The inequality that represents the different sentence is
.
The inequality that represents the sentences that are alike is
.
The given sentences describe inequalities related to the variable k. Let's analyze each statement:
a.
b.
c.
d.
The inequality that represents the different sentence is (d)
. This is because statement (d) is the only one expressing that k is "at least" -3, meaning it can be greater than -3, while the others emphasize that k is less than or equal to -3. In other words, (d) allows for values of k that are greater than -3, making it distinct from the others.
On the other hand, the inequalities that represent the sentences that are alike are (a), (b), and (c), as they all convey that k is less than or equal to -3. These expressions are equivalent and can be used interchangeably.
In summary, the different inequality is
, and the alike inequalities are
, with the latter set comprising statements (a), (b), and (c).
