40 can be gotten by multiplying 10 & 4

28 can be found by adding 10 + 10 + 4 + 4

so the side lengths are 4 & 10

Mr. Tolin purchased a used car for $2,816, which was 12% off the asking price. What was the asking price of the used car?

Nina [5.8K]

Answer:

Original price= $3,200

Step-by-step explanation:

Giving the following information:

Purchase price= $2,816

Discount rate= 12% = 0.12

To calculate the original price, we need to use the following formula:

Original price= purchase price / (1 - discount rate)

Original price= 2,816 / 0.88

Original price= $3,200

What is the slope of the line that passes through the points (-4, -2)(−4,−2) and (-4, -22) ?(−4,−22)? Write your answer in simpl

Anestetic [448]

The line is vertical, so the slope is infinite

Step-by-step explanation:

Given two points with coordinates $(x_1, y_1)$ and $(x_2,y_2)$ , the slope of the line passing through the two points is given by the equation

$m=\frac{y_2-y_1}{x_2-x_1}$

In this problem, the coordinates of the two points are:

$(x_1,y_1)=(-4,-2)$

and

$(x_2,y_2)=(-4,-22)$

which means:

$x_1=-4\\y_1=-2\\x_2=-4\\y_2=-22$

Substituting all these values into the equation of m, we find the slope of the line:

$m=\frac{-22-(-2)}{-4-(-4)}=\frac{-20}{0}=\infty$

The slope is infinite: this is because the line is vertical.

Which equation would graph as a straight line? x2 – y = 0 y = x 2y = x2 y=1/2×2-1 x2 = 0

Gwar [14]

Answer:

y=1/2×2-1

Step-by-step explanation:

x2 – y = 0 yields a parabola.

y = x is straight but has a slope to make it increase/decrease.

2y = x2 yields a parabola.

x2 = 0 yields a parabola.
