thanks your help has been greatly appreciated

haha thanks

For which value of does the matrix -4 k -3 -7 have one real eigenvalue of multiplicity 2?? I use det(µI-A)=0 and end up with µ^2 - 3µ - 28 + 3k but i don't know where to go from here pls help

well this is what i kinda know Ax=0 if you solve for x then x=0, which will make A invertible So, what does that say about Ax=B

If A is an n x n matrix and Ax = 0 has many solutions, then which ones are true?? A. Ax = b has either no solutions or many solutions B. Ax = b has a unique solution for some b C. Ax = b has many solutions for any b D. Ax = b has no solutions for some b or are all of the...
