Simplify -5(4y-7x)+8(3x-2y)

59x-36y

Step-by-step explanation:

-5(4y-7x)+8(3x-2y)

Open the brackets

-20y+35x+24x-16y

Collect like terms

-20y-16y+35x+24x

-36y+59x

Rearrange we get

59x-36y

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them.   .

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
