Due on Tuesday · Why does the inequality sign change when both sides are multiplied or divided by a negative number? Does this happen with equations? Why or why not? Write an inequality for your classmates to solve. In your inequality, use both the multiplication and addition properties of inequalities. Consider solving your classmates’ inequalities. Explain how you arrived at your answers. Also, help other students who may be having difficulty solving inequalities. Ask clarifying questions if you need additional assistance. 1. The inequality sign changes because when each side is divided or multiplied by a negative number, you are switching the signs of the numbers on each side. To make

Unformatted text preview: the inequality still valid, it is said to flip the sign. If it is: If it is >, it will become < If it is <, it will become > If it is <=, it will become => If it is =>, it will become <= If you do not flip the sign, then the answers are a whole different range which are not valid and will not work in the inequality anymore. In an equation, this does not apply since each side is equally balanced so doing something on one side will be done on the other side, so nothing will be changed. Any ways, there is no way to actually "flip" an equal sign. Inequality to solve:-2(2x+3x-2) > -7(x-x+7x-10) + 2x/x HINT: The answer is a nasty fraction...

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
