Answer:
9
Step-by-step explanation:
17.91 divided by 1.99
Anything raised to the 0 power = 1
The point-slope form:

- slope
- point
We have the point
and the slope 
Substitute:

We have
3 / (x-5) - x/5
We make the GCF and we have
15/[ 5(x-5) ] - x(x-5)/[ 5(x-5)]
= [ 15 - x(x-5) ] [5(x-5)]
= [ 15 - x^2 + 5x] / [ 5 (x-5) ]
= [15 - x^2 + 5x]/[5x - 25]
An answer to your question is (15-x^2+5x)/(5x-25)
