Graph the solution and write the set in interval notation.

Solve the inequality: [tex]\(-9 \leq 3t \leq 18\)[/tex]

Part 1 of 2:
The graph of the solution set is:

Part 2 of 2:
The solution set is written in interval notation as:



Answer :

Let's tackle the given inequality step by step:

### Analysis of the Inequality

The given compound inequality is:
[tex]\[ -9 \leq 31 \leq 18 \][/tex]

Here, we need to determine if there exists any value that satisfies both parts of the inequality simultaneously.

Step 1: Analyze the first part of the inequality.
[tex]\[ -9 \leq 31 \][/tex]
This is a true statement because [tex]\(-9\)[/tex] is less than [tex]\(31\)[/tex].

Step 2: Analyze the second part of the inequality.
[tex]\[ 31 \leq 18 \][/tex]
This is a false statement because [tex]\(31\)[/tex] is greater than [tex]\(18\)[/tex].

Since both parts of the inequality must be true for the inequality to hold true, and here one part is false, the combined inequality is invalid.

### Graphing the Solution Set

Given that the combined inequality does not hold true, there is no value [tex]\(x\)[/tex] that satisfies [tex]\( -9 \leq 31 \leq 18 \)[/tex]. Therefore, the solution set is empty.

On a number line, this would be represented by no shading or markings, as there are no valid values.

### Representing the Solution Set in Interval Notation

Since the inequality is invalid and there is no value that satisfies [tex]\( -9 \leq 31 \leq 18 \)[/tex]:
- The solution set is an empty set.

The interval notation for an empty set is:
[tex]\[ \emptyset \][/tex]
or
[tex]\[ () \][/tex]

### Summary

Part 1: The graph of the solution set is blank, indicating no values satisfy the inequality.

Part 2: The solution set in interval notation is:
[tex]\[ \emptyset \][/tex]
or
[tex]\[ () \][/tex]
