Question: Which absolute value inequality represents the intervals $x \leq -4$ or $x \geq 10$?
A) $|x - 3| \leq 7$
B) $|x + 3| \geq 7$
C) $|x - 3| \geq 7$
D) $|x - 7| \geq 3$
1. **State the problem:** We want to find which absolute value inequality corresponds to the intervals $x \leq -4$ or $x \geq 10$.
2. **Recall the absolute value inequality form:**
For $|x - a| \geq b$, the solution is $x \leq a - b$ or $x \geq a + b$.
3. **Check each option:**
- A) $|x - 3| \leq 7$ means $-7 \leq x - 3 \leq 7$ which simplifies to $-4 \leq x \leq 10$. This is the interval between $-4$ and $10$, not outside.
- B) $|x + 3| \geq 7$ means $x + 3 \leq -7$ or $x + 3 \geq 7$, which simplifies to $x \leq -10$ or $x \geq 4$. This does not match the intervals.
- C) $|x - 3| \geq 7$ means $x - 3 \leq -7$ or $x - 3 \geq 7$, which simplifies to $x \leq -4$ or $x \geq 10$. This matches exactly.
- D) $|x - 7| \geq 3$ means $x - 7 \leq -3$ or $x - 7 \geq 3$, which simplifies to $x \leq 4$ or $x \geq 10$. This is close but the left interval is $x \leq 4$, not $x \leq -4$.
4. **Conclusion:** The correct inequality is option C) $|x - 3| \geq 7$.
**Final answer:** $|x - 3| \geq 7$
