Answer:
Step-by-step explanation:
General equation of circle is 
---------------------(1)
This circle passes through the given three points, (1,7) , (8,6) and (7,-1).
Substitute (1,7) in (1),
1 + 
=0
2g + 14f + c = -50 -------------(2)
Substitute (8,6) in (1),
16g + 12f + c = -100 -----------(3)
Substitute (7,-1) in (1),
14g - 2f + c = -50 ---------------(4)
Solving (2),(3) amd (4) simultaneously,
g = -4
f = -3
c = 0
Equation of circle is
The answer is p = 5.
Here are the steps I did.
1. Simplify 8p + 10p - p - 8p + 5 to 9p + 5 ( 9p + 5 = 50)
2. Subtract 5 from both sides ( 9p = 50 - 5)
3. Simplify 50 - 5 to 45 ( 9p = 45)
4. Divide both sides by 9 ( 45/9)
5. Simplify 45/9 to 5 ( p = 5)
