Solve for xx and graph the solution on the number line below.

Question

4, x, is greater than or equal to, 16
4x≥
16

Answer 1

To solve for x, divide both sides of the inequality by 4:
x ≥ 4

We can graph this on the number line by putting a closed circle on 4 and shading to the right to indicate that x is greater than or equal to 4:

```
<-------------------●=====>
-3 0 4 8 12 16 20
```

The closed circle on 4 indicates that x can be equal to 4, and the shading to the right shows that x can be any value greater than 4.
