Harkeerit&Kyra
An absolute value of a number is its distance from zero on the number line. To write an absolute value, use bars (e.g. |5| = 5). To solve an absolute value equation, separate it into two cases - one where the expression inside the bars is positive and one where it is negative. Then solve each case separately and check the solutions. Basic graphs of absolute value functions form a V-shape, with restrictions so the y-values are always greater than or equal to 0. Shifting or stretching transformations can be applied.
Quadratic equations, quadratic inequalities and rational algebraic day 2 5
This document contains a lesson on quadratic equations taught by Rosa Vilma D. Garcia.

Pythagorean theorem and distance formula jo'qwans finished powerpoint
The document discusses the Pythagorean theorem and distance formula. The Pythagorean theorem states that the square of the hypotenuse of a right triangle equals the sum of the squares of the other two sides. The distance formula calculates the distance between two points by taking the difference of the x-coordinates squared plus the difference of the y-coordinates squared. An example applies the distance formula to find the distance between points (8,1) and (9,5).
