f-6 < 6 or f - 4 ≥ 11
Write your answer as a compound inequality with integers.
___or___

Answer 1

f < 12 or f ≥ 15

Explanation:

You want to solve for f the inequalities f - 6 < 6 or f - 4 ≥ 11.

The inequalities are solved separately, and the solutions combined using the conjunction in the problem statement.

f -6 < 6

Add 6 to both sides:

f < 12

f -4 ≥ 11

Add 4 to both sides:

f ≥ 15

The solution is f < 12 or f ≥ 15.
