Answer:
Since L.H.S = R.H.S = 0, for both and , y₁ and y₂ both satisfy the equation y" - y = 0 and are thus solutions to the differential equation.
Step-by-step explanation:
To check whether the given functions are solutions the given differential equation, we differentiate the functions and then insert it into the given equation.
So y" - y = 0 and
Substituting these values of y and y" into the left hand side of the equation, we have
y" - y
Since L.H.S = R.H.S
So is a solution of the differential equation.
When
Substituting y and y" into the left hand side of the equation, we have
y" - y
Since L.H.S = R.H.S
So, is a solution of the differential equation.

Step-by-step explanation:
Answer:
There are 700 books in Library Collections.
Step-by-step explanation:
Given:
Number of historical books = 70
The equation used to find the totals number of books in library collection.
where b⇒ Total number of books in library collections.
We need to find the Total number of books in library collections.
Solution:
Now by solving the above equation we get;
First we will multiply both side by 10 we get;
Hence there are 700 books in Library Collections.
