What is the difference between an equation and an inequality? a - an equation includes numbers, but an inequality doesn't
b- an inequality includes numbers, but an equation doesn't
c- an equation includes an equal sign, but an inequality doesn't
d- an inequality includes an equal sign, but an equation doesn't

C - an equation includes an equal sign, but an inequality doesn't

Step-by-step explanation:

Although both equations and inequalities are ways to show how expressions relate to one another, an equation is the relationship between expressions with an equals sign ( )  between them, however, an inequality is a way to express two or more expressions with , , or between them. They both include numbers, so the correct option is C.

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
