After completing this tutorial, you will be able to complete the following: Write a system of linear inequalities in two variables that corresponds to a given graph. Everything You'll Have Covered Recall that a linear inequality is an inequality involving linear functions. A linear inequality on the plane can have one of the following forms:

Students of all levels continually struggle with word problems; however, there is a solution to this "problem". The objective for this curriculum unit is to show students the multiple ways that system of equations can be used to solve real-world problems. In order for students to be engaged and interested in learning, they need to see the real-world practicality behind the math concept being learned.

Without a lot of practice, System of Equations can be difficult for students to compute correctly and efficiently. When difficulty is combined with a lack of interest or a question of relevance, the student can become frustrated and disengaged.

Therefore, in order to capture the attention and interest of my students, I will first discuss what a system of equations is and then explain how to solve one using three different methods.

This will undoubtedly be of interest to any student. Then I will combine the distance and interest formulas together with a system of equations and demonstrate how to solve real-world scenarios and exciting problems.

I will also provide practical examples of problems involving wind and water currents, chemistry problems involving mixtures and solutions, more interest problems involving the time value of money, and other practical examples that involve systems of equations.

I will spend two days on each of the three methods. Next, I will spend another three or four days introducing the interest and distance formulas, incorporating them into system of equations.

It is critical that the students get a feel for solving the problems before I introduce the more complicated word problems. The distance formulas and simple interest formulas are not extremely complicated, and my students typically pick up on them quickly. I have also introduced them earlier in the year and use them as warm-up problems several times per week.

The first system of equations I will introduce is one that will require the substitution method to solve. Together they have songs. How many songs does each person have? Therefore, if we subtract the first equation from the second equation we will be able to isolate the y variable.

How many lawns did they each cut? An example of a word problem that we could use the multiplication elimination method to solve is: In this particular class, I have relatively few behavior problems. Talking at inappropriate times is my students' biggest fault.

Carmel Middle School is on a block schedule and my Algebra class meets every day for approximately 85 minutes. I have a pacing guide, created by the county I teach in, that I follow. There is not an abundance of time allocated for systems of equations, so I tend to move rather quickly.

I typically have about 30 students in an Algebra class and I have approximately 20 to 25 students in my lower level classes. The population at my school is as follows: Twenty six percent of our students are enrolled in the Gifted and Talented program, while These percentages put us above the Charlotte Mecklenburg District average in both categories.

Write an exponential function y = abx whose graph equations in a and b. 6= ab1 Substitute 6 for y and 1 for x. 24= ab3 Substitute 24 for y and 3 for x. To solve the system, solve for a in the first equation to get a = 6 b Write a power function of the form y = axb whose graph passes through the given points. (3, 27), (9, ) (1.

The District itself is growing larger and larger every year; it currently enrollsstudents and employs 10, teachers. Over the last couple of years, the Charlotte-Mecklenburg School System has increased the number of students by approximately 6, students per year.

Strategies First, I will start with introducing the three ways to solve a system of equations. The first way is called the substitution method. I spend two days on substitution with my class.

Typically, the problems are set up such that there is only one variable on each side of the equation and at least one variable has a leading coefficient equal to one. The other equation has two variables, as well, each on the same side of the equation. An example is as follows: Equations in the above form are the simplest and easiest way to start a substitution problem.

The students need to understand that when there is more than one unknown in an equation, it cannot be solved as is.

I ask for a volunteer to tell me if we now have more than one unknown variable.Create a system of equation that has no solution: write the equations in two different forms(4) Create a system of equation that has infinitely many solution - write the equations in two different forms (4) One important Question: How am I suppose to.

A "system" of equations is a set or collection of equations that you deal with all together at once. Linear equations (ones that graph as straight lines) are simpler than non-linear equations, and the simplest linear system is one with two equations and two variables.
