which ordered pair belongs to the solution set of the equation y = x2 - 2x + 1?
a. (510)
b. (-1,3)
c. (1,2)
d. (3,4)

B and D

Step-by-step explanation:

To determine which point is a solution, substitute the x- coordinate into the right side of the equation and if the value obtained agrees with the y- coordinate then it is a solution.

(5, 10)

y = 5² - 2(5) + 1 = 25 - 10 + 1 = 16 ≠ 10 ← not a solution

(- 1, 3)

y = (- 1)² - 2(- 1) + 1 = 1 + 2 + 1 = 3 ← This is a solution

(1, 2)

y = 1² - 2(1) + 1 = 1 - 2 + 1 = 0 ≠ 2 ← not a solution

(3, 4)

y = 3² - 2(3) + 1 = 9 - 6 + 1 = 4 ← this is a solution

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
