Answer:

Step-by-step explanation:
In this problem, we are expected to write/express the given statement in algebra notation. that is using mathematical expression letters and symbols to express word problem
Hence: nine times the difference of 5 and y
1. the difference of 5 and y= (5-y)
2. 9*(5-y)
Hence the expression is given as 
Answer:

Hello!</h2>
The answer is:
Center: (1,-2)
Radius: 4 units.
<h2>
Why?</h2>
To solve the problem, using the given formula of a circle, we need to find its standard equation form which is equal to:

Where,
"h" and "k"are the coordinates of the center of the circle and "r" is its radius.
So, we need to complete the square for both variable "x" and "y".
The given equation is:

So, solving we have:



Now, we have that:

So,
Center: (1,-2)
Radius: 4 units.
Have a nice day!
