find the value of k for which the pair of linear equations 3x+ky+2y=0,6x-8y+7=0 represent the parallel lines |
|
Answer» Step-by-step explanation: 3x+(k+2)y=0.............................[1] 6x-8y+7=0..................................[2] here a1=3 , a2=6 b1=k+2, b2=-8 c1=0 , c2=7 condition for PARALLEL lines a1/a2 is equal to b1/b2 is not equal to c1/c2 a1/a2=3/6=1/2 b1/b2=k+2/-8 c1/c2=0/7=0 by condition 1/2=- k+2/8 -k-2=4 -k=6 k=-6 hope it helps please MARK as BRAINLIEST |
