Answer:
y = (x + 4.5)² - 13.25
Step-by-step explanation:
y = x² + 9x + 7
We need to get a perfectly squared binomial as part of the right side.
Take the '9x' term, divide it in half, square it, add <u>and also subtract it </u>on the right side, as shown below. That would be (4.5)² = 20.25 added <u>and </u>subtracted.
y = x² + 9x + 7
y = x² + 9x + 20.25 + 7 - 20.25
y = (x² + 9x + 20.25) - 13.25
y = (x + 4.5)² - 13.25
y = (x + 4.5)² - 13.25
Vertex Form is y = a(x-h)² + k, where the parabola vertex is (h, k)
So if you wrote this as y = 1(x - [-4.5] )² + (-13.25), we would see that a = 1, and h = -4.5 and k = -13.25.
Vertex = (-4.5, -13.25)
I verified on a graphing calculator that this is indeed the vertex of the parabola.
Answer:
x^2+2x
Step-by-step explanation: You would take x and multiply it by x and get X^2 then you would take x anm multiply it by 2 to get 2x. It is distributing

Answer:
-25.5
Step-by-step explanation:
Hi Baby girl,
59.2 - 84.7 can be worked out this way:
First calculate 84.7 - 59.2 on your rough paper
That gives 25.5
Finally make your answer a negative number (since the question is about subtracting a larger number from a smaller number)
The answer therefore is -25.5
