brilliants [131]

Answer:

  f^-1(x) = x +6

Step-by-step explanation:

To find the inverse of the function

  y = f(x)

solve the equation

  x = f(y)

for y.

Here, you want ...

  x = f(y)

  x = (y -6)

  x +6 = y . . . . . . add 6 to both sides

  \boxed{f^{-1}(x)=x+6}\\

You have recorded your car mileage and gasoline use for 5 weeks. Estimate the number of miles you can drive on a full 15-gallon
I am Lyosha [343]

Answer:

325 miles to the nearest mile.

Step-by-step explanation:

Average  gasoline consumption over the 5 weeks

= miles travelled / gasoline used

= (198 + 115 + 154 + 160 + 132) / (9 + 5 + 7 + 8 + 6)

= 21.69 miles per gallon.

Estimate of number of miles you can drive on 15 gallons

= 15 * 21.69

= 325 miles.
