\( -3\le 2x-1<9 \) को संख्या रेखा पर किस अंतराल से दिखाया जाएगा?
By which interval will \( -3\le 2x-1<9 \) be shown on the number line?
Explanation opens after your attempt
A. ( [-1,5) )
Concept
Solving gives \( -2\le 2x<10 \), so \( -1\le x<5 \). Preserve endpoint signs throughout the solution.
Why this answer is correct
The correct answer is A. ( [-1,5) ). Solving gives \( -2\le 2x<10 \), so \( -1\le x<5 \). Preserve endpoint signs throughout the solution.
Exam Tip
हल करने पर \( -2\le 2x<10 \), इसलिए \( -1\le x<5 \)। सीमा चिह्नों को अंत तक सुरक्षित रखें।
