संख्या रेखा पर (x>4) को कैसे दिखाया जाएगा?

How will (x>4) be shown on a number line?

Explanation opens after your attempt
Correct Answer

A. (4) पर खाली गोला और दाईं ओर रेखाOpen circle at (4) and line to the right

Step 1

Concept

In (>), the boundary number is not included, so use an open circle. In exams, decide direction from the inequality sign.

Step 2

Why this answer is correct

The correct answer is A. (4) पर खाली गोला और दाईं ओर रेखा / Open circle at (4) and line to the right. In (>), the boundary number is not included, so use an open circle. In exams, decide direction from the inequality sign.

Step 3

Exam Tip

(>) में सीमा संख्या शामिल नहीं होती इसलिए खाली गोला लगेगा। परीक्षा में दिशा चिन्ह से तय करें।

असमानता \(x\ge -2\) का संख्या रेखा पर सही निरूपण कौन-सा है?

Which is the correct number line representation of the inequality \(x\ge -2\)?

Explanation opens after your attempt
Correct Answer

C. (-2) पर बंद बिंदु और दाईं ओर रेखाClosed dot at (-2) and ray to the right

Step 1

Concept

The sign \(\ge\) includes equality so the dot is closed. In exams always check the direction toward greater values.

Step 2

Why this answer is correct

The correct answer is C. (-2) पर बंद बिंदु और दाईं ओर रेखा / Closed dot at (-2) and ray to the right. The sign \(\ge\) includes equality so the dot is closed. In exams always check the direction toward greater values.

Step 3

Exam Tip

चिह्न \(\ge\) में बराबरी शामिल होती है इसलिए बंद बिंदु लगेगा। परीक्षा में दिशा हमेशा बड़े मानों की ओर देखें।

यदि संख्या रेखा पर (3.5) पर खुला बिंदु है और रेखा बाईं ओर जाती है तो कौन-सी असमानता बनेगी?

If the number line has an open dot at (3.5) and the ray goes to the left then which inequality is formed?

Explanation opens after your attempt
Correct Answer

D. (x<3.5)

Step 1

Concept

The open dot shows that (3.5) is not included and the left direction shows smaller values. In exams write a strict inequality for an open dot.

Step 2

Why this answer is correct

The correct answer is D. (x<3.5). The open dot shows that (3.5) is not included and the left direction shows smaller values. In exams write a strict inequality for an open dot.

Step 3

Exam Tip

खुला बिंदु बताता है कि (3.5) शामिल नहीं है और बाईं दिशा छोटे मान दिखाती है। परीक्षा में खुले बिंदु के लिए सख्त असमानता लिखें।

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।

कौन-सा अंतराल संख्या रेखा पर (0) से (6) तक खुले सिरों वाला भाग दिखाता है?

Which interval shows the part from (0) to (6) with open endpoints on the number line?

Explanation opens after your attempt
Correct Answer

C. ((0,6))

Step 1

Concept

Open endpoints mean both (0) and (6) are not included. In exams write ((0,6)) for two open dots.

Step 2

Why this answer is correct

The correct answer is C. ((0,6)). Open endpoints mean both (0) and (6) are not included. In exams write ((0,6)) for two open dots.

Step 3

Exam Tip

खुले सिरों का अर्थ है कि (0) और (6) दोनों शामिल नहीं हैं। परीक्षा में दोनों खुले बिंदुओं के लिए ((0,6)) लिखें।

Explanation opens after your attempt
Correct Answer

B. (-3)

Step 1

Concept

(-4) is not included, so the next integer is (-3). In exams, take the integer after an open left endpoint.

Step 2

Why this answer is correct

The correct answer is B. (-3). (-4) is not included, so the next integer is (-3). In exams, take the integer after an open left endpoint.

Step 3

Exam Tip

(-4) शामिल नहीं है इसलिए अगला पूर्णांक (-3) है। परीक्षा में खुले बाएँ बिंदु के बाद वाला पूर्णांक लें।

संख्या रेखा पर (|x|<3) का अंतराल रूप क्या है?

What is the interval form of (|x|<3) on the number line?

Explanation opens after your attempt
Correct Answer

A. ((-3,3))

Step 1

Concept

(|x|<3) means the distance of (x) from (0) is less than (3). In exams, when distance is less, take the middle part.

Step 2

Why this answer is correct

The correct answer is A. ((-3,3)). (|x|<3) means the distance of (x) from (0) is less than (3). In exams, when distance is less, take the middle part.

Step 3

Exam Tip

(|x|<3) का अर्थ (x) की (0) से दूरी (3) से कम है। परीक्षा में दूरी कम हो तो बीच का भाग लें।

Step 2

Why this answer is correct

The correct answer is A. (x>7) इसलिए (7) पर खाली गोला और दाईं ओर / (x>7), so open circle at (7) and right side. Multiplying both sides by (3) gives (x-1>6), so (x>7). In exams, find the boundary first and then choose circle and direction.
