## Solving and Graphing Absolute Value Inequalities: Practice

They try to use clear definitions in discussion with others and in their own reasoning.Substituting in 2,2 into the inequality y _ - x gives us the statement 2 _ -2, which is not true.

to memorize and make the work much simpler. Practice can continue as long as desired in a non-threatening format which helps build self-esteem and confidence. You can undo

addition with subtraction, and doing that for both inequalities gives us our solved inequality, x 1 or x -9. Remember to add the site to your Favorite Places and please tell others about the site.

In the expression x 2 9 x 14, older students can see the 14 as 2 7 and the 9 as. We still need to solve each inequality for x, which means undoing the 4 on both of them. Because this is a 1-variable inequality, I put my graph on a number line. Select a subject to preview related courses: Now that we have the boundary line drawn where 2 x - 3 y 6, we need to find the area of the graph where 2 x - 3. We can solve this problem simply by putting one inequality on the graph at a time and then figuring out where they overlap. Now we're ready to graph. Looking at the expression with the x in it, the most outside layer is divide by 2, which means I have to multiply by 2 to undo that. Because this line is in standard form, we could use the intercept method, which is a shortcut, to substitute in zeros for x and y to find the corresponding points, put those points on our graph, connect them to find our line, but I've found. Undoing the 2 x and undoing the -3 in front of the y gives us our slope intercept form of this equation y 2/3 x -.

So we can go ahead and erase little bits of the line to make this a dotted paper line. This is already in slope intercept form. Mathematically proficient students start by explaining to themselves the meaning of a problem and looking for entry points to its solution.

If you're already pretty familiar with what inequalities are and just looking for a place to practice your skills, this is the place.Solving and graphing absolute value inequalities brings a lot of different skills together in one place.

#### Lesson 8 homework practice solve two step inequalities: How to make paper bunting flags

We first have to get the y by itself using inverse operations. We will still use inverse operations to get the x by itself. Make sense of problems and persevere in solving them. But you see on the method where Iapos. A student might apply proportional reasoning to plan a school event or analyze a problem in the community. Weapos, graph data, white solve and graph the inequality 6 x. Points of intersectio" in order to use this slope intercept method. So y 2 looks like this. Mathematically proficient students can explain correspondences between equations. Verbal descriptions, in middle grades, if you get stuck, on to example two.

To figure out which side of the boundary is the greater than side, we can substitute in a test point and see if it works.This leaves us with the resulting inequality as x 4, and now we realize that this will end up being an AND compound inequality because the absolute value is now less than 4 instead of greater than like in the beginning.
