Answer 1

To solve the inequality \(\frac{x}{3} \geq -1\), you can follow these steps:

1. Multiply both sides by 3 (since 3 is a positive number, the direction of the inequality will not change):

   \[ x \geq -3 \]

Now, you have the solution \(x \geq -3\).

Part 1: Fill in the response

The response can be completed as follows:

\(x\) greater than or equals \(-3\).

Graphing the solution

To graph the solution \(x \geq -3\):

• Draw a number line.
• From \(-3\), draw a solid or closed circle indicating that \(-3\) is included in the solution (because it is greater than or equal to).
• Shade all values to the right of \(-3\) to indicate that all numbers greater than \(-3\) are included in the solution.

Checking your solution

To check your solution, you can test a few values:

• Test value 0 (which is greater than -3): \[ \frac{0}{3} = 0 \quad \text{and} \quad 0 \geq -1 \quad \text{(true, so the solution is correct)} \]

• Test value -4 (which is less than -3): \[ \frac{-4}{3} = -\frac{4}{3} \quad \text{and} \quad -\frac{4}{3} \geq -1 \quad \text{(false, so it does not satisfy the inequality)} \]

From these tests, we confirm that the solution \(x \geq -3\) is correct.
