Answer: y = (x +2)² + 5
<u>Step-by-step explanation:</u>
y = a(x - h)² + k <em>where "a" is the leading coefficient and (h, k) is the vertex</em>
Since we don't know "a", we need to plug in the point (x, y) and the vertex (h, k) to solve for "a": (x, y) = (0, 9) and (h, k) = (-2, 5)
y = a(x - h)² + k
9 = a(0 - (-2))² + 5
9 = a(0 + 2)² + 5
9 = a(2)² + 5
<u>-5 </u> <u> -5 </u>
4 = a(4)
<u>÷4 </u> <u> ÷4 </u>
1 = a
Next, plug in "a" and the vertex (h, k):
y = a(x - h)² + k
y = 1(x +2)² + 5
y = (x +2)² + 5
Slope is 20/4
In this situation the slope means that Andre earns $20 every 4 weeks

Answer: Profit = 0.4x - 25
Step-by-step explanation:
Let x represent the number of cookies that he makes and sells.
Profit = Revenue - total cost
Manny purchased a set of cookie cutters for $25. The ingredients for his cookies will cost him $0.35 per Cookie. This means that his total cost of producing x cookies is
0.35x + 25
He plans to sell cookies for $0.75 each. This means that the revenue generated from selling x cookies is 0.75x
Therefore, the equation giving Manny's total profit per cookie as a function of the number of cookies he makes is
Profit = 0.75x - (0.35x + 25)
Profit = 0.75x - 0.35x - 25
Profit = 0.4x - 25
