Answer:

A. 3/2

Explanation:

What is dilation?

The original image is DEFG. It is called the pre-image

The dilated image is D'E'F'G' and is called image

A transformed image has the coordinates labeled with a '

In this case the transformed image is a dilation of the original pre-image. A dilated image is a cop.y of the pre-image but with either an expansion or a compression

If the image is larger than the pre-image it is an expansion, if smaller than the pre-image then it is a compression

With dilation, comes a scale factor which indicates how much a pre-image has been expanded or compressed

Solution

If you look at the two images, take any side in the pre-image and compare its length with the corresponding side you can find the scale factor

Here if you take a side, say DE = 4 and look at the corresponding side D'E' = 6you see that the DE side has been expanded with a scale factor of 6/4 = 3/2

This scale factor applies to all sides, so you need to take only one side to find the scale factor

Answer: Scale Factor of dilation = 3/2

This is option A

Answer:

A. 3/2

Explanation:

what is a dilation? a dilation can make objects bigger or smaller.

10 times
(3)/(2) is 15

4 times
(3)/(2) is 6

8 times
(3)/(2) is 12

therefore the answer is A..
(3)/(2)
