Which matrix represents the system of equations below?


a. -10,-9,13



d. 10,8,5

  • Algebra 2 -

    Ans: a.

    the matrix will have the same signs of the coefficients of the equations.

  • Algebra 2 -

    Actually none of them do
    the constants were completely ignored in all the choices.

    You would want what is called the "augmented" matrix

    -10 -9 13 12
    8 -7 -5 15
    5 4 -6 -12

    btw, the elements of a matrix are not separated by commas
