Step-by-step explanation:

divide 8 by 2 to get 4 and multiply 2 times 5 to get 10, then add 10 + 4

If b=5 and a is 1/2 then 5 - 1/2 = 4 1/2

D) EFGH moved onto E'F'G'H after rotating 180 counterclockwise around the origin and the reflecting across the y-axis.

<h3>How to carry out transformations?</h3>
