Joseph is working two summer jobs, making $12 per hour babysitting and making $6 per hour walking dogs. In a given week, he can work at most 9 total hours and must earn at least $90. If Joseph worked 2 hours babysitting, determine all possible values for the number of whole hours walking dogs that he must work to meet his requirements. Your answer should be a comma separated list of values. If there are no possible solutions, submit an empty answer.

There is no possible values for the number of whole hours walking dog

Step-by-step explanation:

Let x is the number of hours working as a babysitting (x ≥ 0)

Let y is the number of hours working as a walking dogs person (y ≥0)

We have a system of inequalities:

If Joseph worked 2 hours babysitting:

2+ y ≤ 9 <=> y ≤ 7 (y > 0) and

12x + 6y ≥ 90 <=> y ≥  11

so there is no possible values for the number of whole hours walking dogs:

Hope it will find you well.

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9
