Inequality (mathematics) - Wikipedia
https://en.wikipedia.org/wiki/Inequality_(mathematics)
WEBNotation. There are several different notations used to represent different kinds of inequalities: The notation a < b means that a is less than b. The notation a > b means that a is greater than b. In either case, a is not equal to b. These relations are known as strict inequalities, meaning that a is strictly less than or strictly greater than ...

WEBWhat are the 4 formats for solutions to inequalities? Solutions to one-variable linear inequalities can be formatted in any of four ways. Using the inequality x < −3 for our examples, these formats are: Inequality notation: x < −3. Set notation: {x | x < −3} Interval notation: (−∞, −3) Graphing: shading (thickening) a number line.

WEB11 years ago. Colby, The equation y>5 is a linear inequality equation. Let's first talk about the linear equation, y=5. If you wrote the linear equation in the form of y=Ax+B, the equation would be. y=0x + 5. When x=1, what is y? y=5. And when x = 2, what is y? y=5. So no matter what x is, y=5.
