Answer:

The correct answer would be C.

Step-by-step explanation:

{(1, 2); (2, 2); (3, 2); (4, 2)}

A function doesn't let its x-coordinates repeat.  In the first option, 2 repeats.  In the second option, 1 repeats.  In the 4th option, 1 repeats.

Hope this helps! :)

You bought a bag of tamales and one of your friends ate 1/5 of the entire bag and another friend ate 1/3 of the whole bag. How m
Serggg [28]

Answer:

There is 7/15 left in the bag

Step-by-step explanation:

So, you need to find a common denominator between 3 and 5 which is 15

multiply the numerator and the denominator by 3 in 1/5. Then, multiply the numerator and the denominator by 5 in 1/3.

1/3*5=5/15

1/5*3=3/15

Add them together.

5/15+3/15=8/15

Lastly, subtract 15/15 by 8/15

15/15-8/15=7/15
