The differential equation is
Step-by-step explanation:
From the question we are told that
The number of students are
The number of student that have contracted the flu is x(t)
The number of student that don't have the flu is mathematically represented as
The rate at which the disease spread is proportional to the number of interactions between students with the flu and students who have not yet contracted it, which can be mathematically represented as
=>
Answer:
a.x=4
b.x=4
c.(b)
Step-by-step explanation:
We are given that
a. First we adding x on both sides we get
Now, subtract 5 on both sides we get
b.
We are subtracting 9 from both sides we get
We can solve equation both approach a and b
But I prefer (b) because in approach (b)
There are only 3 step in which we can get answer but in approach (a) we can get answer in 4 steps .
Hence, I prefer approach (b)
