Answer:
y= -50x + 400
Step-by-step explanation:
-50 miles from the place which means they are going further and further away so it is negative. And its 400 because y=mx+b the b is 400 because thats where they started. Also it said it was correct on A-p-e-x.
A) (x, y) → (3x, 3y)

Explanation:</h2>
When you dilate an object, you enlarge or reduce the size of it. To do this, we need a scale factor which allows us to make the object larger or smaller depending on the value of that factor. Let's call this factor as k, then it is true that:
- If k > 1, the object will be larger than the original one.
- If k < 1, the object will be smaller than the original one.
If the dilation is performed centered at the origin, then corresponding points of the original and dilated figures will be connected by straight lines, being the center of dilation the point where all the lines meet.
The only option that meets this requirement is:
A) (x, y) → (3x, 3y)
Whose scale factor is k = 3 making the dilated figure larger than the original one.

Answer:
68%
Step-by-step explanation:
Calculate percentage change
from V1 = 82 to V2 = 138
(V2−V1)|V1|×100
=(138−82)|82|×100
=5682×100
=0.682927×100
=68.2927%change
=68.2927%increase
=68%
