Sketch the graph of the solution set for the following system Of inequalities: $$ \left\\{\begin{array}{l} {y \geq n x+b(n<0, b>0)} \\ {y \leq m x+b(m>0, b>0)} \end{array}\right. $$
Consider the objective function \(z=A x+B y(A>0\) and \(B>0\) ) subject to the following constraints: \(2 x+3 y \leq 9\) \(x-y \leq 2, x \geq 0,\) and \(y \geq 0 .\) Prove that the objective function will have the same maximum value at the vertices \((3,1)\) and \((0,3)\) if \(A=\frac{2}{3} B\).
For the linear function \(f(x)=m x+b, f(-2)=11\) and \(f(3)=-9 .\) Find \(m\) and \(b\).
Explain how to solve a system of equations using the addition method. Use \(3 x+5 y=-2\) and \(2 x+3 y=0\) to illustrate your explanation.
An objective function and a system of linear inequalities representing constraints are given. a. Graph the system of inequalities representing the constraints. b. Find the value of the objective function at each corner of the graphed region. c. Use the values in part (b) to determine the maximum value of the objective function and the values of \(x\) and \(y\) for which the maximum occurs. Objective Function Constraints $$ \begin{aligned} &z=10 x+12 y\\\ &\left\\{\begin{array}{l} {x \geq 0, y \geq 0} \\ {x+y \leq 7} \\ {2 x+y \leq 10} \\ {2 x+3 y \leq 18} \end{array}\right. \end{aligned} $$
