Answer:
<-7,-3>
Step-by-step explanation:
To write RS in component form we need to know how far to move over horizontally and then how many to move vertically.
Since horizontal movement is the x values, we subtract the x values of R and S first.
0 - 7 = -7
Since vertical movement is in the y values we subtract those next.
5 - 8 = -3
So written in component form we have <-7,-3>
Subtract the like terms to get your answer of y^2 - 4y - 6
5/12(poetry) + 2/5(biographies) = 25/60 + 24/60 = 49/60
60/60 - 49/60= 11/60
11/60 are the remainder of the books in the shipment.
