Answer:
2) is not proportional, 3) is not proportional, 5) is proportional, 6) is not proportional. 
Step-by-step explanation:
Number 2 is not proportional since it doesn't go through the origin on the graph and the line is not a straight line. 
Number 3 does not go through the origin, so number 3 is also not proportional. 
Number 5 is proportional since when you divide y by x, it is always 7. 
Number 6 is not proportional because when you divide y by x or x by y there are not the same answers.

Answer:
- 3.75 bags of ChowChow
- 0.75 bags of Kibble
Step-by-step explanation:
The constraints on protein, minerals, and vitamins give rise to the inequalities ...
   40c +30k ≥ 150 . . . . . . required protein
   20c +20k ≥ 90 . . . . . . required minerals
   10c +30k ≥ 60 . . . . . . . required vitamins
And we want to minimize 10c +12k.
The graph shows the vertices of the feasible region in (c, k) coordinates. The one that minimizes cost is (c, k) = (3.75, 0.75).
To minimize cost, the daily feed should be ...
- 3.75 bags of ChowChow
- 0.75 bags of Kibble
Daily cost will be $46.50.
