Step-by-step explanation:
<u>Step 1: Define</u>
w(n) = n² + 6
w(-9) is n = -9
<u>Step 2: Evaluate</u>
- Substitute: w(-9) = (-9)² + 5
- Exponents: w(-9) = 81 + 5
- Add: w(-9) = 86
To simplify that equation you would first subtract 8 from both sides, getting 7x=28. You would then divide both sides by 7, getting x=4.
