You make $5 an hour in tips working at a video store and $7 an hour working at a landscaping company. you must work at least four hours per week at the video store, and the total number of hours you work at both jobs and weak cannot be greater than 15. right a system of linear any qualities to model the number of hours that you could work at each location in a week .

 The system of linear inequalities to model the number of hours that you could work at each location in a week are,

Subject : 5x+7y,

and , where x represents number of hours  in tips working at a video store and y represents number of hours  working at a landscaping company.

Step-by-step explanation:

Let x represents number of hours  in tips working at a video store and y represents number of hours  working at a landscaping company.

Therefore total cost which have to be maximized,

Z= 5x+7y,

Now, we must work at least four hours per week at the video store,

Therefore,

And, the total number of hours you work at both jobs and weak cannot be greater than 15.

Therefore,  

Thus, the required system of equation is, Z= 5x+7y, , ,

Since, at ( 4,11) Z= 97 which is maximum value.

Thus the solution of the above system of equation is x=4 and y=11.

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
