Write an inequality represented by the graph.

Short Answer

Expert verified

The inequality x鈮�-5 represents the given graph.

Step by step solution

01

Step 1. Given Information.

Graph of an inequality:

02

Step 2. Calculation.

We have been given a number line inequality. We can see the arrow on the number line points to all values greater than or equal to -5.

We can also see that the point at -5 is filled in, so our given graph represents everything greater than or -5.

Upon representing our given information in an inequality, we will get:

x鈮�-5

Therefore, the inequality x鈮�-5 represents our given graph.

03

Step 3. Conclusion.

The inequality x鈮�-5 represents the given graph.
