2.5x-4=41 solve for the x

Simplifying

2.5x + -4 = 41

Reorder the terms:

-4 + 2.5x = 41

Solving

-4 + 2.5x = 41

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '4' to each side of the equation.

-4 + 4 + 2.5x = 41 + 4

Combine like terms: -4 + 4 = 0

0 + 2.5x = 41 + 4

2.5x = 41 + 4

Combine like terms: 41 + 4 = 45

2.5x = 45

Divide each side by '2.5'.

x = 18

50-38=12

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! : )
