May I please have the answers to the Graphing and Writing Inequalities practice? It's for the online school Connections Academy! I can't post the graphs so sadly I won't be able to provide that, but if you know what I'm talking about please provide the answers if that's ok!!!! Lesson 9: Graphing and Writing Inequalities CE 2015
Math 7 A Unit 5: Equations and Inequalities ! I'm so confused and I have no idea how to do this, so when you give me the answers, please provide explanations! Or you could give me the answer and I could try to find out how you got it and respond to you! That way I'll be learning still.
I can't give you my answers, ;; because I don't understand enough to, so can you please explain?
I'm sorry, but I cannot provide the answers to specific practice questions from online schools or specific assignments. However, I can help explain the general concept of graphing and writing inequalities.
To graph an inequality, you first need to understand the symbols used in inequalities:
1. "<" means less than
2. ">" means greater than
3. "<=" means less than or equal to
4. ">=" means greater than or equal to
To graph an inequality, you can follow these steps:
1. Identify the variable in the inequality. For example, if the inequality is "x > 3," the variable is "x."
2. Determine if the inequality is strict (using ">" or "<") or inclusive (using ">=" or "<=").
3. If the inequality is strict, use a dashed line when graphing the inequality. If it is inclusive, use a solid line.
4. Plot the line on a graph, using the variable on the x-axis and the inequality on the y-axis. For example, if the inequality is "x > 3," you would plot a dashed line parallel to the x-axis, passing through the point (3, 0).
5. Determine which side of the line represents the solutions to the inequality. You can choose a test point not on the line, plug it into the inequality, and see if it's true or false. If it's true, shade the region containing that test point. If it's false, shade the other region.
Writing inequalities typically involves translating verbal descriptions into mathematical expressions. Here are some common phrases and their corresponding inequality symbols:
1. "Less than" is represented by "<"
2. "Greater than" is represented by ">"
3. "Less than or equal to" is represented by "<="
4. "Greater than or equal to" is represented by ">="
For example, if a problem states "x is at least 10," you can write it as "x >= 10."
Remember to follow the specific instructions from your lessons and consult with your teacher if you have any specific questions or need further clarification on the concepts. It's important to actively engage in the learning process to truly understand and retain the material.
