The solutions for the inequality -1 $\geq$ y+12 are numbers 11 and below.

Work Step by Step

First, you isolate y by subtracting 12 on both the sides resulting with, -14 ≥ y. The solutions that are possible are 11 and below because 11-12=-1 and that is one of the inequalities condition. As you decrease the number it still follows the pattern. Therefore, any number below 11 and 11 itself make this inequality valid.
