture A, B, and C on a line, the first part of the line, AB, has a length of 5 and the total line, AC, has a length of 8 . Means that the second part of the line, BC, has a length of 3 because you would add the length of both the first and second part of the line in order to get the total length of the line.
AB + BC = AC
5 + BC = 8
BC = 3
A line with a slope of -10 passes through the point (1,-10) what is it equation in slope intercept form?
Answer:
y=-10x
Step-by-step explanation:
m=-10
For (1,-10) a=1 AND b=-10
(use the formula y-b=m(x-a) to find the equation of the line)
y-b=m(x-a)
(sub the values of m (the slope) and a&b (from the point)
y - (-10) = (-10) × ( x - 1 )
(simplify)
y+10=-10(x-1)
(expand the bracket)
y+10=-10x+10
(subtract 10 for both sides)
y=-10x+10-10
(simplify)
y=-10x
