Algebra‚ we have to go back over 3700 years‚ to the Babylonian civilization. Babylonians were particularly proficient algebraists and in the ancient civilizations they could solve quadratic problems (Kleiner‚ 2007). Records show that in 1600 B.C equations and symbols were not used in these problems‚ rather they were written out and solved verbally (Corry‚ 2005). Corry’s (2005) study found that a typical example of a problem made by the Babylonians was‚ Method of calculating a quantity‚ multiplied

reactions are equal‚ causing the reactants and products to be created at the same rate. This can be expressed mathematically in the form of the equilibrium constant. The following is the general equation for a reversible chemical reaction: aA+bB →cC+dD Equation 1 Equation 2 below will give the equilibrium constant‚ Keq‚ for this general reaction‚ where the square brackets refer to the molar concentration of the reactants and products at equilibrium.

of a line and one point on it. In order to solve a problem and write an equation using the point-slope form you need two things. Those things are a point on the line‚ (x‚y)‚ and the slope of the line. For example‚ say the slope of your line is 4 and a point on the line is (1‚5). You would insert the 4 in place of the m‚ the 1 in place of the x1‚ and the 5 in place of the y1. When you plug everything into the point-slope equation you get: y-5=4(x-1). The second form‚ slope-intercept‚ is written as

that are achieved by the gold medalists. Also it shows that it is not constant. Linear Regression To create a certain equation‚ you draw the best fit line on the graph. The difference between the red graph and the linear function is that the red does not have a predictable pattern. When the best fit is drawn it is possible to find the equation of this graph. Though the equation that is made by the best fit and three points on the graph is actually on the line‚ there is a limit. Such as the y axis
