At my work place there are certain individuals including myself that are discussion God and all aspects of God. The thing is this one person is a non believer, is angry and mad at God. Now he is open to debating and discussing but at what point does a Christian stop explaining or stop debating or...

How can you solve a pair of equations with 2 variables if you've been given a matrix with the variables? Like suppose you're given (4 -1 ) (-3 2 ) and the two equations given are y = 4x + 8 2y -3x + 1 = 0

I know how to compute determinants its not very difficult but I get confused when there are weird notations thrown in. So I'm not exactly sure on this question computer det(A-λI) for this linear system x_1 + 2x_2 = λx_1 2x_1 + x_2 = λx_2 I know that the characteristic equation is λ^2 -...

using these linear equations: 2x + 5y= 6 3x + 4y= 8 I have to write these in the form AX= B where A, X and B are matrices. how do I do this??
