we will draw the graph according to the given  constraints

NOTE: when we draw the graph from constraints inequalities becomes equalities just to draw the graph

Given constraints are:

4x+3y\leq12

2x+6y\leq 15

x\geq0

y\geq0

Now we draw the graph of given constraints using graphing calculator. Please see the attachment for the graph. Shaded region is the feasible region

Answer:

The vertices of the feasible region are (0,0), (3,0), (1.5,2) and (0,2.5).

Step-by-step explanation:

The constraints of the problem are given by,

4x+3y\leq 12

2x+6y\leq 15

x\geq 0

y\geq 0

Zero Test states that after substituting the point (0,0) in the inequalities,

<em>If the result is true, then the solution region is towards the origin</em>

<em>If the result is false, then the solution region is away from the origin.</em>

So, puttin g(0,) in the constraints gives,

4x+3y\leq 12[/tex implies 0 ≤ 12, which is true.[tex]2x+6y\leq 15 implies 0 ≤ 15, which is true.

x\geq 0 implies 0 ≥ 0, which is true.

y\geq 0 implies 0 ≥ 0, which is true.

Thus, all the inequalities will have solution region towards the origin.

So, the feasible region is given as below.

Hence, the vertices of the feasible region are (0,0), (3,0), (1.5,2) and (0,2.5).

Answer: y=7x

Step-by-step explanation:

The way I did it was, I looked at the chart. The highest it goes is 30 and 210. So for your answer, you have to multiply. 7x30 gives you 210 and there y=7x
