We are asked to find z = g0f or what is the same:
 z = g (f (x))
 That is, we must introduce the function f (x) within the function g (x)
 So, we have
 f (x) = 3x-9
 g (x) = x ²
 Therefore we have the following function
 z = (3x-9) ²
 Finally (g0f) (5) = (3 (5) -9) ²
 (g0f) (5) = 36

Gala2k [10]
Since he bought 2 model cars for $8.95 each, he bought both for $17.90. Now, subtract this from the total cost to get the cost of paint. $23.65-$17.90=$5.75. So, the total costs of paints are $5.75. Hope this helped!

Reuben drove 268 miles using 12 gallons of gas. At this rate, how many miles would he drive using 9 gallons of gas?
Sav [38]

This question calls for ratios. Reuben drove 268 miles with 12 gallons. 268 divided by 12 is 22\frac{1}{3}, so he can drive 22 and one third of a mile with one gallon. Multiply that by 9 and you will get 201 miles, which is how much he can drive using 9 gallons of gas
