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

13.57

Step-by-step explanation:

We have been given an equation , 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 .

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

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

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

10d + 9 = 0

Step-by-step explanation:

Simple explanation:

1.  8d + 2d + 6d + 9 - 6d = 0

2. 16d + 9 - 6d = 0

3. Ans: 10d + 9 = 0

Thorough explanation

1. Solve the equation using BIMDAS OR BEDMAS - whatever acronym you were taught

2. Since there are addition and subtraction in this equation we need to solve it from left to right.

3. Re-arrange the equation by putting like terms together - if that makes sense:

So 8d + 2d + 6d + 9 - 6d = 0

Becomes  8d + 2d + 6d - 6d + 9 = 0

4. Then you simply simplify the equation (Remember, go from left to right)

5. (8+2+6)d - 6d + 9 = 0

6. 16d - 6d + 9 = 0

7. (16-6)d + 9 = 0

8. Ans: 10d + 9 = 0

You can leave it at here because you only need to solve the equation. However, if the question says to "solve for d" (which is not the question being asked rn), then take 9 from both sides: 10d + 9 - 9 = 0 - 9

Which gives you: 10d = -9

Then divide by 10

                         10d/10= -9/10

             Ans:            d = -9/10

d would equal negative nine over ten
