Answer:
All 4 are solutions to the inequality.
Step-by-step explanation:
What we know:
The inequality requires that 48/f is less than or equal to 46.
Plug in each of the choices to see if that will work
48/12 ≤ 46
4 ≤ 46, so f = 12 will work.
48/-12 ≤ 46
-4 ≤ 46, so f = -12 will also work.
48/-3 ≤ 46
-16 ≤ 46, so f = -3 will work as well.
48/8 ≤ 46
6 ≤ 46, so f = 8 will work as well.
Since all 4 work, that means you should check all 4 choices on the question.
Divide both sides by to get
Substitute , so that . Then
The remaining ODE is separable. Separating the variables gives
Integrate both sides. On the left, split up the integrand into partial fractions.
Then
On the right, we have
Solving for explicitly is unlikely to succeed, so we leave the solution in implicit form,
and finally solve in terms of by replacing :
