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.
The line is parallel to the bisector of the 1st and 3rd quadrants
except it is shifted down 2 units:
Since we're considering the area below the graph (not included), the inequality is
