Adrian purchases 6 tubes of paint and 3 paintbrushes at a craft store. each tube of paint costs $2.50 and each paintbrush costs $0.50. he has a coupon for $2.00 off his purchase. how much does he pay?

$14.50

Step-by-step explanation:

6 x $2.50 = $15.00

3 x $0.50 = $1.50

$15.00 + $1.50 = $16.50

$16.50 - $2.00 = $14.50

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! : )
