Question 765679: how do you solve this type of problem?
Solve the inequality, write your solution in interval notation, and graph the solution set on a number line: 12-3x >33 (the greater sign should have a horizontal line under it.

write your solution in interval notation, and graph the solution set on a number line: 12-3x >33 (the greater sign should have a horizontal line under it-------
Add 3x t both sides to get:
12 >= 3x+33
---
Subtract 33 from both sides:
3x <= -21
----
x <= -3
=================
Draw a number line.
plot x = -3,-2,-1,0,1, etc
----
Draw an enclosed (solid) circle at x = -3
Draw an arrow from that point to the right.
---
The point and the arrow are the graph you want.
