Question

solve for k for infinitely many sol..
FAST PLEASE....

Answer 1

Answer:

Step-by-step explanation:

Condition required is

a1/a2=b1/b2=c1/c2

So, 10/20=-(k-5)/-k

1/2=-k+5/-k

-2k+10=-k

10=-k+2k

10=k

HOPE U WILL GET!!

Answer 2

let the infinitely ratio

a1=10

a2=20

b1=5

b2=10

c1=-(R-5)

c2=-R
