Questions and Answers

What is the correct interpretation of the given matrix in the context of the system of equations?

  • It shows that there are no solutions for the system of equations.
  • It represents the coefficients for the equation $-3x - y + 5z = -8$. (correct)
  • It is an identity matrix with no relation to the equation.
  • It indicates a complete systems of equations with unique solutions.
  • Which of the following represents the correct values to fill the 3x3 matrix for the equation $-3x - y + 5z = -8$?

  • [ -3 -1 5 ] (correct)
  • [ -8 0 0 ]
  • [ 0 0 0 ]
  • [ 1 0 0 ]
  • What operation would you perform to calculate a solution for $z$ given the equation $-3x - y + 5z = -8$?

  • Multiply both sides by -5.
  • Divide by 5.
  • Add 3x and y to both sides. (correct)
  • Subtract -8 from both sides.

    Systems of Linear Equations

    • A system of linear equations is a set of two or more linear equations that can be solved simultaneously.
    • The given system is represented in matrix form.
    • The matrix displays the coefficients of the variables (x, y, z) and the constants in the equations.
    • Empty cells in the matrix represent the missing coefficients.
    • The task is to fill the missing cells in the matrix so they match the given system of equations.
    • In the matrix provided, -3x - y + 5z = -8 is the associated system of equations.
