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.

Damm [24]

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 = \frac{540}{30}

                                                      = 18.

So, he can take out $30 each week to go out to eat for 18 weeks only.
