Use the information below to complete the problem: p(x) = (1)/(x + 1)

bija089 [108]

Given:

The functions are:

$p(x)=\dfrac{1}{x+1}$

$q(x)=\dfrac{1}{x-1}$

To find:

The rational expression for $p(x)-q(x)$ .

Solution:

We have,

$p(x)=\dfrac{1}{x+1}$

$q(x)=\dfrac{1}{x-1}$

Now,

$p(x)-q(x)=\dfrac{1}{x+1}-\dfrac{1}{x-1}$

$p(x)-q(x)=\dfrac{(x-1)-(x+1)}{(x+1)(x-1)}$

$p(x)-q(x)=\dfrac{x-1-x-1}{x^2-1^2}$ $[\because a^2-b^2=(a-b)(a+b)]$

$p(x)-q(x)=\dfrac{-2}{x^2-1}$

Therefore, the required rational expression for $p(x)-q(x)$ is $\dfrac{-2}{x^2-1}$ .

You buy one 10 packs of juice boxes.Each box contains the same number of ounces.how many ounces of juice did u buy

Travka [436]

Hello.

The amount of ounces of juice bought would be x(10). Because we don't know how much is in 1 box, it is x. x(10) = x*10. It is multiplied by 10 because you are buying 10 boxes of juice.
