असमानता \( 5x+2\le 3x-6 \) का संख्या रेखा पर सही रूप कौन सा है?

Which is the correct number-line form of \( 5x+2\le 3x-6 \)?

Explanation opens after your attempt
Correct Answer

A. \( x\le -4 \), बंद बिंदु ( -4 ), बाईं ओर छाया\( x\le -4 \), closed at ( -4 ), shaded left

Step 1

Concept

Simplification gives \( 2x\le -8 \), so \( x\le -4 \). The sign \( \le \) includes the boundary point.

Step 2

Why this answer is correct

The correct answer is A. \( x\le -4 \), बंद बिंदु ( -4 ), बाईं ओर छाया / \( x\le -4 \), closed at ( -4 ), shaded left. Simplification gives \( 2x\le -8 \), so \( x\le -4 \). The sign \( \le \) includes the boundary point.

Step 3

Exam Tip

सरलीकरण से \( 2x\le -8 \), अतः \( x\le -4 \)। \( \le \) सीमा बिंदु को शामिल करता है।

असमानता (5x-2>18) के हल का संख्या रेखा रूप कौन-सा है?

Which number line form represents the solution of (5x-2>18)?

Explanation opens after your attempt
Correct Answer

A. (4) पर खुला बिंदु और दाईं ओर रेखाOpen dot at (4) and ray right

Step 1

Concept

Solving gives (x>4) so (4) is not included. In exams first find the boundary and then decide the direction.

Step 2

Why this answer is correct

The correct answer is A. (4) पर खुला बिंदु और दाईं ओर रेखा / Open dot at (4) and ray right. Solving gives (x>4) so (4) is not included. In exams first find the boundary and then decide the direction.

Step 3

Exam Tip

हल करने पर (x>4) मिलता है इसलिए (4) शामिल नहीं है। परीक्षा में पहले boundary निकालें फिर direction तय करें।

असमानता \(2x-3\ge 7\) के हल को संख्या रेखा पर दिखाने के लिए सही विकल्प कौन-सा है?

Which option correctly shows the solution of \(2x-3\ge 7\) on the number line?

Explanation opens after your attempt
Correct Answer

A. (5) पर बंद बिंदु और दाईं ओर रेखाClosed dot at (5) and ray to the right

Step 1

Concept

Solving gives \(x\ge 5\) so (5) is included and the ray goes right. In exams simplify the inequality first then draw the number line.

Step 2

Why this answer is correct

The correct answer is A. (5) पर बंद बिंदु और दाईं ओर रेखा / Closed dot at (5) and ray to the right. Solving gives \(x\ge 5\) so (5) is included and the ray goes right. In exams simplify the inequality first then draw the number line.

Step 3

Exam Tip

हल करने पर \(x\ge 5\) मिलता है इसलिए (5) शामिल है और रेखा दाईं ओर जाएगी। परीक्षा में पहले असमानता सरल करें फिर संख्या रेखा बनाएं।

Explanation opens after your attempt
Correct Answer

A. \(x\geq \frac{13}{11}\)

Step 1

Concept

Multiplying by (14) gives \(42-4x+10\leq 7x+28\). Thus \(24\leq 11x\) and \(x\geq \frac{24}{11}\).

Step 2

Why this answer is correct

The correct answer is A. \(x\geq \frac{13}{11}\). Multiplying by (14) gives \(42-4x+10\leq 7x+28\). Thus \(24\leq 11x\) and \(x\geq \frac{24}{11}\).

Step 3

Exam Tip
