- Solve the homogeneous linear system corresponding to the coefficient matrix. [121200242412]arrow_forwardOne hundred liters of a 50% solution is obtained by mixing a 60% solution with a 20% solution. Use a system of linear equations to determine how many liters of each solution are required to obtain the desired mixture. Solve the system using matrices.arrow_forwardAugmented Matrix In Exercises 11-18, find the solution set of the system of linear equations represented by the augmented matrix.

- Writing an Augmented Matrix: In Exercises 15-20, write the augmented matrix for the system of linear equations. 2x4y+z=136x7z=223xy+z=9arrow_forwardFill in the blanks. If A is an invertible matrix, then the system of linear equations represented by AX=B has a unique solution given by X=.arrow_forwardMatrix Representation In Exercises 49 and 50, assume that the matrix is the augmented matrix of a system of linear equations, and a determine the number of equations and the number of variables, and b find the values of k such that the system is consistent. Then assume that the matrix is the coefficient matrix of a homogeneous system of linear equations, and repeat parts a and b. A=[21342k426]arrow_forward
- System of Linear Equation In Exercises 31-36, use the determinant of the coefficient matrix to determine whether the system of linear equations has a unique solution.arrow_forwardProof Let A be an mn matrix. a Prove that the system of linear equations Ax=b is consistent for all column vectors b if and only if the rank of A is m. b Prove that the homogeneous system of linear equations Ax=0 has only the trivial solution if and only if the columns of A are linearly independent.arrow_forwardSolving a Linear System Using LU-Factorization In Exercises 47 and 48, use an LU-factorization of the coefficient matrix to solve the linear system. 2x+y=1 y-z=2 -2x+y+z=-2arrow_forward
- Matrix Representation In Exercises 49 and 50, assume that the matrix is the augmented matrix of a system of linear equations, and a determine the number of equations and the number of variables, and b find the values of k such that the system is consistent. Then assume that the matrix is the coefficient matrix of a homogeneous system of linear equations, and repeat parts a and b. A=[13k421]arrow_forwardUsing a Graphing Utility: In Exercises 79-84, use the matrix capabilities of a graphing utility to write the augmented matrix corresponding to the system of linear equations in reduced row-echelon form. Then solve the system. 3x+3y+12z=6x+y+4z=22x+5y+20z=10x+2y+8z=4arrow_forward
