Answer:

  (a variation of) vertex form

Step-by-step explanation:

For vertical scale factor "a" and vertex (h, k), the vertex form of the equation for a parabola can be written as ...

  y = a(x -h)^2 +k

If k is subtracted from this equation, an alternate form is ...

  y -k = a(x -h)^2

This latter version of vertex form is the form your equation has, where ...

  • a = 8
  • (h, k) = (-7, -20)

crimeas [40]

Answer:

2 weeks

Step-by-step explanation:

Given in the question that,

Equation that represent Lisa's total amount of money

f(x) = 20 - 13x

Equation that represent Joey's total amount of money

g(x) = x² - 10

To find weeks, x, after which they will have same amount of money, we will equate both equation

<h3>20 - 13x =  x² - 10</h3>

x² - 10 - 20 + 13x = 0

x² - 30 + 13x = 0

x² + 13x - 30 = 0

(x - 2)(x + 15) = 0

x = 2 or x = -15

Weeks, x, can not be negative so we will reject x = -15

Hence, after 2nd week Lisa and Joey will have the same amount of money save.

Oksana_A [137]

Answer:

96

Step-by-step explanation:

Total goals scored by peter in second season = 15

In first season he was said to have scored 6 fewer goals. 15-6 = 9

The team as a whole scored 4times as much as peter did.

Let's call the total number of goals peter scored , T

So t = 15 + 9 = 24

4 times as much as peter = 4 x T

= 4x24

= 96 goals in both seasons were scored by the team.
