Identify all of the linear functions

2x + 5y = 13

-x^3=3y+10

3(2x^4+y)=14

y=13-2x^2

2=y+x^5

y=x+7

2x + 5y = 13  and  y=x+7

Step-by-step explanation:

Linear functions are characterized by "first power" for both x and y.

The following equations satisfy that requirement and are thus linear:

2x + 5y = 13

y=x+7

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
