We have been given an equation of circle . We are asked to find the center and radius of the circle.
First of all, we will write equation of circle is standard form , where center of circle is at point (h,k) and radius is r.
Let us complete the square for both x and y.
Adding half the square of coefficient of x and y term, we will get:
Therefore, the center of the circle is and radius is 4 units.

Answer:
$2960
Step-by-step explanation:
Lily has two times as much money invested in 8% stocks,
As she has in bonds paying 6%
Let the money invested in 8% stocks be 2x dollars,
The money in bonds paying 6% is then x dollars.
So, $2x() + $x() = $325.6
$0.16x + $0.06x = $325.6
$0.22x = $325.6
x = $1480
The money she has invested in stocks is 2x = 2 × $1480 = $2960
What does that even mean you need a picture to really understand
You could do 7 x 40 and take off (7 x 2)
or 5 x 38 and add (2 x 38).
