Identify the initial amount a and the decay factor b in each exponential decay or neither. Y= 8x0.8^x
f(x)= 12x0.1^x

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5

step-by-step explanation: the answer is 27. first multiply .32 by 25 which equals 8. then add 8 to 25 which gives you 33. then you subtract that from 6 since she gave 6 to her brother.

,, add !

7.25
