Answer:
A. -12
Step-by-step explanation:
A graph shows the vertices of the feasible region to be (0, 6), (3, 0) and (0, -3). Of these, the one that minimizes f(x, y) is (0, -3). The minimum value is ...
f(0, -3) = 3·0 + 4(-3) = -12
_____
<em>Comment on the graph</em>
Here, three regions overlap to form the region where solutions are feasible. By reversing the inequality in each of the constraints, <em>the feasible region shows up on the graph as a white space</em>, making it easier to identify. The corner of the feasible region that minimizes the objective function is the one at the bottom, at (0, -3).
Answer:
I used a little bit of the question i am on Right Now but the answer is in there somewhere
Step-by-step explanation:
ratio for boys: 3 soccer/5 basketball
ratio for girls: 7 soccer/1 basketball (I think you have a typo when you say "...number of boys who enjoyed basketball
of 7:1" because boys and girls were surveyed separately.)
that said...
90 boys enjoy soccer
3*30/5*30=90 boys enjoy soccer/150 boys enjoy basketball
90+150=240 boys and therefore 240 girls
7/1 is the ratio for girls
7+1=8, 240/8=30
7*30/1*30=210 girls enjoy soccer/30 girls enjoy basketball (210+30=240)
