Answer:
A rational expression is a ratio of two polynomials. The domain of a rational expression is all real numbers except those that make the denominator equal to zero.
Step-by-step explanation:
Answer:

Step-by-step explanation:
Split it up like this to make it easier to work with:

Since the only thing in the denominator of those fractions is a 3, we can only divide the 27 by 3, not the x or y terms. Same thing with the second fraction. 27 divided by 3 is 9 and 15 divided by 3 is 5, so

is the solution. It is not completely simplified, but that isn't what you asked for, so this should suffice as the answer.
Answer:
AC with endpoints at A(1; -1) and C(5; 3)
x-intercept when y = 0
Look at the graph, when y = 0, x = 2
So x-intercept (2, 0)
Answer
C. (2,0)
The graph that best relates is F because it starts from lowest to highest which is what the graph is showing
