How do you solve and simplify

DedPeter [7]

F(x) = 1/(x+2) & g(x) = x/(x-3)

(f(x) + g(x) = 1/(x+2) + x/(x-3). Reduce to same denominator:

1/(x+2) + x/(x-3) =(x-3) + x(x-3)/(x+2).(x-3) ==> (x²+3x-3)/(x+2).(x-3)

What is the slope of the line

cupoosta [38]

Answer:

I believe the slope would be -2

Step-by-step explanation:

The line goes down 2 boxes and over 1 box before it intersects with another point. Knowing slope = $\frac{rise}{run}$ , we know that slope = $\frac{-2}{1}$ which is equal to -2.
