Answer:
The answer to the first question is (5,1).
Answer:
B.
no real solutions
Step-by-step explanation:
2(x + 11) + 5x = 7x - 22
Distribute
2x+22 +5x = 7x -22
Combine like terms
7x +22 = 7x-22
Subtract 7x from each side
7x-7x+22 = 7x-7x-22
22 = -22
This is never true so there are no solutions

<u>Step 1: Define</u>
<em>Identify</em>
f(x) = 1 - x² + x³
f(-1) is <em>x</em> = -1 for the function f(x)
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em> [Function f(x)]: f(-1) = 1 - (-1)² + (-1)³
- Exponents: f(-1) = 1 - 1 - 1
- Subtract: f(-1) = -1
