Solve the inequality r + 4 ≥ 16

Question

Graph the solution.

Answer 1

To solve the inequality r + 4 ≥ 16, we need to isolate the variable r.

r + 4 ≥ 16

Subtracting 4 from both sides:

r ≥ 16 - 4

r ≥ 12

So the solution to the inequality is r ≥ 12.

To graph the solution, we draw a number line with a closed circle at 12 and shade everything to the right of 12.
