Answer:
The vertex is at (1, -108).
Step-by-step explanation:
We have the function:

And we want to find its vertex point.
Note that this is in factored form. Hence, our roots/zeros are <em>x</em> = 7 and <em>x</em> = -5.
Since a parabola is symmetric along its vertex, the <em>x-</em>coordinate of the vertex is halfway between the two zeros. Hence:

To find the <em>y-</em>coordinate, substitute this back into the function. Hence:

Therefore, our vertex is at (1, -108).
Answer: 15
Step-by-step explanation: Take 12 and change the -3 to a regular 3.
(12 + 3 = 15.)
Whichever number in the question that’s bigger determines what integer it will have.

Which of the following can be used to prove that triangle EFG is also a right triangle?
D. Prove that KL is equal to c by the Pythagorean Theorem
Since we know that both triangles have a and b in common, the same side lengths, then KL must be equal to c as well. Using the Pythagorean Theorem, this can be proved. And because the Pythagorean Theorem can only be used on a right triangle, then triangle EFG must also be a right triangle if KL if also equal to c.
Hope this helps!! :)
Answer:
13.5
Step-by-step explanation:
2/3=9/x
2x=9*3
2x=27
x=27÷2
x=13.5
