Question

the pairs of line represented by the equation 3x-6y=6 and 6x +KY =10 will be parallel if k is​

Answer 1

Step-by-step explanation:

3x- 6y=6 , 6x+ky = 10

3x-6y =6 (i)

6x+ky=10 (ii)

Multiplying equation i & ii

6x-12 y = 12 (iii)

subtracting equation (ii) by (iii)

6x - 12y - 12 =0

6x+ ky - 10 =10

________________

12ky-22

12y -22=k

y=10

putting value of Y in equation (iii)

6x+12× 10 = 12

6x-120 =12

6x+ky = 10

6x- 120 -12=0

6x+ky -10 =0

_____________

-120- 22=k

K=98.

so, ans is k= 98..
