Answer: x < 1/2 or x < 0.5
The graph is below
=========================================================
There are two ways to solve this
Method 1
5 - 2x > 4
-2x > 4-5
-2x > -1
x < -1/(-2) .... note the inequality sign flips
x < 1/2
x < 0.5
The inequality sign flips whenever we divide both sides by a negative number.
----------------------
Method 2
5 - 2x > 4
5 - 2x+2x > 4+2x
5 > 4+2x
4+2x < 5
2x < 5-4
2x < 1
x < 1/2
x < 0.5
----------------------
To graph this on a number line, we'll plot an open hole at 1/2 or 0.5 on the number line. Then we shade to the left to represent all values smaller than 1/2 = 0.5
The open hole signals that 0.5 itself is NOT part of the solution set.
See the diagram below.

Answer:
Step-by-step explanation:
While some might feel that online learning is the fun leisurely form of schooling that grants tons of free time, it honestly gets old quick. Being in quarantine makes it all the more worse because you do nothing all day. On the subject of math though, it is a disservice to have to learn math online. Personally, it is my experience that having a physical teacher and classroom to learn with is crucial to ones mathematical ability, but it's not the end of the world, it won't last long and it won't affect you that bad. Sure, the benefits include having more control over your day which is a good source of preparation for college life and responsibilities of being an adult, but you lose daily interpersonal interactions and typical casual daily exercise, since you no longer walk to class. Nevertheless, we will push on.
