Answer:
The correct answer is 28
Step-by-step explanation:
Step-by-step explanation:
4^5 (-2)^9/4^8 (-2)^3
= 4^(5 - 8) (-2^(9 - 3))
= 4^-3 (-2^6)
= (-2)^6/4^3
1). (-2)^a/4^b
a = 6, b = 3
2). c/d
c = -2, d = 4
You can factor out the square root of two from the num and denom of this fraction leaving you with 1/3 or 1.33

so if x = -1, let's plug that in the second equation
-5(-1)+y = 5
5+y = 5
y = 0
