ANSWER

( \frac{f}{g} )(x) =   \frac{1}{3} ( {x}^{2} + 3x + 9)

EXPLANATION

The given functions are

f(x) =  {x}^{3}  - 27

and

g(x) = 3x - 9

( \frac{f}{g} )(x) =  \frac{f(x)}{g(x)}

( \frac{f}{g} )(x) =  \frac{ {x}^{3}  - 27}{3x - 9}

( \frac{f}{g} )(x) =  \frac{ (x - 3)( {x}^{2} + 3x + 9) }{3(x -3 )}

Cancel the common factors,

( \frac{f}{g} )(x) =  \frac{  {x}^{2} + 3x + 9 }{3}

OR

( \frac{f}{g} )(x) =   \frac{1}{3} ( {x}^{2} + 3x + 9)

Solve 3x-2/4 - 2x+5/3 = 1-x/6
Nadya [2.5K]

Answer:

Pasos para resolver una ecuación lineal

3x−2/4−2x+5/3=1−x/6

Multiplique ambos lados de la ecuación por 12, el mínimo común denominador de 4,3,6.

36x−3×2−24x+20=12−2x

Multiplica −3 y 2 para obtener −6.

36x−6−24x+20=12−2x

Combina 36x y −24x para obtener 12x.

12x−6+20=12−2x

Suma −6 y 20 para obtener 14.

12x+14=12−2x

Agrega 2x a ambos lados.

12x+14+2x=12

Combina 12x y 2x para obtener 14x.

14x+14=12

Resta 14 en los dos lados.

14x=12−14

Resta 14 de 12 para obtener −2.

14x=−2

Divide los dos lados por 14.

x=
