किस असमानता की संख्या रेखा पर ( -2 ) पर बंद बिंदु और ( 5 ) पर खुला बिंदु होगा तथा बीच में छाया होगी?
Which inequality will have a closed dot at ( -2 ), an open dot at ( 5 ), and shading between them on the number line?
Explanation opens after your attempt
Correct Answer
B. \( -2\le x<5 \)
Concept
( -2 ) is closed, so use \( \le \), and ( 5 ) is open, so use ( < ). Decide the left and right endpoint signs separately.
Why this answer is correct
The correct answer is B. \( -2\le x<5 \). ( -2 ) is closed, so use \( \le \), and ( 5 ) is open, so use ( < ). Decide the left and right endpoint signs separately.
Exam Tip
( -2 ) बंद है इसलिए \( \le \), और ( 5 ) खुला है इसलिए ( < )। बाईं सीमा और दाईं सीमा के चिन्ह अलग तय करें।
