1. | \[2x+3y=40\] \[6x+5y=10\] | A. | Coincident lines |
2. | \[2x+3y=40\] \[6x+9y=50\] | B. | Intersecting lines |
3. | \[2x+3y=10\] \[4x+6y=20\] | C. | Parallel lines |
A) 1-A, 2-B, 3-C
B) 1-B, 2-A, 3-C
C) 1-B, 2-C, 3-A
D) 1-C, 2-A, 3-B
Correct Answer: C
Solution :
[c] (1) \[\frac{2}{6}\ne \frac{3}{5}\] |
(2) \[\frac{2}{6}=\frac{3}{9}\ne \frac{40}{50}\] |
(3) \[\frac{2}{4}=\frac{3}{6}=\frac{10}{20}\] |
