Answer:
f^-1(x) = (x+20) / 12
Step-by-step explanation:
f(x) = 4(3x-5)
Let y be the image of f.
y = 4(3x-5)
y = 12x-20
y+20 = 12x
x = (y+20) / 12
f^-1(y) = (y+20) / 12, so
f^-1(x) = (x+20) / 12
Answer:
3.4 Hours
Step-by-step explanation:
25 x $7.75 = $193.75
$250 - $193.75 = $21.25
$21.25/$6.25 = 3.4 hours
You must work 3.4 hours at the second job.
