Answer:

$- \frac{1}{6}$

Step-by-step explanation:

$- \frac{8}{3} + \frac{5}{2} \\ - \frac{8 \times 2}{3 \times 2} + \frac{5 \times 3}{2 \times 3 } \\ - \frac{16}{6} + \frac{15}{6} \\ = - \frac{1}{6}$

Answer:

Step-by-step explanation:

Inequalities of the type | x | > a, always have solutions of the form

x < - a or x > a

This can be extended to expressions, that is

14 - 5x < - 8 OR 14 - 5x > 8 ( subtract 14 from both sides of both inequalities )

- 5x < - 22 OR - 5x > - 6

Divide both sides by - 5 , reversing the inequality sign as a consequence

x > $\frac{22}{5}$ OR x < $\frac{6}{5}$

That is the solution is

x < $\frac{6}{5}$ OR x > $\frac{22}{5}$

F(x) = x°-9x

laila [671]

F(x)=x^3-9x
and
g(x)=x^2-2x-3

so you just need to divide f(x) by g(x)

Therefore:

f(x)/g(x) = (x^3-9x) / (x^2-2x-3)

and of course you need to factor these two function to see if some factor would cancel another

x^3-9x = x(x^2-9)=x(x-3)(x+3)
and
x^2-2x-3 = (x-3)(x+1)
