A linear equation will typically take the form of x = 5y or perhaps x = 2 + 5y. These expressions can be used to explain any number of different things, so they can be studied in the context of real world events. An example might be the number of times that I log into a website, and how that can be predicted in a linear fashion based on certain antecedent events. We'll take Facebook as an example. The first thing that needs to happen for me to log into my Facebook account is that I need to access the Internet. I have a computer and I have a phone, and those two devices are my primary means of accessing the Internet. For the sake of simplicity, using a computer on campus will be treated as using my computer at home. Here is how the linear equation works. Every time I log onto my computer, I access Facebook an average of 1.8 times. I almost always access it once, but not always twice. That depends on how long I was on the computer for, and how many other things I have to do before I sign off. The number of times I go online with my phone it higher, but I use Facebook on my phone less, usually if I have received an alert about something. So the number of times I access Facebook per login on my phone is 0.23 times on average. This gives us a linear equation as follows: F = .23P + 1.8C, where F = number of times I log into Facebook, as a function of P = number of times I use my phone and C = number of times I use my computer. On a day where I am busy with school and work I

This is the result of solving an equation to find a value(s) for the variable(s) which make the equation true.
This paper comprises an appreciation of data representation, its visualization, an outline description of behavior, plus an indication of the use of the equation in engineering.
Linear regression is an approach for modeling the relationship between a scalar dependent variable Y and explanatory variables (or independent variables) denoted X. Function $f(X,W)=Y$ (shown below) can be learned to predict future values.
This unit is based upon the understanding of linear equations in algebra, a unit that is very rigorous. In this unit a student will learn how to create, solve and graph linear functions. Word problems will be used as a tool for students to learn how to create equations between quantities. While exploring this unit, students will also
I would enjoy taking pre-AP Algebra II because I want to be ready for college courses. I love challenging myself, especially in math because that is my favorite subject. I will be willing to put as much time doing things for this class, like studying and doing homework. This year, because of geometry, I have figured out how hard classes can be, but also how much help all of the homework and study flashcards have given me. Also, I can easily complete assignments on my own because I have plenty of time to work on them and I enjoy working by myself. Taking pre-AP Algebra II would help significantly in the future.
6.EE.B.6 Use variables to represent numbers and write expressions when solving a real-world or mathematical problem; understand that a variable can represent an unknown number, or, depending on the purpose at hand, any number in a specified set.

The Impact of Cell Phones On the Canadian Life Cell phones have been accepted as a part of the everyday Canadian life. Since the popularity of technology has drastically risen over the recent years, the impact it has also increased. Although there is many benefits to cell phones, I believe the negative impact greatly surpasses the positive impact on our lives today. Society has become so dependent on cell phones it’s almost unbearable to go 24 hours with out it. We are so reliant on texting that our interpersonal skills are suffering.
Problems 1 through 5: Find the roots (values of x when the expression is equal to zero) using factoring. Prove your answers are correct by checking, or showing that the values of x you computed satisfy the original equation.
Adolescent girls were asked how long they spend on the internet each disregarding hours spent for homework. The answers ranged from 0-6 hours. After measuring everything else the researchers asked the girls if they had Myspace
First is the advertising. According to the case, we know that the major revenue of Facebook is advertising, which took up 98 percent in 2009, 95 percent in 2010 and 85 percent in 2011. Facebook uses all information uploaded by users to become the property of the firm. By analyzing database, Facebook provides advertisers target customized services and products based on users’ preferences and connections. In its view, the advertising which based on social
Facebook is estimated to have over 845 million users, mostly college-aged young adults. Its explosive growth and reputation in social networking have made it not only a market leader, but also a household brand name. The audience is global (excluding China) and the site has now been translated into 70 different languages.
As of this morning, 500 million people all around the world are actively using Facebook to stay connected with their friends and the people around them (Zuckerberg, 2010).
PART A – Linear Programming 1 a) Linear Programing Model Decision Variables: Let x = acres of watermelon Let y = acres of cantaloupe Objective Function: Maximize Z = 390x + 1300y – 5(20x + 15y) + 5(2x + 2.5y) = 270x + 300y – 100x + 75y + 10x + 12.5y = 256x + 284.5y where Z = total profit 390x = profit from watermelons 1300y = profit from cantaloupe 5(20x + 15y) = cost of fertilizer 5(2x + 2.5y) = cost of labour Identification of Constants: Maximize Z = 256x + 284.5y
