Answer:
It subtracts
Step-by-step explanation:
A pair of numbers is a solution of y = -3x if the second number, y, is -3 times the first number, x.
What about the pair (-1, 4)? If you replace x with -1, you get y = -3(-1) = 3, not 4. So (-1, 4) is NOT a solution.
For each answer choice, you have to check all three of the given pairs.
(0, 0) is a solution because if x = 0, then y = -3(0) = 0.
(3, -9) is a solution because if x = 3, then y = 3(-3) = -9.
Can you finish it?
The store clerk will need to pack 8 boxes. This is because you have to divide 45 by 6 and you 7.5, but you can not split the box in half, so you need to round up since you have to pack all the shirts and you get 8.
