Ashley and Kristin are selling wrapping paper for a school fundraiser. Customers can buy rolls of plain wrapping paper and rolls of shiny wrapping paper. Ashley sold 4 rolls of plain wrapping paper and 3 rolls of shiny wrapping paper for a total of $68. Kristin sold 9 rolls of plain wrapping paper and 2 rolls of shiny wrapping paper for a total of $77. What is the cost each of one roll of plain wrapping paper and one roll of shiny wrapping paper?

4x+3y=68

9x+2y=77

plain= 5 shiny=16

Step-by-step explanation:

plain=x shiny=y

-1/3(x+1)^5

i’m pretty sure this is correct

step-by-step explanation:

rectangles are made up of 4 right angles, which means that a side and a base meet perpendicular to one another.   their slopes then have to reflect perpendicular slopes.   perpendicular slopes are opposite reciprocals of one another.   for example, if the slope of one line is +2/3, then the perpendicular slope to that would be -3/2.   so we look for that combination in our choices.

all of them satisfy that condition (so what's the question, i guess? )
