Class 11 Mathematics Linear Inequalities representation on number line Hard Level 46

संख्या रेखा पर (\(-\infty,-2]\cup[-2,5\)) को सरल interval में लिखें।

Write (\(-\infty,-2]\cup[-2,5\)) as a simplified interval on the number line.

Explanation opens after your attempt
Correct Answer

A. (\(-\infty,5\))

Step 1

Concept

The two intervals meet at (-2), and (5) is not included. In exams, merge touching intervals when the common endpoint is included.

Step 2

Why this answer is correct

The correct answer is A. (\(-\infty,5\)). The two intervals meet at (-2), and (5) is not included. In exams, merge touching intervals when the common endpoint is included.

Step 3

Exam Tip

दोनों intervals (-2) पर जुड़ते हैं और (5) शामिल नहीं है। परीक्षा में touching intervals को merge करें जब common endpoint included हो।
