To find the number of cars that will drive by in 7 minutes, we need to substitute x=7 into the function f(x)= 12x + 3.
f(7) = 12(7) + 3 = 84 + 3 = 87
Therefore, 87 cars will drive by in 7 minutes.
Suppose that the function f(x)= 12x + 3 represents the number of cars that drive by in x minutes. How many cars will drive by in 7 minutes?(1 point)
