Which of the following transformations will produce similar figures? Select all that apply. (1/2 x,1/2 y)
(x + 2, y - 5)
(-x, y)
(2x, 4y)

the second and third one because the other two become larger and smaller while the second and third are just moved. I'm not 100% sure tho I haven't done this in years.

the answer is here: : )

:

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
