Answer: 
Step-by-step explanation:
Given the equation:
You must solve for "x" to find its value.
You can follow these steps:
- Add 
to both sides of the equation:
- Subtract 9 from both sides of the equation:
- Divide both sides of the equation by 8. Then you get:
Answer:
About 72%

a. The center of the circle will be the coordinate point of the marked point inside the circle.
center: (3,-5)
The radius is the distance between the center and any point on the circle.
radius: 4 units
b. standard form for circles: (x-h)²+(y-k)²=r² where (h,k) is the center
standard form: (x-3)²+(y+5)²=16
c. Simplify equation in standard form to get general form.
(x-3)²+(y+5)²=16
x²-6x+9+y²+10y+25=16
general form: x²+y²-6x+10y+18=0
