Which figure represents the image of parallelogram lmnp after a reflection across the line y = x? a. figure a b. figure b c. figure c d. figure d not d

A reflection across the line y = x has a rule:

(x,y)→(y,x).

Parallelogram LMNP has vertices L(3,1), M(4,3), N(5,3) and P(4,1).

Then

Points L', M', N' and P' are exactly vertices of figure C.

correct choice is C.

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

51-50
