13/12 or 1 1/12. The first one is an improper number, the second is proper. hope this helps :)
Answer:
First option
![y = (x-7) ^ 2 + 9](https://tex.z-dn.net/?f=y%20%3D%20%28x-7%29%20%5E%202%20%2B%209)
Step-by-step explanation:
In this case we must write a quadratic equation in the vertex form.
We have the vertice. (7, 9)
We know that the vertex form for a quadratic equation is:
.
Where (h, k) is the vertex.
So if the vertex is (7, 9), the equation sought is:
![y = (x-7) ^ 2 + 9](https://tex.z-dn.net/?f=y%20%3D%20%28x-7%29%20%5E%202%20%2B%209)
Therefore the answer is the first option.
Answer:
n=80
Step-by-step explanation:
n+75=155
Take away 75 by doing -75 to level it out.
Then you have n = 80.
Answer:
all of them....take -5, -5*5+8=-25+8,definitely negative....and if -5 is negative, other more extreme options are even more negative

Answer:
26 y + 5
Step-by-step explanation:
Simplify the following:
7 3 y + 4 3 y - 3 y - 2 2 y + 5
7×3 = 21:
21 y + 4 3 y - 3 y - 2 2 y + 5
-2×2 = -4:
21 y + 4 3 y - 3 y + -4 y + 5
4×3 = 12:
21 y + 12 y - 3 y - 4 y + 5
Grouping like terms, 21 y + 12 y - 3 y - 4 y + 5 = (21 y - 4 y + 12 y - 3 y) + 5:
(21 y - 4 y + 12 y - 3 y) + 5
21 y - 4 y + 12 y - 3 y = 26 y:
Answer: 26 y + 5
