Question

Determine the n-intercept of the graph of the graph of the car value equation v= -1385n + 18,790

Answer 1

-1385N + 18,790  = 0
n  = -18790  / -1385 =  13.57 to nearest hundredth

Answer 2

Answer:

13.57

Step-by-step explanation:

We have been given an equation $v=-1385n+18,790$, which represents the value of a car. We are asked to find the n-intercept of our given equation.

We know that the n-intercept will be at $v=0$.

$0=-1385n+18,790$

Subtracting 18,790 from both sides of our equation we will get,

$0-18,790=-1385n+18,790-18,790$

$-18,790=-1385n$

Now, we will divide both sides of our equation by $-1385$.

$\frac{-18,790}{-1385}=\frac{-1385n}{-1385}$

$13.566787=n$

$n\approx 13.57$

Therefore, the n-intercept of our given graph is approximately 13.57.
