Answer:
The graph in the attached figure
Two possible solutions are the point (10,10) and the point (4,8)
see the explanation
Step-by-step explanation:
Let
x ----> the time in hours spent playing pool in a week
y ----> the time in hours spent for ice skating in a week
we know that
----> inequality A
-----> inequality B
using a graphing tool
The solution is the shaded area
see the attached figure
Remember that the time can not be a negative number
If a ordered pair is a solution of the system of inequalities, then the ordered par must lie on the shaded area of the solution
Looking at the graph
Two possible solutions are
(10,10) ----> this point lie on the shaded area of solution
That means -----> The time in hours spent playing pool in a week is 10 and the time in hours spent for ice skating in a week is 10
(4,8) ----> this point lie on the shaded area of solution
That means -----> The time in hours spent playing pool in a week is 4 and the time in hours spent for ice skating in a week is 8
