Which transformation would result in the area of a polygon being different from the area of its pre-image a) (x, y) (-x,-y) b) (x, y) (-y,-x) c) (x, y) (x+h, y+k), where h and k are real numbers d) (x, y) (kx, ky), where k doesn't equal 1

D

because

A and B merely reflects the polygon on the graph

C merely translates the polygon

To cause a different area a graph usually must have a stretch or shrink and is indicated by multiplying either the x or y value. In this case both the x and y are being multiplied.

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )
