Write y = x2 - 4x + 6 in vertex form.

y = (x-2)²  + 2

Step-by-step explanation:

Converting  y = x² - 4x + 6 in vertex form simply means converting from standard form y =  ax² - bx + c to the vertex form y = a(x-h)² + k

To start always check and make sure your a=1

In this equation our a=1

Next  is to find (b/2)²

(b/2)²  =  (-4/2)²  = (-2)²  = 4

Now we want to create a perfect square in our given equation, to do that we will add  the value of (b/2)² which is equal to 4 to the linear and quadratic term. That is;

y = x² - 4x + 6

y =( x² - 4x + 4) + 6

Since we added 4 into the parenthesis, we will subtract 4 outside the parenthesis to normalize the equation

y = (x² - 4x + 4) + 6 -4

We now have y = (x² - 4x + 4)  + 2  (1)

In the parenthesis we have: x² - 4x + 4 and this is a perfect square, think of the square that will give you this result, and that square is (x-2)²

We will now replace  x² - 4x + 4  by (x-2)²  in equation (1)

y = (x-2)²  + 2

Therefore  y = x2 - 4x + 6 in vertex form is y = (x-2)² + 2

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,

hope it

answer: 94

step-by-step explanation: 79+91+92+94+94 = 450 divided by 5 (since there are 5 number that are being added) = 90
