Math (matrices)
No one answered my matrix question. Let me rephrase: Let A, B, and 0 be 2x2 matrices. Assuming that A is invertible and 0 is all zeroes, what is the inverse of the matrix [A0] [BA] (that is a 4x4 matrix represented as 4 2x2

Could you please explain how to use a matrix (matrices) to solve a system of linear equations (two variables)? My book doesn't explain it in a way I can understand. Please and thank you.

i need help with my algebra 2 homework, the section is called using matrices to represent data. here is one of the problems: 1/2A+(BA) A=[7 3 1 5] [2 8 0 4] and B= [6 0 11 3] [5 2 8 9] i don't know how to do this problem

Algebra, Solving equations
I'm stuck with this equation: y = (4x1)/(2x+3) We're working on inverses, which I understand, but my mind is blanking on how to solve this for x. Thanks in advance, Amy :) after you interchanged the x and y variables, and

Math: matrices
If A and B are both square n x n matrices, If AB = I, prove BA = I Presumably you have to do this without using the usual properties of the inverse of matrices. But we do need to use that if there exists a matrix B such that A B =
