Question

Edith must read for a minimum of 20 minutes.

Write an inequality to represent each situation. Then, graph the solution.

Answer 1

The required inequality is:
`20\leq E` or
`E\geq 20E`

The graph is shown in figure.

Explanation:

Consider the provided information.

Edith must read for a minimum of 20 minutes.

Let the number of minutes is represented by x.

Edith must read minimum of 20 minutes that the value of x can be 20 or greater than it.

Thus, the required inequality is:

`20\leq E` or
`E\geq 20E`

Now draw the graph of the inequality.

Use a dot or close circle to represents ≤ or ≥.

The value of E is greater than or equal to 20 and the required graph is shown in figure.
