Question

5x-7y-5=0 2x+ky-1=0 k ka maan

Answer 1

Answer:

K ≠ - 14/5

Step-by-step explanation:

Given equations are

5x-7y-5=0

2x+ky-1=0

a1 = 5 b1 = - 7 c1 = - 5

a2 = 2 b2 = k c2 = - 1 ( - gets cancelled in c terms being same signs)

So they are intersecting lines satisfying the condition a1/a2 ≠ b1/b2

5/2 ≠ - 7/k ( by cross Multiply we obtain)

5k ≠ - 14

K ≠ - 14/5 ( Therefore k can be any other value except for - 14/5
