What is the v-value of the vertex?
f(x) = (x + 2)^2 - 1
-value of the vertex:

Okay, I don't know what a V-value is, but I can get the vertex coordinates...

Step-by-step explanation:

So, this is the basic formula for parabolas:

Now, your equation is this form, and the vertex of parabola's in this context is:

So, therefore:

Hopefully this is a good explanation!

2,600 divided by 80 = 32.5

step-by-step explanation:

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,
