PLEASE HELP!!!!!!!!!! dora wrote the equation of the circle in the center radius form as (x - p)² + (y - q)² = 16. what is the value of p+q?

But if you only have the radius, the center point could be anywhere on the point o-o
OpenStudy (anonymous):
does this help?
OpenStudy (anonymous):
verymuch.
OpenStudy (anonymous):
the answer is 6 because 3+3=6. Ask me if you have questions.
OpenStudy (anonymous):
I do umm how did you get 3+3=6?

It's so obvious ;)
OpenStudy (anonymous):
im still confused
OpenStudy (anonymous):
well, if you look at the graph, the center point is at (3,3)
OpenStudy (anonymous):
yeah but shouldn't it match to 16?
OpenStudy (anonymous):
p and q are the coordinates for the center in x and y

16 is just the indication of r^2 which means that the radius is 4
OpenStudy (anonymous):
Ok
OpenStudy (anonymous):
but you already have that in the graph
OpenStudy (anonymous):
thats what they gave me
OpenStudy (anonymous):
From the center, draw the 2 lines perpendicularly to x axis, y axis!
It called coordinate ( y, p)

=> y + p = ...
OpenStudy (anonymous):
You're no fun :P
OpenStudy (anonymous):
so whats the answer here...
