When solving numerical problems, it is essential to first understand the problem by carefully reading and identifying the given information and what needs to be found. Next, select and apply the appropriate mathematical operations or formulas to solve the problem systematically. Finally, ensure to check your work by reviewing the solution and verifying that it makes sense in the context of the problem.
When solving word problems involving a system of linear inequalities, you first need to define the variables representing the unknown quantities. Then, translate the given information into a system of linear inequalities. Next, graph the inequalities on a coordinate plane to determine the feasible region. Finally, analyze the feasible region to find the values that satisfy all inequalities, providing the solution to the word problem.
When you multiply both sides by a negative number the inequality must be flipped over. You do not do that when multiplying by a positive number.
Dynamic programming (DP) has been used to solve a wide range of optimizationproblemsWhen solving a problem using linear programming, specific inequalities involving the inputs are found and then an attempt is made to maximize (or minimize) some linear function of the inputs.
