this is what I would come up with because.
y=the number of people infected
x=the number of days that have passed
<span>(-5/6) + c = (-11/12)
c=-11\12+5\6
c=19\12 or 1 7\12</span>
Here all three are the factor. {a+b} will be the sum and 1/2 is the term
Hopefully i am right
All the best !!
The answer to this problem is 9 hopefully this helps you!
