The equation of the circle shown is:
<h3>What is the equation of a circle?</h3>
The equation of a circle of center 
and radius r is given by:
From the graph, it can be seen that the center of the circle is (0,0), thus 
and the radius is of r = 10, hence the equation is:

<h3>
Answer:</h3>
- A) p = 5, one solution
- B) no solutions
- C) infinite solutions
<h3>
Step-by-step explanation:</h3>
A) Add 19-5p to each side of the equation:
... 10 = 2p
... 5 = p . . . . . divide by the coefficient of p
B) Subtract 5p from both sides of the equation:
... -9 = -19 . . . . . there is <em>no value of p</em> that will make this true. (No solution.)
C) Subtract 5p from both sides of the equation:
... -9 = -9 . . . . . this is true for <em>every value of p</em>. (Infinite solutions.)
