Answer:
Vertex(1,7)
Vertex form: ![f(x)=-2\left(x-1\right)^2+7](https://tex.z-dn.net/?f=f%28x%29%3D-2%5Cleft%28x-1%5Cright%29%5E2%2B7)
Step-by-step explanation:
Vertex form equations for x is ![v=-\frac{b}{2a}](https://tex.z-dn.net/?f=v%3D-%5Cfrac%7Bb%7D%7B2a%7D)
which the vertex here is
![-\frac{4}{2\left(-2\right)}](https://tex.z-dn.net/?f=-%5Cfrac%7B4%7D%7B2%5Cleft%28-2%5Cright%29%7D)
->
x = 1, plugin to find y, y = 7
Answer: C
Step-by-step explanation:because he will need to write an inequity to represent the total number of hours he can work each week . SO HE can see if he is making more then 120$ per week . No problem thanks me later

Step-by-step explanation:
Answer:
There are six equal surfaces of a cube. Then,
384 / 6 = 64 sq in (the area of one surface)
The area of one surface of a cube will be equal to x*x (if we let the edge length be x)
x^2 = 64
x = 8 inch
