Answer
$a.\quad $True
$b.\quad $True
$c.\quad $False
$d.\quad $True
$e.\quad $True
Work Step by Step
We compare the statements with (a) to (l) statements of Theorem 8 and rewrite each.
When we write If (x) is true... we mean: If statement (x) in Th.8 is true ...
$a.\quad $
If (d) is true then (b) is true ...
TRUE
$b.\quad $
If (h) is true then (e) is true ...
TRUE
$c.\quad $
This (statement g) is true only for invertible matrices, not for any matrix.
FALSE
$d.\quad $
If (d) is not true then (c) is not true ...
TRUE
$e.\quad $
If (l) is not true then (a) is not true ...
TRUE
