Answer:
72%
Step-by-step explanation:
Turn the denominator to 100.
So: 18/25 times 4 equals 72/100
72/100= 72%
*You turn the denominator into 100 because all percents are out of 100.*
Enter the slope-intercept equation for the image of line ℓ after a clockwise rotation of 90°. (Hint: To find the image of line ℓ, choose two or more points on the line and find the images of the points.)
Answer:
[tex]y=\frac{1}{7}x-\frac{6}{7}[/tex]
Step-by-step explanation:
Two points (1, -1) and (0, 6) are lying on the given line.
Rule to find the coordinates of a point by the rotation of 90° clockwise is,
(x, y) → (y, -x)
Therefore, image points of (1, -1) and (0, 6) will be,
(1, -1) → (-1, -1)
(0, 6) → (6, 0)
Slope of the line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Therefore, slope of the line passing through (-1, -1) and (6, 0) will be,
m = [tex]\frac{0+1}{6+1}[/tex] = [tex]\frac{1}{7}[/tex]
Equation of the line passing through (6, 0) and slope = [tex]\frac{1}{7}[/tex]
y - y' = m(x - x')
y - 0 = [tex]\frac{1}{7}(x - 6)[/tex]
[tex]y=\frac{1}{7}x-\frac{6}{7}[/tex]

Which table represents a linear function?
pls answer quick :)
Answer:
The first table
Step-by-step explanation:
A linear function is represented when x and y are increased at a constant rate. In the first table, you can see that as x increases by 1, y increases by 1/2, thus the first table is a linar function.
how do you know if an ordered pair output is a function?
Answer:
If there is more than one X value in the ordered pairs and they have different Y values, it is not a function. Otherwise, it is a functio
Answer:
You could set up the relation as a table of ordered pairs. Then, test to see if each element in the domain is matched with exactly one element in the range. If so, you have a function!

Triangle ABC is transformed to triangle A′B′C′, as shown below:
A coordinate grid is shown from negative 4 to 0 to 4 on both x- and y-axes. A triangle ABC has A at ordered pair negative 1, 3, B at ordered pair 0, 1, C at ordered pair negative 3, 0. A triangle A prime B prime C prime has A prime at ordered pair negative 1, negative 3, B prime at ordered pair 0, negative 1, C prime at ordered pair negative 3, 0.
Which equation shows the correct relationship between the measures of the angles of the two triangles?
The measure of angle CAB = The measure of angle C prime B prime A prime
The measure of angle BCA = The measure of angle A prime B prime C
The measure of angle CAB = The measure of angle C prime A prime B prime
The measure of angle BCA = The measure of angle C prime A prime B prime low
Answer:
The measure of angle BCA = The measure of angle A prime B prime C

3. A Fahrenheit thermometer reads 63°F. If the temperature increases 10°F, to the nearest degree, what is the new temperature C, in degrees Celsius?
Formula to convert F to C:
(F -32) x 5/9
F = 63 + 10 = 73
73-32 = 41
41 x 5/9 = 22.77777
Rounded to the nearest degree = 23 C
Answer: 63 +10 =73 then you have to round it right
it would be 70 degrees Celsius
Step-by-step explanation:
it would be rounded to 70 because 73 cant be round to 80 the 3 is ot higher than 5
Ryan is three years younger than twice his brother’s age. Ryan is eleven.
Which equation will help us find his brother’s age?
2 b + 3 = 11
2 b – 3 = 11
b/2 – 3 = 11
b/2 + 3 = 11
Answer:
2b - 3 = 11
Step-by-step explanation:
7 × 2 is 14 and 14 minus 3 is 11 Ryan's brother is 7
Which of the sets of ordered pairs represents a function?
A = {(2,-2), (5,-5), (-2, 2), (-5,5)}
B = {(4,2), (4,−2), (9, 3), (9, −3)}
Select the interval where f is negative
Answer:
The negative regions of a function are those intervals where the function is below the x-axis. It is where the y-values are negative (not zero). y-values that are on the x-axis are neither positive nor negative. The x-axis is where y = 0.

AM I CORRECT DO I NEED TO ADD AN ANSWER OR TAKE AWAY ONE
You should take off E and add C and D because perpenidcular bisector means not only does it form a right angle to the line, it also bisects it, or cuts it into 2 equal portions. Also, If you look at triangles BED and BEF, they are congruent as both have right angles and equal sides BE, and DE = EF. So, BD = BF.
E is wrong because you don't know if line AC is perpendicular to DA, nor do you know if it's parallel to DF. And you don't know if DA is parallel to BE either. You ONLY know that BE is the perpendicular bisector of DF.

factor 2x^2 - 7x = 0
Answer: x=3.500
Step-by-step explanation: product of several terms equals zero.
When a product of two or more terms equals zero, then at least one of the terms must be zero.
We shall now solve each term = 0 separately
In other words, we are going to solve as many equations as there are terms in the product
Any solution of term = 0 solves product = 0 as well.
2x-7 = 0
Add 7 to both sides of the equation :
2x = 7
Divide both sides of the equation by 2:
x = 7/2 = 3.500

Dawn and Mary work at Great Clips. They each make $11.50 per hour plus tips. Last weekend, Dawn worked x number of hours and earned $125 in tips. Mary worked y number of hours and earned $153 in tips. Dawn determined that using the expression 11.50x + 125 + 11.50y + 153 will calculate the amount the girls earned together last weekend. Select another expression the girls could use.Immersive Reader
Answer:
T=11.50(x +y) + 278Step-by-step explanation:
in this problem we are looking at an alternative expression to the given expression for the total earning which is
Given data
T=11.50x + 125 + 11.50y + 153
let us collect like terms we have
T=11.50x + 11.50y + 153+ 125
T=11.50x + 11.50y +278
we can factor out 11.5 since it is common
T=11.50(x +y) + 278
The alternative expression the girls could use is
T=11.50(x +y) + 278

Answer:
33
Step-by-step explanation:
Answer:
f(5) = 33
Step-by-step explanation:
Just plug 5 into x
f(x) = 9x - 12
f(5) = 9(5) - 12 = 45 - 12 = 33
