HELP ME Write and solve a proportion to find y.

Given:

A figure of dilation and the center of dilation is O.

To find:

The value of y.

Solution:

The distance between center and vertex of image (d') is proportional to the distance between center and the corresponding vertex of original figure (d).

Where, k is the scale factor or constant of proportionality.

So, the scale factor for the given dilation is

We know that,

Divide both sides by 9.

Therefore, the value of y is 12.

18a

step-by-step explanation:

simply because it is. it's the highest common factor
