-2x + 1 = -4x +9 what is x?

x = 4

Step-by-step explanation:

Original Problem: 2x + 1 = -4x +9

1. Subtract 1 from both sides

-2x+1-1=-4x+9-1

2. Simplify

-2x=-4x+8

3. Add 4x to both sides

-2x+4x=-4x+8+4x

4. Simplify

2x=8

5. Divide both sides by 2

2x/2 = 8/2

x = 4

for this case we have the following expression:

to solve, we rewrite the expression as:

we apply double c and we have:

thus, the quotient is 48.

so, patel found a wrong ratio and the multiplication was incorrect.

option d

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! : )
