Answer:
- C. f(x) = x³ + 10x² + 7x - 18
Step-by-step explanation:
If the function has a factor of x + 9, then the function will have a zero output at x = -9
<u>Lets verify:</u>
- A. f(-9) = (-9)³ - 8*(-9)² - 11*(-9) + 18 = -1260, No
- B. f(-9) = (-9)³ + 10*(-9)² + 7*(-9) - 27 = -9, No
- C. f(-9) = (-9)³ + 10*(-9)² + 7*(-9) - 18 = 0, Yes
- D. f(-9) = (-9)³ - 8*(-9)² + 11*(-9) + 27 = -1449, No

Step-by-step explanation:
If n is number of nickles and d is number of dimes:
5n + 10d = 440
n = 3.5d
Substitute:
5(3.5)d + 10d = 440
17.5d + 10d = 440
27.5d = 440
d = 16
