Question

fund the value of k for which the lines (k+1)x +3ky+15=0and 5x+5=0​

Answer 1

Answer:

(k+1)x+3ky+15=0

5x +0.y +5=0

we can find the value of k by using formula

a1/a2=b1/b2=c1/c2

here a1=(k+1),a2=5

b1=3k. ,b2=1

c1=15. ,c2=5

now put these values in the above formula we get

k+1/5=3k/1=(15/5)or3

k+1/5=3,3k/1=3

k+1=3*5,k=3/3

k=15-1,k=1

k=14,1

so the value of k will be(14,1)
