Final answer:
The solution to r(x)=(x-3)/(x-5) is x = 3.
Step-by-step explanation:
The function r(x)=(x-3)/(x-5) represents a rational function. To find all the solutions to r(x), also known as the x-intercepts or roots of the function, we set r(x) equal to zero and solve for x. In this case, we have:
(x-3)/(x-5) = 0
By multiplying both sides of the equation by (x-5), we get:
x - 3 = 0
Adding 3 to both sides, we obtain:
x = 3
Therefore, the only solution to r(x) is x = 3.
