Answer:
1: 11b(exponent of 2) +6b -9c
2: -11xy -9x -5x(exponent of 2)y
Step-by-step explanation:
Let's do

Release k for some while
If
So
So vertical asymptote is at origin now
It mentioned that it's at x=-5 so we need to change x


- Vertical asymptote at x=-5
Now
- for k=0 horizontal asymptote at origin
But it's given
Same put y=12 in place of k
