Answer:
:The correct answer is :y = 8(x + 2)^2 + -15Step-by-step explanation:I just got the question correct.
1. P = IRT....for T
P / (IR) = T
2. A = 2(L + W)....for W
A/2 = L + W
(A/2) - L = W
3. y = 5x - 6...for x
y + 6 = 5x
1/5y + 6/5 = x....or (y + 6)/5 = x
4. 2x - 3y = 8....for y
-3y = -2x + 8
y = 2/3x - 8/3
5. not exactly sure of the equation here.....(x + y) / 3 = 5 ?? or 3(x + y) = 5 ??
6. y = mx + b....for b
y - mx = b
7. ax + by = c....for y
by = c - ax
y = (c - ax)/b...or y = (c/b) - (ax/b)
To get 10 % you have to divide by 10 .
so 154.99 ÷ 10 = 15.499.
that's 10% but you want 20% so you times 10% by 2.
15.499 X 2 = 30.998.
154.99 - 30.998 = 123.992.
you then need to round the answer so you get $123.99
Hope this helps!!
