Answer:
0
Step-by-step explanation:
This equation is in "vertex form," meaning that you can identify the vertex and other features of the graph from the equation.
y = a(x -h)² +k . . . . . the vertex is (h, k); the vertical scale factor is "a"
Comparing to your equation, you see ...
a = -1/2, h = 3, k = -1
The vertex is (h, k) = (3, -1). The vertical scale factor is negative.
__
This tells you the graph opens downward (the scale factor is negative), and the vertex (maximum point) is below the x-axis. (It has a negative y-coordinate.)
Because it start below the x-axis and goes down from there, the graph does not intersect the x-axis. There are zero (0) x-intercepts.

x=9
Answer:
18 weeks
Step-by-step explanation:
Initial amount stored in savings account = $700
Final minimum amount required in the account = $150.
Thus,
The total amount of money he can spend = (700 - 150) = $550
Each week he is withdrawing $30 to go out to eat.
Since , maximum money he can spend should be multiple of 30 ,
Thus maximum he can spend $540
number of weeks he can do this = 
= 18.
So, he can take out $30 each week to go out to eat for 18 weeks only.
Answer: All of these expressions have the same value because the answer will always be 20.
