Answer:

C) $y - 20 = 2(x - 80)$

Step-by-step explanation:

According to the Point-Slope Formula, $y - y_1 = m(x - x_1)$ , all the negative symbols give you the OPPOSITE terms of what they really are, so be EXTREMELY CAREFUL inserting the coordinates into the formula with their CORRECT signs.

I am joyous to assist you anytime.

Autumn bought 4 pairs of jeans for her kids and one shirt for herself. The shirt cost $16.99. She spent a total of $108.95. What

klio [65]

Answer:

Each Jean cost $22.99

Step-by-step explanation:

First you would subtract the cost of the shirt from the total.

108.95-16.99=91.96

Then you would divide the 91.96 by 4 to get the cost for each Jean.

91.96/4=22.99

j=$22.99

How to find the diameter of a circle with the area of 1134.1?

Alex17521 [72]

Radius is half of the diameter.
So because the area of a circle is A= pi • r^2, to find the radius first, we have to change the equation to solve for r. Now it is, r= square root of A/pi. We plug in 1134.1. (Look at pic)
The diameter is 38

Circle X with a radius of 6 units and circle Y with a radius

asambeis [7]

Answer:

Option C.

Step-by-step explanation:

It is given that radius of circle X is 6 units and radius of circle Y is 2 units.

Here, circle Y is smaller and circle X is larger.

$\text{Scale factor}=\dfrac{\text{Radius of circle X}}{\text{Radius of circle Y}}$

$\text{Scale factor}=\dfrac{6}{2}$

$\text{Scale factor}=3$

If we translate the circles so they share a common center point, and after that we dilate circle Y by a scale factor of 3, then we get circle which is equal to circle X.

We know that, after dilation the figure and its image are similar.

Hence, we can say that both circles are similar.

Therefore, the correct option is C.
