Answer 1

Question 1: Correct Order of Steps to Solve the Inequality

To solve the inequality $4x-9\ge -21$, we follow these steps:

1. Step 1: Add 9 to both sides of the inequality. $$4x-9+9\ge -21+9$$ This simplifies to: $$4x\ge -12$$

2. Step 2: Divide both sides by 4. $$\frac{4x}{4}\ge \frac{-12}{4}$$ This simplifies to: $$x\ge -3$$

3. Step 3: State the solution. $$x\ge -3$$

Question 2: Number Line Representation of the Solution

The solution $x\ge -3$ can be represented on a number line as follows:

• A filled (or closed) dot at -3 to indicate that -3 is included in the solution.
• A line extending to the right from -3 to indicate all values greater than -3 are included.

If you have options for the number line, you should look for a representation matching this description.
