Question

If the lines given by 3x + 2ky = 2 and 2x+5y+1=0 are parallel, then find the value of k.​

Answer 1

Answer:

k = 15/4

Step-by-step explanation:

a1/a2 = b1/b2 That means the line is a parallel.

Therefore, a1 = 3      a2= 2                b1= 2k         b2= 5

Therefore, 3/2 = 2k/5

Therefore, 3 x 5 x 1/2 = 2k      (Solve this step or just write in notebook so you will understand well)

Therefore, 15/2 = 2k

Therefore, 15/2 x 1/2 = k            (Solve this step or just write in notebook so you will understand well)

Therefore, k = 15/4
