Answer:
We have been given the equation:

And x=10
Substitute the given x in the given equation we get:


On simplification we get:

Required solution is: x= 10 and y=-20
The solution to the system of equation is those points that satisfy the given system of equations.
Answer:
2 vertical asymptotes occurring at x = 5 and x = -1
Step-by-step explanation:
given

recall that asymptotic occur at the locations that will make the equation undefined. In this case, the asymptote will occur at x-locations which will cause the denominator to become zero (and hence undefined)
Equating the denominator to zero,
(x-5)(x+1) = 0
(x-5) =0
x = 5 (first asymptote)
or (x+1) = 0
x = -1 (2nd asymptote)
