Xander needs to collect at least 120 cans for a food drive to earn community service credit. He has already collected 64 items. Part A
Choose the inequality and solution to represent the number of cans, x, that Xander must still collect.
(A) x + 64 ≤ 120; x ≤ 56
(B) x + 120 ≤ 64; x ≤ –56
(C) x + 64 ≥ 120; x ≥ 56
(D) x + 120 ≥ 64; x ≥ –56
Part B
Choose the graph of the solution on the number line.
(A) A number line with a closed dot at 56 shaded to the left.
(B) A number line with a closed dot at 56 shaded to the right.
(C) A number line with a closed dot at negative 56 shaded to the left.
(D) A number line with a closed dot at negative 56 shaded to the right.

(x+3)(x+7)

step-by-step explanation:

there is no grid

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! : )
