In this tutorial, I will explain how you can solve an inequality to identify the possible x values that make this inequality true. I will then describe what the actual answer means to us.
In this tutorial, we will discover how to find the equation of a line using the Point-Slope formula.
In this problem, we will determine the slope and y-intercept of line AB. We will put those two values in slope-intercept form: y=mx+b
It is often difficult to grasp the idea of slope when it is first introduced. A simple way to think about it is the “steepness” of the line on the graph. The most common equation to find slope is y=mx+b. In this equation, m represents the slope.
The distributive property is used in algebra to simplify a term. One part of the term will be the coefficient (the number on the outside), and the other will be the brackets (the numbers within the brackets). Any of these numbers could be a variable (an unknown number). For example: 6(x+2) When there is no…
Pythagorean Theorem is over complicated in most class rooms and I want to simplify it. Originally Pythagoras, the guy who is credited with this theorem, was not doing “math” at all. He needed to find distance’s between two points and he stumbled across this proof. Pythagoras found that if he went 3 steps to the…
Simplicity is often something not attributed to math, but squaring numbers should be. Do you know why we say “the square of x is…”? It’s very simple, we are really saying “the area of a square with sides x is…”. Remember that any rectangle has an area of its length times its height (area=(length)*(height)). And…
When evaluating an expression, the operations inside parentheses must be performed first. So is the same as . Both are equal to 1. The correct treatment of plus and minus signs often causes confusion, especially when there are variables in the expression.
In general, a one-variable equation such as ax+b=c can be solved by “undoing” the order of operations (PEMDAS). The order of operations is: parenthesis, exponents, multiplication, division, addition, subtraction. By doing the order of operations in reverse, we unravel the equation and isolate the variable.
