Writing and using a system of inequalities can involve

The stocks were not worth the same amount in the beginning, so if each stock loses half its value, the new values will not be equal either.

Identify the intersection of the two inequalities and answer the questions that pertain to the problem. Write words to describe the inequality, then math symbols to represent the speed. How many hot dogs were sold and how many sodas were sold?

This is written formally as: Ask yourself, "What am I trying to solve for?

Write, Solve and Graph an Inequality

They stop by a partner and share their inequality. Systems of Inequalities Word Problems As you get further into Algebra 1, you will find that the real world problems become more complex. How many solutions does it represent?

Why is the inequality symbol reversed when the inverse operation involves multiplying or dividing by a negative number? Have them write a new inequality for each guess.

Systems of linear inequalities

Have each student write the words and the inequality for a real-world situation. Those on the right by a negative number 2x. Sarah knows that she will see more than 50 bracelets.

Find one piece of information in the problem that you can use to write an inequality. They have more questions to be answered and require more steps to find the solution. Have students look at the vocabulary and tell a partner something they know about one of the vocabulary words.

Think about what this solution means. Define your variables Use one of the methods for solving systems of equations to solve. How can you show this on the graph?

You have learned many different strategies for solving systems of equations! Gradually increase the complexity of the problem so the student must first write and solve a one- or two-step inequality for a given context.

Be sure the student understands the conventions in graphing inequalities and their meaning e. The team continues to ask all the questions for their bid. Okaloosa Is this Resource freely Available? The exercise below will let us find out. For most real world problems, it will be easiest to graph the inequalities using the x and y intercepts.

Always write your answer in complete sentences!74 CHAPTER 2 Equations, Inequalities, and Problem Solving As we explore in this section, an expression such as is not as simple as possible,because—even without replacing x by a value—we can perform the indicated addition.

Dec 02,  · This video is about Writing and Graphing Inequalities. Using the inequality in this task, demonstrate how this idea can be used in the process of solving. Suggest using two steps to multiply both sides of C by (e.g., by first multiplying both sides of the inequality by five, then dividing each side of the inequality by nine).

B) Have students write each of the following inequalities one at a time as you give them. Have them guess a reasonable solution and write their guess. Then ask them to replace the inequality symbol with an equal sign and solve the equation using inverse operations.

Steps for Solving a System of Inequalities Word Problem. Read the problem and highlight important information.

Writing and Solving Inequalities

Identify the variables. Find one piece of information in the problem that you can use to. The graph shows an arrow beginning on 5 with an open circle and pointing to the left, thus that portion of the graph says, all real numbers less than 5. There is a second arrow beginning on 9 with a closed circle and pointing to the right, representing all real numbers greater than or equal to 9.
