Step-by-step explanation:
<u>Step 1: Define</u>
-8x² + 3 - 9x² + 3x - 3
<u>Step 2: Simplify</u>
- Combine like terms (x²): -17x² + 3x + 3 - 3
- Combine like terms (Z): -17x² + 3x
Answer:
85000
Step-by-step explanation:
7908000 - 7848000 = 60000
The first 10000 litres is #1 per litre or 10000
The remaining 5 litres is 50000 * 1.5 = 75000

<u>Algebra I</u>
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
f(x) = 3x² - x + 5
g(x) = 2x - 3
<u>Step 2: Find f(x) - g(x)</u>
- Substitute in function values: f(x) - g(x) = 3x² - x + 5 - (2x - 3)
- [Distributive Property] Distribute negative: f(x) - g(x) = 3x² - x + 5 - 2x + 3
- [Subtraction] Combine like terms (x): f(x) - g(x) = 3x² - 3x + 5 + 3
- [Addition] Combine like terms: f(x) - g(x) = 3x² - 3x + 8
