5
algebraWhich inequality represents all numbers that are more than 5 units away from 0?
A
B
or
C
D
Correct Answer: B
Choice B is the correct answer. Distance from zero on a number line involves both positive and negative directions.
- Understanding: "More than 5 units from 0" means farther than 5 in EITHER direction
- Positive side: Numbers (like 6, 7, 100)
- Negative side: Numbers (like -6, -7, -100)
- Combine with OR: or
?�� Strategic Tip: Distance problems often use "or" to combine two separate regions on the number line.
Choice A is incorrect because it only captures positive numbers beyond 5, missing the negative side. Choice C is incorrect because this represents numbers WITHIN 5 units of 0, the opposite of what we want. Choice D is incorrect because includes 5 itself (which is exactly 5 units away, not more than), and misses negative numbers.
