यदि \(x\in\mathbb{Z}\) और \(|x+2|\le 5\), तो संख्या रेखा पर कितने पूर्णांक बिंदु होंगे?

If \(x\in\mathbb{Z}\) and \(|x+2|\le 5\), how many integer points will be on the number line?

Explanation opens after your attempt
Correct Answer

C. (11)

Step 1

Concept

\(|x+2|\le5\) gives \(-7\le x\le3\), so there are (11) integers. In exams, count endpoints in a closed interval.

Step 2

Why this answer is correct

The correct answer is C. (11). \(|x+2|\le5\) gives \(-7\le x\le3\), so there are (11) integers. In exams, count endpoints in a closed interval.

Step 3

Exam Tip

\(|x+2|\le5\) से \(-7\le x\le3\), इसलिए कुल (11) पूर्णांक हैं। परीक्षा में closed interval में endpoints भी गिनें।
