You have a gift card worth $90. you wanna buy several movies that are $12 each. write and solve an inequality that represents the number of movies you can buy with at least 30 dollars on the gift card

5 Movies and 12x≤90-30

Step-by-step explanation:

So first you would want to subtract the $30 from the $90 assuming you want to save $30 (I got 60 from 90-30) then you would divide 60 by 12 giving you 5

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! : )
