Helen is putting up a fence in her backyard. She has a total of 150 feet of fencing to put up and needs to put up a fencing post every 6 1/2 feet. If x represents the number of posts that Helen has to use, write an equation to represent this situation.

x - 1 = 150/6.5    (because 150/6.5 = 23 spaces, it will need an end post.)

23 spaces needs 24 posts

your answer is the last one

step-by-step explanation:

divide the length of a'c' by the length of ac to get a scale factor of two

& then reflect vertically (over the y-axis)

so your answer is dilation by a scale factor of 2 followed by reflection over the y-axis
