Write the english sentence as an equation in two variables. then graph the equation.

the y-value is eight decreased by the square of the x-value.

the sentence can be translated to the equation ?

use the graphing tool to graph the equation.

  y = 8 - x^2

Step-by-step explanation:

"Decreased by ..." means whatever follows is subtracted from whatever came before. "Is" means "equals." So, the square of the x-value (x^2) is subtracted from 8:

  y = 8 - x^2

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
