The function can be expressed as a rational function is 
.
We have to determine
Which of the following is written as a rational function?
According to the question
A rational function is a function that can be expressed as the quotient or ratio of two polynomial functions, where the polynomial in the denominator must have a degree of at least 1.
A rational function can be expressed as;
Then,
The required rational function is expressed as;
Where p(x) is (x-5) and g(x) is 3x.
Therefore,
The function is,
Hence, the function can be expressed as a rational function is .

Answer:
I don't really know what is that?
Answer:
1.ABC is equilateral triangle because all sides are equal
3.because they are the joined figure of a triangle
Answer:
The answer is A. 5 notebooks and 13 pencils
Step-by-step explanation:
1. Identify your x and y variables.
x - number of notebooks
y - number of pencils
2. Set up two equations to come up with a system of linear equations.
x + y = 18
2.3x + 1.25y = 27.75
3. In order to solve for one of the variables (either x or y), multiply the first equation with the additive inverse (when added together, the answer is zero; one number will be positive while the other number will be negative) of the coefficient of either x or y, so you can eliminate that variable. In this case, I choose the coefficient of y which is 1.25. So, the first equation will look like this:
-1.25(x + y) = 18
-1.25x - 1.25y = -22.50
4. Next, eliminate the y variable and solve for x.
-1.25x - 1.25y = -22.50
2.3 x + 1.25 y = 27.75

x = 5 Joanna bought 5 notebooks.
5. Then, solve for y.
5 + y = 18
y = 18 - 5
y = 13 Joanna bought 13 pencils.
If you want to check your work, just plug in 5 and 13 into one of the two original equations. Simplify the equations, and you should get a true statement.
5 + 13 = 18
18 = 18
