\( 9\le 4x+1\le 17 \) का संख्या रेखा पर सही निरूपण कौन सा है?
Which is the correct number-line representation of \( 9\le 4x+1\le 17 \)?
Explanation opens after your attempt
B. ( [2,4] )
Concept
Solving gives \( 8\le 4x\le 16 \), so \( 2\le x\le 4 \). Since both signs include equality, both endpoints are closed.
Why this answer is correct
The correct answer is B. ( [2,4] ). Solving gives \( 8\le 4x\le 16 \), so \( 2\le x\le 4 \). Since both signs include equality, both endpoints are closed.
Exam Tip
हल करने पर \( 8\le 4x\le 16 \), इसलिए \( 2\le x\le 4 \)। दोनों \( \le \) होने से दोनों सिरे बंद होंगे।
