Answer:
The answer in the procedure
Explanation:
Let
x ----> the dog walking hours
y ----> the car washing hours
we know that
The system of linear inequalities is equal to
-----> inequality A
-----> inequality B
Solve the system of inequalities by graphing
The solution is the shaded area
see the attached figure
Two possible combinations of hours are
(10,10) and (0,9)
Verify
For (10,10)
Substitute the value of x and the value of y in both inequalities
Inequality A
-----> is true
Inequality B
----> is true
therefore
(10,10) is a possible solution
For (0.9)
Substitute the value of x and the value of y in both inequalities
Inequality A
-----> is true
Inequality B
----> is true
therefore
(0,9) is a possible solution
