Answer:

#y >= 9#

Explanation:

As the inequalities are currently stated:
#{(y=2x+3,),(-1<=x>=4,"note that this simply implies: " x>=4):}#

from this it follows that
#y >=2xx(4)+1#

#rarr y >= 9#

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Check that the second inequality was not intended to be
#color(white)("XXX")-1 <=x color(red)(<=) 4#
