Identify the equations that have one solution, infinitely many solutions, or no solution. a. 1/2y + 3.2y = 20 b. 15/2 + 2z = 1/4 = 4z + 29/4 - 2z c. 3z + 2.5 = 3.2 + 3z d. 1.1 + 3/4x + 2 = 3.1 = 3/4x e. 4.5r = 3.2 + 4.5r f. 2x + 4 = 3x + 1/2

need more information

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! : )
