Answer:
All of them.
Step-by-step explanation:
For rational functions, the domain is all real numbers <em>except</em> for the zeros of the denominator.
Therefore, to find the x-values that are not in the domain, we need to solve for the zeros of the denominator. Therefore, set the denominator to zero:

Zero Product Property:

Solve for the x in each of the three equations. The first one is already solved. Thus:

Thus, the values that <em>cannot</em> be in the domain of the rational function is:

Click all the options.
The rate of change is meaning the slope. The slope of A is 8, therefore, the answer would be 7.
hope this helps :)
Do a proportion.
5/32= x/800
Cross multiply and divide
800 x 5= 4,000
4,000 divided by 32= 125
So answer is 125 students
8 children ($4 x 8 = $32)
2 adults ($6 x 2 = $12)
2 senior citizens ($3 x 2 = $6)
32+12+6 = 50
The unit rate is 5cm per 1min
