SVEN [57.7K]

Answer:

Is not a possible solution

Because the number of hours can not be negative

Step-by-step explanation:

x------> the number of hours in the dog walking job

y----->  the number of hours in the sales job

we know that

x+y\leq 60 -----> inequality A

7x+12y\geq 450 ------> inequality B

Remember that

If a ordered pair is a solution of the system of inequalities

then

the ordered pair must satisfy both inequalities

we have

(-3,50) ------> Is not a possible solution

Because the number of hours can not be negative
