The graph of the region is attached. The coordinates of the centroid are (5/3, 1).
The coordinates of the centroid are found by averaging the coordinates of the region;
Oₓ = (Aₓ+Bₓ+Cₓ)/3 = (0+1+4)/3 = 5/3
O(y) = (A(y) + B(y) + C(y)) = (0+3+0)/3=3/3=1

What is the result of isolating y^2 in the equation below (x-2)^2+y^2=64?
Solution:
We want to isolate from the equation
To isolate , we must try to get
alone
So, We must subtract from both sides
