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.
History is anon-example of math.
Linear algebraic inequalities can be described as an expression with a variable >/< an expression with a variable. For example, 2x<90 so x<45. Inequalities don't yield a particular solution, but rather solution sets. In the above example, x<45, means that the solution set is all of the values less than 45.
