Which values of x and y are solutions to the open sentence?       4y ≥ 3x + 2   A. x = 3, y = 0   B. x = 4, y = 3   C. x = 6, y
kobusy [5.1K]
Your answer would be C. x = 6, y = 5
This is because if you plug the numbers in to the inequality, we get:
(4 × 5) ≥ (3 × 6) + 2
20 ≥ 18 + 2
20 ≥ 20
which is correct.

I hope this helps!
