Answer:
draw a number line with a filled-in circle on the number 15. Then, draw an arrow on the line pointing toward the right side of the number line, or the positive numbers.
Explanation:
to simplify x+5≥20, subtract 5 from both sides of the inequality to isolate x to get
x≥15 because x+5-5=x and 20-5 is 15.
to graph this, draw a number line with a filled-in circle on 15 to demonstrate that x can be greater or equal to 15.
