The pairs of line represented by the equation 3x-6y=6 and 6x +KY =10 will be parallel if k is |
|
Answer» 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.. |
