Investigate inequalities with this instructional video. A lecturer presents an inequality that will take multiple steps to complete and works through the problem step-by-step, numbering and labeling each action she takes. This video is straightforward and could be used as a reteach or to clarify, for any learner, how to solve inequalities .
Don't skip this word problem! Take one piece at a time in writing out this inequality. Once you have an expression that represents the words in this inequality, the rest will seem easy. So watch this video to get a better understanding of how to solve this inequality. And don't forget about flipping the inequality sign because there are operations done with negative numbers.
Instruct your pupils on solving inequalities by multiplying by positive numbers with this video. The video presents how to do just this in step-by-step fashion. A straightforward video, this could be used to supplement your lesson during class, or you could give this to learners to view if they need a review while they work on homework or other assignments.
After reading this inequality word problem, young learners might just skip over it and not even make the attempt to solve it. It seems rather complicated. So watch this video as the teacher explains all that needs to be done to solve this word problem. There are some given values in this compound inequality, and only one variable. This is doable. Learn how to set up the equations need to solve this compound inequality.
Applying the multiplication property of inequality is just like working with linear equations. What is done on one side of the equation needs to be done on the other side of the equation. So this rule can be applied to inequalities. In this example, perform multiplication on each side of the inequality.
Provide this video as additional instruction on how to solve inequalities when you need to multiply positive fractions. The focus of this video is on how to use the multiplication property of inequalities correctly. The lecturer explains each step as she goes through an example problem. Definitely a decent resource.
Is the boundary line part of the graph of an inequality? Here's a hint: the sign of the inequality holds the answer! Are the brain cells firing up trying to figure out what that means? Watch this video as the instructor graphs the inequality and shows how to check if the boundary is part of the graph of an inequality, and how to determine if it is not.
This real-world word problem seems pretty complicated, but it's really not. It only takes four steps once you have an original expression to solve this problem. There are some negative numbers involved in this inequality. So don't forget that if one of the steps entails multiplying or dividing by a negative number, the sign of the inequality MUST be flipped! Watch this video for a clearer understanding.
This video shows a quick definition and some examples of how to apply the division property of inequality. It's just like working with linear equations in that what you do on one side of the equation needs to be done on the other side of the equation. So this rule can be applied to inequalities. In this example, perform division on each side of the inequality.
In a system of linear equations, the solution must satisfy each of the equations to be true. Thus, in a system of linear inequalities, the solution must satisfy each of the inequalities to be true. This is a short video that defines what makes a system of inequalities.
The addition property of inequality is just like the addition property of equality. They each state that whatever is added to one side of the equation or inequality must be added to the other side. Watch this video and see how the instruction shows you what this means in an inequality expression.
A word problem that needs to be written as an inequality to solve. This expression seems pretty straightforward and only takes one step to solve. But wait, the division property was used with a negative number so the inequality sign has to be flipped. Check out this video to see how that happens.
It just doesn't seem right to lose points when answer a question incorrectly. Well, that's what this word problem is all about. So calculate how many incorrect answers the team gave. Don't forget to flip the inequality when dealing with negative numbers. Watch this video for some reinforcements.
Ingrid got some good advice from her father about building a bridge out of pasta. Now she has to do some calculations to build a strong pasta bridge. Figure out how tall she can build her bridge based on a given length. Two given values and one variable. See how to set up and solve this inequality by watching this video.
Examine the multiplication property of inequality with this video. An instructor goes through a problem, detailing how to solve an inequality when you need to multiply negative fractions. She defines reciprocal and puts the final response in set notation. Reach your struggling learners with this video and provide this for them when they are working in class or at home.
A word problem with one variable and two given numbers. This word problem seems doable from the start. Wait, it's an inequality. Don't worry about that piece, just get the expression written and do the math. Watch this video and see how to solve t his inequality in one step.
You've got a linear system of inequalities? You need to solve it by graphing? No sweat. Make sure that each equation is in slope-intercept form and then graph each equation. Is it a solid line or a dashed line? Which side of the line gets shaded? Where do the planes overlap? You can get the answers to all these questions and more by watching this video.
You might be familiar with graphing a quadratic equation but what about a quadratic inequality? This video walks you through an example of graphing a quadratic inequality by first graphing a quadratic equation using factoring to find the zeros, and then looking at how the inequality influences the answer.
Most of the rules that are used to solve equations can be used to solve inequalities. Take a look at the subtraction property of inequality. What is performed on one side of the inequality must be performed on the other side of the inequality. So, if a subtraction is going to be done, do it on both sides. Watch this video for a clear explanation.
Do you know how to graph a linear equation? If you do then graphing an inequality will not be a problem for you. There are a couple of differences: is the line solid or dashed, and which half plane do you have to shade. Watch this video and see that it is not as difficult as you might have thought.
