Find the inverse function of f(x) . f(x) = 7x - 9

The inverse of this function is f(x) = .

All inverse functions can be found by switching the x and f(x) values. Then you can solve for the new f(x). The result is the inverse function. Below is the step-by-step process for finding one.

f(x) = 7x - 9 ----> Switch the x and f(x)

x = 7f(x) - 9 -----> Add 9 to both sides

x + 9 = 7f(x) ----> Divide both sides by 7

f(x) =

answer: 15

step-by-step explanation:

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
