Why might a personal budget include information on both spending and saving habits? a) people need to learn how to spend more money instead of saving it. b) by knowing how much they spend, people can look for ways to save more. c) spending and saving habits cannot be changed, so people have to earn more. d) a personal budget shows people how to spend more money on items they want.

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.

step-by-step explanation:

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
