Triangles APQR and AABC are congruent. The side length of each square on the grid is 1 unit. А C B A R Which of the following sequences of transformations maps APQR onto AABC? Sequence A Sequence B A 180° rotation about point R, then a translation 2 units to the right and 6 units up. A translation 4 units to the right and 6 units up, then a reflection over the horizontal line through point A.​

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17

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
