A car dealership sells used cars for $7,000 and new cars for $16,000. If a total of 17 cars were sold for $191,000, how many of

Ipatiy [6.2K]

Let u be the number of used cars and n the number of new cars, then u+n=17.
Sales values: 7000u+16000n=191000; so 7u+16n=191.
Since n=17-u, we can rewrite this: 7u+16(17-u)=191.
7u+272-16u=191, 9u=272-191=81 and u=9. So 9 used cars were sold (8 new).

What is the inverse of the function below? f(x) = 5x - 2

kupik [55]

Answer:

B. f -1(x) = x + 2 / 5

$f^{-1}(x)=\frac{x+2}{5}$

Step-by-step explanation:

To find the inverse of a function we need to interchange x and y an solve for y.

Since $f(x)=y$ , then

$f(x)=5x-2$

$y=5x-2$

$x=5y-2$

Add 2 to both sides

$x+2=5y-2+2$

$x+2=5y$

Divide both sides by 5

$\frac{x+2}{5}=\frac{5y}{5}$

$\frac{x+2}{5}=y$

$y=\frac{x+2}{5}$

$f^{-1}(x)=\frac{x+2}{5}$

We can conclude that the correct answer is B. f -1(x) = x + 2 / 5
