-5x -10 >30 help Hehehehehe.

Mnenie [13.5K]

Answer:

x<-8

Step-by-step explanation:

-5x-10>30

(add 10 to both sides)

-5x-10+10>30+10

-5x>40

$\frac{-5x}{-1}$ < $\frac{40}{-1}$

(dividing through by -1 changes the sign of the inequality from "<" to ">")

5x<-40

(dividing through by 5)

$\frac{5x}{5}$ < $\frac{-40}{5\\}$

x<-8

F(x)=2x^2+4x-16<br> g(x)=4x^2-16<br> Find (f/g)(x).

Nastasia [14]

Answer:

Step-by-step explanation:

$(\frac{f}{g} )(x) = \frac{2x^{2} +4x-16}{4x^{2} -16}$

2x²+4x -16 = 2(x²+2x-8); factor 2

= 2(x+4)(x-2) ;factor the quadratic equation

4x²-16 = 4(x²-4) ; factor 4

=4(x²- 2²) ; rewrite 4 as 2²

= 4(x-2)(x+2); now use the difference of two squares a²-b²=(a-b)(a+b)

so now we have:

$(\frac{f}{g}) (x) = \frac{2(x+4)(x-2)}{4(x-2)(x+2)}$ ; simplify (x-2) from numerator and denominator

and 2/4 as 1/2

$(\frac{f}{g}) (x) = \frac{(x+4)}{2(x+2)}$
