Answer:
All real numbers except for 5.
Step-by-step explanation:

The domain of rational functions is determined by the denominator. The denominator cannot equal zero since if they do, the function will be undefined.
Thus, we need to find the zero(s) of the denominator to determine the domain.


Therefore, the domain of the rational function is all real numbers except for 5.

Answer:
<u>The equation is x = y * 4/5 and US$ 12 would equal 15 Swiss Francs</u>
Step-by-step explanation:
<u>1. Let's review all the information provided for solving this question:</u>
1 US$ equivalent to 1 1/4 Swiss Franc
2. Let's write and solve a multiplication equation to find the amount of US$ that would equal 15 Swiss Francs
x = Amount of US$ equivalent
y = Amount of Swiss Francs
x = y /1.25
x = y / 5/4 (1.25 = 5/4)
<u>x = y * 4/5</u>
Now, let's replace with the real values:
x = 15 * 4/5
x = 60/5
<u>x = 12</u>
<u>US$ 12 would equal 15 Swiss Francs</u>
