6th Grade Math-Graphing Inequalities on a Number Line (the basics)
Updated version of graphing inequalities https://www.youtube.com/edit?o=U&video_id=HDq7l7CnN-A In this video, you will learn how to basics for graphing ...
Answer
To solve Inequalities we need to understand well the meaning of symbols like these:
Symbol |
Words |
Example |
> |
greater than |
x + 3 > 2 |
< |
less than |
7x < 28 |
≥ |
greater than or equal to |
5 ≥ x − 1 |
≤ |
less than or equal to |
2y + 1 ≤ 7 |
In the example that we have: The ground will be represented as (x) and x = 0
The basement floor (y) is -15 feet: y=-15 where x > y and x = y + 15
The roof (z) is above the ground 25 feet: z=25 where x < z and x = z - 25
