F(x) = x^2 - 3x
f(-8) = (-8)^2 - 3(-8)
f(-8) = 16 - (-24)
f(-8) = 16 + 24
f(-8) = 40 (Answer)

Your car gets 15 miles to the gallon and your friend's car gets 25 miles to the gallon. you decide to go on a road trip to virgi
sergij07 [2.7K]

You would save $32 if you used your friends car.

I found this out by doing this:

300/15 will tell you how many gallons of gas it would take to get to Virginia Tech in your car(20 gallons). You would then multiply that by the price of gas($4), which would = $80.

300/25 will tell you how many gallons of gas it would take to get to Virginia Tech in your friends car(12 gallons). You would then multiply that by the price of gas($4), which would = $48.

So to come up with the difference you would do $80-$48, which is $32.

I hope this helped Tinytoonjr6552!
