Lets find where the intersection point would be, if they were lines:

#y = -x+3#
#y = x-2#

#x-2=-x+3#

#2x=5#

#x = 5/2#

The solutions are a region below but not including the ray

#y = -x+3; x < 5/2#

and above and including the ray

#y = x-2;x < 5/2#

Here is a graph of the two inequalities:

The solution is the magenta region.
