Tina sells lampshades for $7 each and paper lanterns for $4 each at a one-day craft fair. she sells k lampshades and (k + 4) paper lanterns. the expression 7k + 4(k + 4) represents tina’s total sales.
select all the equivalent expressions for tina’s total sales at the fair.
a 8k+16 b 11k+4
» 11k+16 d 7k+4k+4
» 7k+4k+16. how is it equivalent?

4xk = 4K 4x4= 16 +4K + 7k = 16+ 11k ( I would double check me

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.

in conclusion, "ppl are so gay" due to their genetics.
