Answer:
y=-x,A
Step-by-step explanation:
When we input -5 in for x, we get 5
When we input 7 in for x, we get -7
(2/3)^2⋅(2/3)^6 = (2/3)^(2+6) = (2/3)^8
When we have the same thing being multiplied by itself with a different exponent on it, we add the two exponents.
(a^b)*(a^c) = a^(b+c)
0.0625 that is the answer
