What is the number line interval for the compound inequality \(1\le \frac{2x-3}{5}<3\)?

Explanation opens after your attempt
Correct Answer

B. ([4,9))

Step 1

Concept

Solving gives \(5\le 2x-3<15\) and then \(4\le x<9\). Therefore (4) is included but (9) is excluded.

Step 2

Why this answer is correct

The correct answer is B. ([4,9)). Solving gives \(5\le 2x-3<15\) and then \(4\le x<9\). Therefore (4) is included but (9) is excluded.

Step 3

Exam Tip

हल करने पर \(5\le 2x-3<15\) और फिर \(4\le x<9\) मिलता है। इसलिए (4) शामिल है लेकिन (9) शामिल नहीं है।
