To determine which of the given inequalities is not correct when y ≤ -2, we need to evaluate each inequality.

 

Option A, y + 3 ≤ 1

Given y ≤ -2

y + 3 ≤ -2 + 3 (add 3 to both sides)

y + 3 ≤ 1

This inequality is correct.

 

Option B, 2y ≤ -4

Given y ≤ -2

y × 2 ≤ -2 × 2 (multiply both sides by 2)

2y ≤ -4

This inequality is correct.
