The equation for this is ; y=1/2(x+4)^2-1
Explain
we use the vertex form
y=a(x-h)^2+k where the vertex is (h,k)
Select ( -4,-1)
Where h=-4
K=-1
y=a(x-h)^2+k
We get
y=a(x-(-4))^2+ -1
Y= a(x+4)^2+-1
Now replace to 0,7
7=a(0+4)^2-1
7=a(4)^2-1
7=16a-1
So now
7=16a-1
7+1=16a
8=16a
a=8/16
That should 1/2
So y=a(x+4)^2 -1
Should become
Y=1/2(x+4)^2 -1

Answer:
Martina 29, Scott 23 and Jim 69.
Step-by-step explanation:
We are told that:
Martina served six more X orders than Scott (X+6).
So, Scott served X orders.
And Jim served 3 times X order as Scott.
We will have then:
X + (X+6) + 3X = 121
5X + 6 = 121
5X = 121 - 6
5X = 115
X = 115/5
X = 23
So, Scott served 23 orders, Martina 29 and Jim 69.
15. She bought:
3 jeans, $20 each
1 pants, $18
You find the total: 3(20) + 1(18) = $78 then you apply the discount
Since this is between 50-100, you use the 38% discount (decimal form: 0.38)
38% is being subtracted from your total, so you can do this:
100% - 38% = 62% This is your total after the discount
78(0.62) = 48.36 Your answer is C
