Answer:
The feasible region is unbounded which is the shaded portion in the graph.
Step-by-step explanation:
Given that, the number of hours Jessie works as a teacher and tutor is y and x respectively, which can't be negative.
So, 
y\ge0\;\cdots(ii)
She works at least 36 hours a week.


She works as a teacher for al least twice the number of hours she works as a tutor.

The boundary of the inequalities from equations (i), (ii), (iii), and (iv) are
and
.
The feasible region is the shaded portion which is the unbounded region as shown in the graph. Any point P(x,y) from the feasible region will satisfies all the constraints.
