Can somebody help me with my packet please :D

Number 1 = 5        Number 2 = 13/12 or 1 and 1/12

Step-by-step explanation:

The properties of triangles states that the third side is no less than the difference between the other 2 sides. So we can subtract B from A in number 1 to get 5. In number 2, we need to convert them both into twelfths in order to find the difference, 2/3 is 8/12 and 1 3/4 = 7/4.  7/4 in twelfths is 21/12. Now we subtract and ignore the denominators, 21 - 8 is 13. You now have 13/12 for number 2.

Hope this helps.

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!
