Answer:
2(3a + 6)
Step-by-step explanation:
2 × 3a = 6a
2 × 6 = 12
Do 0.94 x 10 which is 9.40
Therefore 10 oranges + 10 apples = $9.40
$10.05 - $9.40 = $0.65
Then, 1 apple is $0.65
B. zero
cuz the graphs are not intersecting anywhere. in order for their to be a solution. the graphs must intersect
Answer:
f(x) = -2x² + 12x - 11
General Formulas and Concepts:
- Order of Operations: BPEMDAS
- Expand by FOIL (First Outside Inside Last)
- Standard Form: f(x) = ax² + bx + c
- Vertex Form: f(x) = a(bx + c)² + d
Step-by-step explanation:
<u>Step 1: Define function</u>
Vertex Form: f(x) = -2(x - 3)² + 7
<u>Step 2: Find Standard Form</u>
- Expand by FOILing: f(x) = -2(x² - 6x + 9) + 7
- Distribute -2: f(x) = -2x² + 12x - 18 + 7
- Combine like terms (constants): f(x) = -2x² + 12x - 11
