PLEASE HELP WITH THIS QUESTION ASAP Sketch y > xy (I know how to sketch the inequalities when there is 2 variables bit not like this)

Step-by-step explanation:

y>xy

or xy<y

or y(x-1)<0

so y and x-1 are of opposite sign.

let y>0

then x-1<0

or x<1

case ii. if y<0,x-1>0

or x>1

so we conclude if x<1,y is positive

and if x>1,y is negative.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
