A cell phone plan costs $200 to start. Then there is a $50 charge each month. what is the total cost (start up fee and monthly charge) to use the cell phone plan for one month?
I got $250

Part B
what is the total cost for x months?

Part D
Is there a proportional relationship between time and cost of the cell phone plan? Explain how you know.

Part E

what is the start-up fee and monthly cost for this plan?​

(23*2)-12=x     x=34

step-by-step explanation:

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

you 're wlecome! : )

the answer is 8/21

hope this
