Question 131924: Please help!
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 with an inequality sign, is there ever a time when the same value will be
a solution to both the equation and the inequality? Write an inequality and provide a value that
may or may not be a solution to the inequality.
Please and Thank You=)
