L: Large
s: Small
-2 (2L + 3s = 46)
4L + 8s = 105
-4L - 6s = -92
4L + 8s = 105
2s = 13
s = 6.5 kilograms
2L + 3 ( 6.5 ) = 46
2L + 19.5 = 46
2L = 26.5
L = 13.25 kilograms.

Answer:
{(-1,4), (2,7), (3,7)} is a function
Step-by-step explanation:
For something to be a function, any given x must have one and only one y
{(-1,-3), (3,2), (3,7)}
-1(x) only has -3(y)
3(x) has 2(y) and 7(y), making it not a function
{(-3,7), (3,-7), (3,7)}
-3(x) only has 7(y)
3(x) has -7(y) and -7(y, making it not a function
{(-1,4), (-1,7), (3,5)}
3(x) only has 5(y)
-1(x) has 4(y) and 7(y), making it not a function
{(-1,4), (2,7), (3,7)}
-1(x) only has 4(y)
2(x) only has 7(y)
3(x) only has 7(y)
This is a function
