Y = -10 and x = -13 (substitute 2y + 7 for x)
Answer:
A.
Step-by-step explanation:
for (10,5)
5 - 5 = 2(10 - 10) = 0
for (4,-7)
-7 - 5 = 2(4 - 10) = -12
Power of a power as applied to exponents is the following:
The power of a power is the product of the exponents, or
(x^a)^b = x^(ab)
For example
(5^2)^3=5^(2*3)=5^6=15625
