If the lines (9x+2y=18) and (27x+my=55) are distinct parallel lines, what will be the value of (m)?यदि (9x+2y=18) और (27x+my=55) की रेखाएं समांतर अलग-अलग हों, तो (m) का मान क्या होगा?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (6)(6)
For parallel lines, (\frac{9}{27}=\frac{2}{m}), so (m=6). Since (\frac{18}{55}\neq\frac{1}{3}), the lines are not coincident.समांतर के लिए (\frac{9}{27}=\frac{2}{m}), इसलिए (m=6)। क्योंकि (\frac{18}{55}\neq\frac{1}{3}), रेखाएं संपाती नहीं हैं।
