Solve the inequality $u + 8 \le 9$ and graph the solution on a number line.

1. Problem Description

Solve the inequality $u + 8 \le 9$ and graph the solution on a number line.

2. Solution Steps

To solve the inequality $u + 8 \le 9$, subtract 8 from both sides of the inequality:

$u + 8 - 8 \le 9 - 8$

$u \le 1$

The solution is $u \le 1$. This means $u$ can be any value less than or equal to

1. To graph the solution on the number line, we need to plot a closed circle (or filled-in circle) at 1 because $u$ can be equal to

1. Then we draw an arrow extending to the left, indicating that all values less than 1 are also solutions.

3. Final Answer

The solution to the inequality is $u \le 1$. The graph would show a closed circle at 1 and an arrow extending to the left.
