The value of A is 1, D is 0, E is -2 and F is 0.
Step-by-step explanation:
The given equation is
...(1)
The standard form of the circle is
Where, (h,k) is the center of the circle and r is the radius.
It can be written as
....(2)
On comparing (1) and (2) we get.
Therefore the value of A is 1, D is 0, E is -2 and F is 0.

In order to determine the number of pens present in the container, we need to set up equations from the given in the problem statement. We do as follows:
let x the number of pencils
y the number of pens
From the statement, 9 more pencils then pens in a container,
x = y + 9
From the statement, there are 25 writing utensils in the container in all,
x + y = 25
We use substitution method to calculate for x and y,
y + 9 + y = 25
2y = 16
y = 8
x = 17
Therefore, there are 8 pens in the container and 17 pencils.
