Question

Answer 1

Choices

Answer 2

its the 3rd choice

an easy way to do this is by substitution

substitute x = 1 into each equation and evaluate

y = 1^8 so y = 1

y = 8^1 so y = 8

y =(1 +8)^2 so y = 9^2 or 81

y = 8(1) so y = 8

then check the 3rd option works with x = 2

if so thats the answer.
