No, I won't show you the solution, but I will show youhowto solve it yourself. If you were given a problem like this, you are presumed to have learned the formula for coordinates of a centroid:

If is the centroid of region R then

where "dA" is the differential of area for the region (so the denominator is just its area), dxdy in the case of Cartesian coordinates as here.

In particular, for the region between the graphs of and [maht]y= 2x+ 3[/tex], the centroid is given by

In both cases, the denominator reduces to
