Question

for which value of p,will the lines represented by the following pair of linear equation be parallel 3x-y-=0,6x-2y-p=0​

Answer 1

Answer:

p belongs to R

Step-by-step explanation:

as solpe of both the lines are equal

so they are parallel

in fact parallel line only depends on slopes not on the constant term..

Answer 2

Answer:

P can be any value except 10

Step-by-step explanation:

a1 = 3 , b1 = -1 , c = -5

a1 = 3 , b1 = -1 , c = -5a2 = 6 , b2 = -2 , c2 = -p

Now,

We know that parallel line indicates that

a1 / a2 = b1 / b2 ≠ c1 / c2

a1 / a2 = 3/6 = 1/2

b1 / b2 = -1/-2 = 1/2

C1 / c2 = -5/-p = 5/p

b1 C1

— ≠ —

b2 c2

1 5

— ≠ —

2 p

By cross multiplying ,

p≠10

Therefore, p can be any no. but not 10.
