Step-by-step explanation:
We know that if (h,k) is the center of any circle and whose radius is = r then its equation is :

Given, the equation of circle

By comparing, we will get,
h = -2
k = 3
So, center of the circle is ( -2,3)

Answer:
The total value of the given expression is 12.
Step-by-step explanation:
(-2 + 1)² + 5(12 ÷ 3) - 9
First, do the expressions within the parentheses.
(-1)² + 5(4) - 9
Next, simplify the exponents.
1 + 5(4) - 9
Next, multiply 5 by 4.
1 + 20 - 9
Add 1 and 20 together.
21 - 9
Subtract 9 from 21.
12
So, the final answer to this equation is 12.
Table:
y = x²
can also be written as: f(x) = x²
Plug in each x value and calculate the output:
f(-4) = (-4)² = 16
f(-3) = (-3)² = 9
f(-2) = 4
f(-1) = 1
f(-
) = 
f(0) = 0
f(
) = 
f(1) = 1
f(2) = 4
f(3) = 9
f(4) = 16
