For which value will the lines (4x+ay=16) and (8x+10y=35) be distinct and parallel?किस मान पर (4x+ay=16) और (8x+10y=35) की रेखाएं समांतर अलग-अलग होंगी?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (a=5)(a=5)
For parallel lines, (\frac{4}{8}=\frac{a}{10}), so (a=5). Since (\frac{16}{35}\neq\frac{1}{2}), they will not be coincident.समांतर के लिए (\frac{4}{8}=\frac{a}{10}), इसलिए (a=5)। चूंकि (\frac{16}{35}\neq\frac{1}{2}), वे संपाती नहीं होंगी।
