Dora wrote the equation of the circle in the center radius form as (x − p)2 + (y − q)2 = 16. The value of p + q is _____.
Hint: The point \((p,q)\) is the center of the circle. (Why is that?)
because it's the radius?
i have no idea. can i have another hint maybe?
Well, knowing \((p,q)\) is the center of the circle is enough for you to figure this out. The general form of the circle \(x^2+y^2=r^2\) becomes your equation when you translate it right by \(p\) units and up \(q\) units. (Then, separately, applying the right value of radius \(r\)).
and the answer is . . .:/ @yankeyglee
@snorl4x can you help me with this
