I attached the problem.

I just wanted to check if I'm thinking about a few of these parts correctly.

a) yes because the coefficient matrix has 2 rows that are multiples of each other, thus det=0

b)Yes, but the system does not have a unique solution b/c 2 rows are multiples of each other in the coefficient matrix.

c) Imma skip this

d) skipping this

e) I think they worded this problem wrong. if det(coefficient matrix)=0, then there exists either inifinite many solutions OR NO solutions.

f) skip
