To show in the example 1x>2y<4000, 1x is smaller than 2y but 2y is bigger than 4000. ok?
2x-5<7 2x<12 x<6 -3x+5>11 -3x>6 x<-2
Compound inequalities are inequalities that have more than one sign, for example, 5

No. For example, the solution to x ≤ 4 and x ≥ 4 is x = 4.
Inequalities originated from math, which originated from different civilizations. So inequalities most likely originated from one of the civilizations that contributed to crating math.

Explain the addition and multiplication properties of inequalities
Two inequalities are equivalent if their solution sets are the same. For example, the inequalities 2x > 6 and 3x > 9 are both equivalent to x > 3.
According to the site Math Planet, 'A compound inequality contains at least two inequalities that are separated by either "and" or "or".' In the case of "and", a compound inequality such as x > -1 and x < 2 can also be written as: -1 < x < 2 (I also took this example from Math Planet.) There is no such shortcut for the "or" case.
Inequalities are embedded in society in all geographical areas, and in a number of different ways. For example there are inequalities in gender, in socioeconomic status, and in society's treatment of people of different races.
No. For example, the solution to x ≤ 4 and x ≥ 4 is x = 4.

Hi, my daughter's math teacher recommended a website to his students. It has a lot of math video lessons on various math topics, including the one you need help with. Please click the below link 'Free absolute value inequalities video'. It is all FREE to use! It was very helpful for my child. Hope it will help you, too. Good luck!
