Solve for x:

20- 3x= -3(x-8)

Let's solve your equation step-by-step.

20−3x=−3(x−8)

Step 1: Simplify both sides of the equation.

20−3x=−3(x−8)

20+−3x=(−3)(x)+(−3)(−8)(Distribute)

20+−3x=−3x+24

−3x+20=−3x+24

Step 2: Add 3x to both sides.

−3x+20+3x=−3x+24+3x

20=24

Step 3: Subtract 20 from both sides.

20−20=24−20

0=4

There are no solutions.

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! : )
