Which point is exactly midway between (1.8) and (2.6) on the number line?
C. (2.2)
बीच का बिंदु \(\frac{1.8+2.6}{2}=2.2\) है। परीक्षा में ठीक बीच का अर्थ औसत होता है। / The middle point is \(\frac{1.8+2.6}{2}=2.2\). In exams, exactly midway means average.

On the number line, (x) is at a distance (1.5) from (4) and (x<4). What is (x)?
A. (2.5)
क्योंकि (x<4), इसलिए (x=4-1.5=2.5) होगा। परीक्षा में दूरी के साथ दिशा की शर्त भी पढ़ें। / Since (x<4), (x=4-1.5=2.5). In exams, read the direction condition along with distance.

On the number line, (y) is (3.25) units to the right of (-2). What is (y)?
A. (1.25)
दाईं ओर जाने पर (y=-2+3.25=1.25) है। परीक्षा में दिशा के अनुसार संख्या जोड़ें या घटाएं। / Moving right gives (y=-2+3.25=1.25). In exams, add or subtract according to direction.

Which number is not between (-1) and (0) on the number line?
C. \(-\frac{5}{4}\)
\(-\frac{5}{4}=-1.25\), जो (-1) से बाईं ओर है। परीक्षा में ऋणात्मक भिन्न को दशमलव में बदलकर जांच सकते हैं। / \(-\frac{5}{4}=-1.25\), which is to the left of (-1). In exams, convert negative fractions into decimals to check.

Which point lies between (-2) and (-1) on the number line?
B. \(-\frac{3}{2}\)
\(-\frac{3}{2}=-1.5\), इसलिए यह (-2) और (-1) के बीच है। परीक्षा में ऋणात्मक भिन्न का दशमलव रूप मदद करता है। / \(-\frac{3}{2}=-1.5\), so it lies between (-2) and (-1). In exams, the decimal form of a negative fraction helps.

At which points will the solutions of \(x^2-25=0\) be found on the number line?
C. (-5) और (5)(-5) and (5)
\(x^2=25\) से \(x=\pm5\) मिलता है। परीक्षा में वर्ग लेने पर दोनों चिह्नों के हल मिलते हैं। / From \(x^2=25\), \(x=\pm5\). In exams, squaring gives solutions with both signs.

If (p(x)=(x-2)(x+3)), which zeros will appear on the number line?
C. (2) और (-3)(2) and (-3)
(x-2=0) से (2) और (x+3=0) से (-3) मिलता है। परीक्षा में हर गुणनखंड को (0) के बराबर रखें। / From (x-2=0) we get (2), and from (x+3=0) we get (-3). In exams, set each factor equal to (0).

What are the zeros of (p(x)=(2x-1)(x+4)) on the number line?
A. \(\frac{1}{2}\) और (-4)\(\frac{1}{2}\) and (-4)
(2x-1=0) से \(x=\frac{1}{2}\) और (x+4=0) से (x=-4) मिलता है। परीक्षा में प्रत्येक रैखिक गुणनखंड अलग हल करें। / From (2x-1=0), \(x=\frac{1}{2}\), and from (x+4=0), (x=-4). In exams, solve each linear factor separately.

A. \(0,\frac{1}{2},\sqrt{2},2\)
\(\sqrt{2}\) लगभग (1.414) है, इसलिए क्रम \(0,\frac{1}{2},\sqrt{2},2\) है। परीक्षा में बढ़ता क्रम बाएं से दाएं होता है। / \(\sqrt{2}\) is about (1.414), so the order is \(0,\frac{1}{2},\sqrt{2},2\). In exams, increasing order is from left to right.

On the number line, which point is to the right, \(x=-\sqrt{2}\) or \(y=-\frac{3}{2}\)?
A. (x)
\(-\sqrt{2}\) लगभग (-1.414) है और \(-\frac{3}{2}=-1.5\), इसलिए (x) बड़ा है। परीक्षा में ऋणात्मक संख्याओं में कम दूरी वाला बिंदु दाईं ओर हो सकता है। / \(-\sqrt{2}\) is about (-1.414) and \(-\frac{3}{2}=-1.5\), so (x) is greater. In exams, for negative numbers, the point with smaller distance from (0) may lie to the right.
