Last year there were 15 porcelain dolls in lanny's collection, after trading for a rare doll, she now has 12 dolls. what is the percent decrease of her collection?

why can't you?

step-by-step explanation:

this shows a reflection over the x-axis and is translated one unit down and 6 units to the right (x + 6, y - 1)

hope this !

y > 1/3x

y < = -x + 4

hope this : )
