A system of linear equations is said to be homogeneous if the constants on the right-hand side are all zero. The system 2x1 − x2 + x3 + x4 = 0 5x1 + 2x2 − x3 − x4 = 0 −x1 + 3x2 + 2x3 + x4 = 0 is an example of a homogeneous system. Homogeneous systems always have at least one solution, namely the tuple consisting of all zeros: (0, 0, . . . , 0). This solution...

Determine whether the following statements are true or false and provide a justification for your response. If the coefficient matrix of a system of linear equations has a pivot in the rightmost column, then the system is inconsistent. If a system of equations has two equations and four unknowns, then it must be consistent. If a system of equations having four equations and three unknowns is consistent, then the solution is unique. Suppose that a linear system has four equations...

Case No 2 At times when “everybody’s doing ERP”, users say they can still gain a competitive advantage from implementing ERP systems. Users of ERP can have competitive advantage from the way they implement the systems and can best make use of resulting data. Also, users say the system can make them more nimble in the marketplace than companies with hard to change custom programs. ERP users can identify the biggest gain is that they force a company to institute...
