Answer:
Vertex is (-a, -6), where a ≠ 0.
General Formulas and Concepts:
<u>Algebra I</u>
- Coordinates (x, y)
- Quadratics
<u>Algebra II</u>
Vertex Form: y = a(bx - h)² + k
- <em>a</em> is the vertical scale factor
- <em>b</em> is the horizontal scale factor
- (h, k) is the vertex
Step-by-step explanation:
<u>Step 1: Define</u>
y = -3(x + a)² - 6
↓ <em>Identify variables</em>
<em>a</em> = -3
<em>b</em> = 1
(h, k) = (-a, -6)

Answer:
The expression T = 15*3 + 32 could be used to correctly calculate the amount Roberta owes Mr. Jones
Step-by-step explanation:
Given that:
Amount charged for parts = $32
Per hour labor = $15
Time spent on repairing = 3 hours
Total amount = Per hour labor * Number of hours + Amount of parts
T = 15*3 + 32
Hence,
The expression T = 15*3 + 32 could be used to correctly calculate the amount Roberta owes Mr. Jones
Answer:
A = C + 16
Step-by-step explanation:
Given
A = B + 12 and B = C + 4, then substitute B = C+ 4 into A, that is
A = C + 4 + 12
A = C + 16
