WebThe 2 inequalities have completely separate graphs. All values from both graphs become the solution: x > -2 or x < -5; or in interval notation: (-infinity, -5) or (-2, infinity) -- graph x > -2 or x > 5. The graphs of the inequalities go in the same direction. We need a set that includes all values for both inequalities. WebGive the solution set in interval notation.

WebIn mathematics, an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions. It is used most often to compare two numbers on the number line by their size. There are several different notations used to represent different kinds of inequalities: The notation a < b means that a is less than b. WebExamples of algebraic notation. As discussed earlier, algebraic notation is used to make express statements more concisely. ... and not equal to, ≠, signs are all symbols that are also used to denote the inequality of quantities. The operators +, -, ×, and ÷ are used to denote the relationship between values such that if you have 2 x + 1 ...
WebThe notation of greater than (>) and lesser. than (< ) is often used in quadratic equations. The quadratic equation ax 2 + bx + c = 0 is written as a quadratic equation by replacing equals to the symbol (=) with greater than or lesser than inequality. The general format of a quadratic inequality is ax 2 + bx + c > 0, or ax 2 + bx + c < 0. Further, let us check some …
