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
