Answer:

The x-intercepts of the quadratic function are -7 and 5.

Step-by-step explanation:

The given function is

f(x)=x^2+2x-35

Equate f(x)=0, to find the x-intercepts of the function.

x^2+2x-35=0

x^2+7x-5x-35=0

x(x+7)-5(x+7)=0

(x+7)(x-5)=0

x+7=0\Rightarrow x=-7

x-5=0\Rightarrow x=5

Therefore the x-intercepts of the quadratic function are -7 and 5.

An Internet service provider charges $9.95/month for the first 20 hours and $0.50 for each additional hour. Write an expression
inn [45]
I= 9.95 + .5h

20-35=15
I = 9.95+.5(15)
9.95+7.5
I = 17.45

If you used the internet for 35 hours, your bill would be $17.45
