How did they get the vertex i need assistance

Step-by-step explanation:

The general formula of a quadratic equation is

while the general formula for finding the vertex is

first of all, you have to set the value of

From the given equation, a = 2; b = -12 and c = 13. therefore, x = -(-12)/2(2) = 12/4 = 3

The 3 gotten is the answer for the value of h. To get k, substitute the value of h into the quadratic equation.

k = 2(3)^2 - 12(3) + 13 = -5

Therefore, the Vertex is V(h,k) = V(3,-5)

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,
