1. Problem Description

The problem is to solve the inequality u+1620u + 16 \ge 20 and graph the solution on a number line.

2. Solution Steps

First, we need to isolate the variable uu. To do this, we subtract 16 from both sides of the inequality:
u+16162016u + 16 - 16 \ge 20 - 16
u4u \ge 4
The solution to the inequality is u4u \ge 4. This means that uu can be any number greater than or equal to
4.
To graph the solution, we need to draw a number line. Place a closed circle (or a filled-in circle) at 4 to indicate that 4 is included in the solution set. Then, draw an arrow to the right to indicate that all numbers greater than 4 are also included in the solution set.

3. Final Answer

u4u \ge 4
