Which of the following relations is a function?

1 answer:

7 0

A function will NOT have any repeating x values, it can have repeating y values, just not the x ones. So which set has NO repeating x values ?
That would be { (1,3), (2,3), (4,3), (9,3)}....like I said, there can be repeating y values....just not the x ones. All of ur other answer choices have repeating x values.

The line a bus arrives at the bus stop every 25 minutes, and the line b bus arrives every 15 minutes.Both are at the stop right

vova2212 [387]

Answer:

after 75 minutes

Step-by-step explanation:

The least common multiple (LCM) of 15 and 25 is 75. It can be found a couple of ways:

1. List the factors of each number and find the product of the unique ones:

15 = 3·5

25 = 5²

The LCM is 3·5² = 75.

2. Find the greatest common divisor (GCD) and divide the product of the numbers by that value. From the above list of factors, we see that 5 is the GCD of 15 and 25. Then the LCM is ...

15·25/5 = 75

Or, you can simply list multiples of each number and see what the smallest number is that is in both lists:

15, 30, 45, 60, 75, 90

25, 50, 75, 100

The two buses will appear together again after 75 minutes.
