Answer:
15
Step-by-step explanation:
The general form of an exponential equation is ...
f(x) = (initial value)(growth factor)^x
That is, the "growth factor" is the base of the exponent. In your equation ...
f(x) = (1/5)(15^x)
the growth factor is 15.
15/60 is the Awnser. Cuz 3•5 is 15 and 10•6 is 60
The answers would be -8 and 18
-8×18 = -144
-8+18 = 18-8 = 10
