Question

Help me please!!!!!!!!!!!

Answer 1

Solution: $x \ge 11$

Graph: Closed circle at 11, shading to the right

======================================================

Work Shown:

$x+7 \ge 18\\\\x+7-7 \ge 18-7\\\\x \ge 11$

In the second step, I subtracted 7 from both sides to undo the "plus 7".

To graph this, we place a closed or filled in circle at 11. Then we shade to the right. The endpoint x = 11 is included as part of the solution set, which is why we use a closed circle instead of an open hole.

This visually describes all values that are equal to 11 or larger than 11.
