Q:Week 3 DQ 1
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.
Week 3 DQ 2
How do you know if a value is a solution for an inequality?
How is this different from determining if a value is a solution to an equation?
If you replace the equal sign of an equation and put an inequality sign in its place, is there ever a time when the same value will be a solution to both the equation and inequality?
Write an inequality and provide a value that may or may not be a solution to the inequality.
Consider responding to a classmate by determining whether or not the solution provided is a solution to the inequality. If the value he or she provides is a solution, provide a value that is not a solution. If the value is not a solution, provide a value that is a solution.
