Question: 3. Which inequality is graphed on the number line?
Values of x
a. $x \leq -3$
b. $x \geq -3$
c. $x < -3$
d. $x > -3$
e. $x = -3$
1. **Problem:** Identify the inequality graphed on a number line with an open circle at $-3$ and a shaded ray extending to the right.
2. **Understanding the graph:**
- An open circle at $-3$ means $x$ is not equal to $-3$.
- A shaded ray extending to the right means $x$ is greater than $-3$.
3. **Inequality options:**
- $x \leq -3$ means $x$ is less than or equal to $-3$ (closed circle, left shading).
- $x \geq -3$ means $x$ is greater than or equal to $-3$ (closed circle, right shading).
- $x < -3$ means $x$ is less than $-3$ (open circle, left shading).
- $x > -3$ means $x$ is greater than $-3$ (open circle, right shading).
- $x = -3$ means only the point $-3$ (closed circle).
4. **Conclusion:** The graph shows an open circle at $-3$ and shading to the right, so the inequality is:
$$x > -3$$
**Final answer:** d. $x > -3$
