What is the inverse of function f? f(x)=10/9r+11

Mathematics
1 answer:
Rasek [7]3 years ago
3 0

f(x) = \frac{10}{9}x + 11 \\

So :

y =  \frac{10}{9}x + 11 \\

Subtract the sides of the equation minus 11

y - 11 =  \frac{10}{9}x \\

Multiply the sides of the equation by 9

9(y - 11) = 10x

9y - 99 = 10x

Divided the sides of the equation by 10

\frac{9y - 99}{10} = x \\

So :

{f}^{ - 1}(x) =  \frac{9x - 99}{10} \\

Karl drove 617.3 miles. For each gallon of gas, the car can travel 41 miles. Select a reasonable estimate of the number of gallo
Hatshy [7]

Answer:

The number of gallons of gas Karl used is 15 gallons.

Option (C) is correct.

Step-by-step explanation:

As given

Karl drove 617.3 miles.

For each gallon of gas, the car can travel 41 miles.

i.e

1 gallons = 41 miles

1\ miles = \frac{1}{41}\ gallons

Now find out for the  617.3 miles.

Thus

617.3\ miles = \frac{617.3}{41}\ gallons

617.3\ miles = 15.1\ gallons

617.3\ miles = 15\ gallons\ (Approx)

Therefore the number of gallons of gas Karl used is 15 gallons.

Option (C) is correct.
