Gavin was thinking of a number. Gavin doubles it and adds 6.6 to get an answer of 9. Form an equation with x
from the information.

Given the equation f(x)=a(b)x where the initial value is 40 and the growth rate is 20% what is f(4)

9/10 divide by -3/15 as a mixed number

Hell . what are the solutions to `10x^2 - 38x - 8 = 0`? is this when i find the factors and use the numbers within the factors to determine the zeros? i hope that made sense lol
