Jacob is ordering custom t-shirts for his soccer team. long-sleeved shirts cost $15 each and short-sleeved shirts cost $10 each. jacob can spend at most $250 and he wants to order at least 20 shirts. let x represent the number of long-sleeved shirts. let y represent the number of short-sleeved shirts. select all inequalities that represent constraints for this situation. 15x 10y≥20 15x 10y≥250 x y≤250 x y≤20 15x 10y≤250 x y≥20

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!
