2014/9/16 Linear Equations Ad Options Ads by Vidx Linear Equations A linear equation is an equation for a straight line These are all linear equations: y = 2x+1 5x = 6+3y y/2 = 3 x Let us look more closely at one example: Example: y = 2x+1 is a linear equation: The graph of y = 2x+1 is a straight line When x increases‚ y increases twice as fast‚ hence 2x When x is 0‚ y is already 1. Hence +1 is also needed So: y = 2x + 1 Here are some example values: http://www.mathsisfun.com/algebra/linear-equations

Answers are hi-lighted yellow. Company A’s nationally advertised brand is Brand X. Contribution to profit with Brand X is $40 per case. Company A’s re-proportioned formula is sold under a private label Brand Y. Contribution to profit with Brand Y is $30 per case. Company A’s objective is to maximize the total contribution to profit. Three constraints limit the number of cases of Brand X and Brand Y that can be produced. Constraint 1: The available units of nutrient C (n) is 30. Constraint 2:

Linear Functions There are three different ways to write linear functions. They are slope-intercept‚ point-slope‚ and standard form. There are certain situations where it is better to use one way than another to solve a problem. It is important to understand and comprehend the mechanics of these three forms so that you know what form to use when solving a problem. The first form‚ point-slope‚ is written as y-y1=m(x-x1). M is the slope and x1 and y1 correspond to a point on the line. It’s good to

As we saw in the previous chapter‚ there are many ways to evaluate even this simple query‚ each of which is superior in certain situations‚ and the DBMS must consider these alternatives and choose the one with

Plots Linear regression is a crucial tool in identifying and defining key elements influencing data. Essentially‚ the researcher is using past data to predict future direction. Regression allows you to dissect and further investigate how certain variables affect your potential output. Once data has been received this information can be used to help predict future results. Regression is a form of forecasting that determines the value of an element on a particular situation. Linear regression

Linear Programming History of linear programming goes back as far as 1940s. Main motivation for the need of linear programming goes back to the war time when they needed ways to solve many complex planning problems. The simplex method which is used to solve linear programming was developed by George B. Dantzig‚ in 1947. Dantzig‚ was one in who did a lot of work on linear programming‚ he was reconzied by several honours. Dantzig’s discovery was through his personal contribution‚ during WWII when Dantzig

student.They are talking about the new trends of logistics areas.The useful words which may be involved in the dialog are as follows.Please try to design the dialog. J（John） T（Tom） T: Hello Mr.Jonh‚these days I have read some books on the the trends of logistics in the future.But I found that articles about the field is not as enough as I expected. I think the problem has an important significance for the future development of logistics. So I would like to ask your opinion about this
