Just need a little help

D original(3,-1) > 'D' New [The Reflection] (3,1)  C original (-1, -1) > 'C' New (1,-1)  E Original ( -4, -4) > 'E' New (4, -4)

Step-by-step explanation:

Hi! Count from the starting point to the new reflected point for each coordinate. (for example, Point D to the Y axis. Point D moving towards the Y axis (the line marked Y) is 3 units to the right. You would mimic that on the other side of the axis. So, from the right side of the axis, you would move 3 units to the left and that would be your new 'D'.

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
