To solve the inequality -12 ≥ (8/9)u, we need to isolate the variable u.
First, we can multiply both sides of the inequality by 9 to eliminate the fraction:
-12 * 9 ≥ (8/9)u * 9
-108 ≥ 8u
To isolate u, we can divide both sides of the inequality by 8:
-108/8 ≥ (8u)/8
-13.5 ≥ u
Therefore, the solution to the inequality is u ≤ -13.5.
Solve the inequality for u.
-12>=8/9u

To solve the inequality -12 ≥ (8/9)u, we can start by multiplying both sides of the inequality by 9 to eliminate the fraction:
-12 * 9 ≥ (8/9)u * 9
-108 ≥ 8u
Next, we can divide both sides of the inequality by 8:
-108/8 ≥ (8u)/8
-13.5 ≥ u
Since u must be less than or equal to -13.5, we can simplify the solution as:
u ≤ -14
-12 * 9 ≥ (8/9)u * 9
-108 ≥ 8u
Next, we can divide both sides of the inequality by 8:
-108/8 ≥ (8u)/8
-13.5 ≥ u
Since u must be less than or equal to -13.5, we can simplify the solution as:
u ≤ -14
