I need help solving this for pre calc

Katarina [22]

Starting with:

$\frac{2p}{p+1} + \frac{3}{p-1} = \frac{15-p}{p^{2}-1}$

First, the difference of 2 squares shows that $p^{2} - 1 = (p+1)(p-1)$

Sub that in and multiply both sides by $(p-1)(p+1)$ :

$\frac{2p(p+1)(p-1)}{p+1} + \frac{3(p-1)(p+1)}{p-1} = \frac{(15-p)(p-1)(p+1)}{(p-1)(p+1)}$

This easily simplifies to $2p(p-1) + 3(p+1) = 15 - p$

See if you can continue from here. If not, leave a comment and I or someone else can show you the rest.

Which of the following are the correct properties of slope? Check all that apply

victus00 [196]

A. The slope of a flat line is smaller than the slope of a steep line with a positive slope.

D. A negative slope means that the line moves down from left to right.

E. The slope of a flat line should be exactly 0.

The general slope intercept form equation is;

y = mx + c

where;

m is the slope(rate of change)
