7. Answer: +4, x ≥ 16
<u>Step-by-step explanation:</u>
x - 4 ≥ 12
Add 4 to both sides (to isolate the variable):
x - 4 <u>+ 4</u> ≥ 12 <u>+ 4</u>
x ≥ 16
Graph has a closed dot with an arrow pointing to the right of 16.
16 ·------------→
9. Answer: x ≤ 9
<u>Step-by-step explanation:</u>
x - 20 ≤ -11
Add 20 to both sides of the equation:
x -20 +20 ≤ -11 +20
x ≤ 9
Graph has a closed dot with an arrow pointing to the left of 9.
