Answer:
Given information :
![f(x) = 2x^2-2x+7\\g(x) = x^2+9x-6](https://tex.z-dn.net/?f=f%28x%29%20%3D%202x%5E2-2x%2B7%5C%5Cg%28x%29%20%3D%20x%5E2%2B9x-6)
Find f(x) - g(x)
![f(x)-g(x) = (2x^2-2x+7) - (x^2+9x-6)](https://tex.z-dn.net/?f=f%28x%29-g%28x%29%20%3D%20%282x%5E2-2x%2B7%29%20-%20%28x%5E2%2B9x-6%29)
Distribute the negative to the second polynomial
![f(x)-g(x)=2x^2-2x+7 -x^2 -9x + 6](https://tex.z-dn.net/?f=f%28x%29-g%28x%29%3D2x%5E2-2x%2B7%20-x%5E2%20-9x%20%2B%206)
optional : rearrange the terms
![f(x)-g(x)=2x^2-x^2-2x-9x+7+6](https://tex.z-dn.net/?f=f%28x%29-g%28x%29%3D2x%5E2-x%5E2-2x-9x%2B7%2B6)
Combine like terms and find f(x) - g(x)
Answer:
The correct answer is A or C 0.05n < 0.45
Step-by-step explanation:
Nickels cost $0.05 and n is the number of nickels, so you multiply the two to get 0.05n. Since this value is less than $0.45, we put a less than sign.
