Answer: The percent of US adults spend above 29 hours per month on PC internet = 50%
Step-by-step explanation:
Given: , US adults spent on average 29 hours per month using the PC internet.

Then, the percent of US adults spend above 29 hours per month on PC internet = 50%
Step-by-step explanation:
multiplying the 2nd eqn by 9 we get,
9x+9y=81
then,subtracting 1st and 2nd eqn
9x+5y=41
9x+9y=81
- - -
__________
0. -4y=-40
we get y = 10
then we get x=9-y
x=9-10
x= -1
so x is -1 and y is 10
Answer:
f(x)-g(x)=5x^3-17x^2+4 which appears as option A
Step-by-step explanation:
Simply subtract the function's expressions as shown below, and combine like terms to express the final result:
![f(x)=7x^3-10x^2-5\\g(x)=2x^3+7x^2-9\\f(x)-g(x)=7x^3-10x^2-5-[2x^3+7x^2-9]\\f(x)-g(x)=7x^3-10x^2-5-2x^3-7x^2+9\\f(x)-g(x)=7x^3-2x^3-10x^2-7x^2-5+9\\f(x)-g(x)=5x^3-17x^2+4](https://tex.z-dn.net/?f=f%28x%29%3D7x%5E3-10x%5E2-5%5C%5Cg%28x%29%3D2x%5E3%2B7x%5E2-9%5C%5Cf%28x%29-g%28x%29%3D7x%5E3-10x%5E2-5-%5B2x%5E3%2B7x%5E2-9%5D%5C%5Cf%28x%29-g%28x%29%3D7x%5E3-10x%5E2-5-2x%5E3-7x%5E2%2B9%5C%5Cf%28x%29-g%28x%29%3D7x%5E3-2x%5E3-10x%5E2-7x%5E2-5%2B9%5C%5Cf%28x%29-g%28x%29%3D5x%5E3-17x%5E2%2B4)
I dont know the answer to that question.
