(g₀f)(x)=g(f(x))
=g(2x-2)
=5(2x-2)^2-3
=5(4x^2-8x+4)-3
=20x^2-40x+17

Answer:
$14
Step-by-step explanation:
Oliver earnings per day = $4
Each day, his mom takes $2 and put it into a savings account for Oliver
His savings per day = $2
Oliver's total savings after 7 days = savings per day × 7 days
= $2 × 7
= $14
Oliver gets to keep a total of $14 after 7 days
(2/5)^3=(2/5)*(2/5)*(2/5).
x/16 = (x-1)/14
14x = 16x-16
2x = 16
x = 8 minutes (Roger time)
Roger will run rt = (1/16)8 = 1/2 mile
x-1 = 7 minutes (Jeff time)
Jeff will run rt = (1/14)7 = 1/2 mile
