Dr. Chris Steele guides us through how to find the 5 Cs of a sick child. When you have a child who is running a fever, it's important to remember not to heat up your home and wrap them in a ton of blankets. This is the worst thing you can do because you're increasing the warmth around them, which is going to increase their brain and body temperature. If your child has a fever, remember to cool them. Cool their room, cool a wash cloth to place on them, cool drinks, cool ice cream, and cool bed...

In this video the instructor shows how to solve systems of linear equation by graphing. A system of linear equation is equations of two lines that are to be graphed on the same coordinate axes. Now take the first equation and write it to form y = mx + b. Now extract the value of slope m and graph the line as shown in the video. Similarly graph the equation of the second line as shown in the video. Now if the two lines intersect at a point, that point is the solution to the system of that line...
This tutorial looks at how to describe a linear system without actually graphing it. In order to do that, you will need to convert both equations of a problem into the Y=mx+b format. Once you have done this, you will be analyzing the m and b values. There are a few rules to follow. If the slopes (or m) and the Y intercepts (or b) are equal, there are an infinite number of solutions (or dependent equations). A second rule is if the slopes are equal and the Y intercepts are different, then the ...
This is a very interesting mathematical instructional video on how to find rational equation with no solution. How to solve the equation and check the answer. Let us take the example m over m-3 minus 4 is equal to 3 over m-3. In this equation we get m-4m+12 over m-3 is equal to 3 over m-3. When we simplify it further we get -3m +12 = 3. Or -3m = -9 and m = 3. This video teaches you very clearly how to solve a rational equation with no solution.
Learn how to find latent finger prints on brass surfaces, such as fired cartridge cases. Called the Acidified Peroxide method, using only white distilled vinegar and hydrogen peroxide that you can find at your local drugstore, you can uncover fingerprints that is usually impossible to see using other methods. After mixing the vinegar and hydrogen peroxide the solution should start turning a greenish color around the brass object after 5 to 10 minutes. After you see the green color throw away ...
Elimination in mathematics is used to find the solution set of a system of equalities. This video tutorial shows how to use elimination to find the solution set of a given equation and offers several examples to illustrate the process. Before applying this method, the equation must be in the form “Ax +By=C.” When graphing a set of mathematical equations that intersect, the answer to the elimination is the point on the graph where the two lines cross.
