Four times the difference of a number and 5 is the same as 5 increased by four times the number plus five times the number

4*(x-5)+5=5+(4*x)+(5*x)

4x-20+5=5+4x+5x

-20+5=5+5x

-15=5+5x

-20=5x

-4=x

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.
