Each square represents 8
If it is 10×10 then there is 100 squares
800÷100=8
This is a parabola that opens downward.
Remember that the axis of symmetry is located at x=-b/(2a).
So the vertex is at (3,-1)
So functions slope is positive or increasing on (-co, 3] and decreasing on [3,co).

Answer:
x is 30
Step-by-step explanation:
1/2 ( x + 6 ) = 18
1/2x + 3 = 18
- 3 - 3
1/2x = 15
· 2 · 2
x = 30
So there are a couple of different ways to write it but I find the easiest to be 28/9 or 3 1/9
