Question

Solve the inequality and graph the solution.
5≤
f/4
+7
To draw a ray, plot an endpoint and select an arrow. Select an endpoint to change it from closed to open. Select the middle of the ray to delete it.

Answer 1

Start with
5 ≤ f/4 + 7

Subtract 7 from both sides:
5 − 7 ≤ f/4 → −2 ≤ f/4

Multiply both sides by 4:
−8 ≤ f

So f ≥ −8. In interval notation: [−8, ∞).

Graph: closed dot at −8 with a ray extending to the right (arrow pointing to +∞).
