Answer:
a = 9, b = 3, c = 0
Step-by-step explanation:
f(x) = (1/3)^x
a = f(-2) = (1/3)^-2= 9
b = f(-1) = (1/3)^-1 = 3
c = f(0) = (1/3)^0 = 1
whenever something is to the power of 0, the answer will always be 1
Answer:
x=-2, y=8. (-2, 8).
Step-by-step explanation:
8x+5y=24
y=-4x
----------------
8x+5(-4x)=24
8x-20x=24
-12x=24
x=24/-12
x=-2
y=-4(-2)=8
