The 70 represents the number of people waiting to by tickets at the exactly moment when the ticket booth is opened.
Step-by-step explanation:
The 70 represents the number of people waiting to by tickets at the exactly moment when the ticket booth is opened.
You can see this by setting the x value to 0, it is, in the precise moment when the booth opened (as x cant be negative, because there is no negative time, you could also think of 70 as the number of people waiting before the booth opens).
For question 4 the answer is yes and for question 5 the answer is false
<h2>
Answer: A. Both are rational.</h2>
Step-by-step explanation:
Although both expressions have square roots, the result of each square root is an integer, which can be expressed as a fraction.
In this sense:
Rational numbers are all numbers that can be represented as the quotient (division) of two integer numbers. This means they can be represented as a fraction in which the denominator is nonzero.
If we solve both expressions, we will be able to see that the result is an integer that can be expressed as a fraction with two integers:
The result is an integer

The result is an integer
