| Question 13 |
What is the value of k for which the following system of equations has no solution:
2x – 8y = 3 and kx + 4y = 10
2x – 8y = 3 and kx + 4y = 10
| -2 | |
| 1 | |
| -1 | |
| 2 |
Question 13 Explanation:
2X – 8Y = 3
KX + 4Y = 10
(a1 / a2) = (b1 / b2) ≠ (c1/c2)
2/K = (-8/4)
K= -1
KX + 4Y = 10
(a1 / a2) = (b1 / b2) ≠ (c1/c2)
2/K = (-8/4)
K= -1
Correct Answer: C
Question 13 Explanation:
2X – 8Y = 3
KX + 4Y = 10
(a1 / a2) = (b1 / b2) ≠ (c1/c2)
2/K = (-8/4)
K= -1
KX + 4Y = 10
(a1 / a2) = (b1 / b2) ≠ (c1/c2)
2/K = (-8/4)
K= -1
