Question

The ordered pair (2, 36) is a solution for which equation(s)? Check all that apply.

A. y = (x + 4)2
B. y = 7x2 + 2
C. y = (3x)2
D. y = 2x2

Answer 1

plug it into each equation and see if both sides are equal:
A. 36 = (2+4)^2 -> 36 = 36 works
B. 36 = 7(2)^2 +2 -> 36 = 30 doesn't work
C. 36 = (3(2))^2 -> 36 = 36 works
D. 36 = 2(2)^2 -> 36 = 8 doesn't work
