How To: Solve two linear equations by the elimination method

\When both equations in a linear system are in the form Ax + By = C, you can solve the system using elimination. How is this method different from substitution? The idea behind the elimination method is to create a new equation from a combination of the original equations in the system. The new equation is formed by adding or subtracting the originals. When we combine two true equations, the sum or difference must also be true.

How To: Do a flaming ice experiment

In this fascinating "how to" video, you will see how a simple process creates the illusion of ice that is burning. Only a few items are needed to enact this scientific experiment. As the narrator describes, "Calcium carbide reacts with water to form acetylene gas." To illustrate, the video shows a bowl of ice cubes, to which the special ingredient is added. As the ice melts into water, it reacts with the calcium carbide, forming the high flammable acetylene gas, which is often used in welding...

How To: Make your very own paper spinner

Evil Penguin Master demonstrates how to make a paper spinner. First fold a regular sheet of paper in half, defining the lines well.

How To: Determine if a point lies on a line in standard form

In this video, we learn how to determine if a point lies on a line in standard form. In order to do this, you will need to substitute the X and Y value with the ordered pair that is given. The X value is the first number and the Y value is the second number. Re-write your equation, substituting in the numbers to the appropriate spots. Now, simplify the equation by doing multiplication with the negatives and positives (if given). When you get through the equation, you will end up with the solu...

How To: Write and graph an equation in slope intercept form

This video teaches us the method to write an equation in slope intercept form and to graph it. The equation of line is y = mx + c. m is the slope and c is the y intercept or the point where it crosses the y axis. Let us find the equation of line if it crosses (8,6) and m=1/2. Substituting the values of x,y and m we get 6=(8)(1/2)+b. Simplifying we get b=2. Substituting the values in the equation of line, we get y = m/2 + 2. Suppose we want to find the x coordinate of a point on the line given...

How To: Do a sodium and water experiment
