Question

solve the inequality for u.

u - 9 ≤ -15

simplify your answer as much as possible.

Explanation:

Step1: Add 9 to both sides

To isolate \( u \), we add 9 to both sides of the inequality \( u - 9 \leq -15 \). This gives \( u - 9 + 9 \leq -15 + 9 \).

Step2: Simplify both sides

Simplifying the left side, \( u - 9 + 9 = u \). Simplifying the right side, \( -15 + 9 = -6 \). So we get \( u \leq -6 \).

Answer:

\( u \leq -6 \)
