Answer:
A. 16
Step-by-step explanation:
![x^{3} + x^{2} - x(4)\\= x^{3} +x^{2} + (4x^{2})\\= 3x{3} + 2x^{2} + 4x\\= 9x + 5x + 4x\\= 12x + 4x\\\\x = 16](https://tex.z-dn.net/?f=x%5E%7B3%7D%20%2B%20x%5E%7B2%7D%20-%20x%284%29%5C%5C%3D%20x%5E%7B3%7D%20%2Bx%5E%7B2%7D%20%2B%20%284x%5E%7B2%7D%29%5C%5C%3D%203x%7B3%7D%20%2B%202x%5E%7B2%7D%20%2B%204x%5C%5C%3D%209x%20%2B%205x%20%2B%204x%5C%5C%3D%2012x%20%2B%204x%5C%5C%5C%5Cx%20%3D%2016)

Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify.</em>
9x - 5y = -9
(a - 1, 9)
<u>Step 2: Solve for </u><em><u>a</u></em>
- Substitute in coordinate [Equation]: 9(a - 1) - 5(9) = -9
- Evaluate [Order of Operations]: 9(a - 1) - 45 = -9
- [Addition Property of Equality] Add 45 on both sides: 9(a - 1) = 36
- [Division Property of Equality] Divide 9 on both sides: a - 1 = 4
- [Addition Property of Equality] Add 1 on both sides: a = 5
