Question

Express the inequality n > -19/5 using interval notation.

a) [n, [infinity])
b) (-[infinity], n)
c) (-[infinity], -19/5)
d) (-19/5, [infinity])

Answer 1

To express the inequality n > -19/5 using interval notation, the correct answer is d) (-19/5, [infinity]).

Step-by-step explanation:

To express the inequality n > -19/5 using interval notation, we need to determine the range of values that n can take.

Since the inequality sign is greater than, we use an open interval.

Since n can be any value greater than -19/5, the interval notation is (-19/5, ∞).

Therefore, the correct answer is d) (-19/5, [infinity]).
