Find the composition of transformations that map ABCD to EHGF. Reflect over the -axis, then translate (x+ ,y+)

(x+2,y+4)

9514 1404 393

  (x+ (-4), y+ (-4))

Step-by-step explanation:

After point D is reflected across the y-axis, its coordinates are ...

  D(-1, 2) ⇒ D'(1, 2)

This is the point that gets translated to F(-3, -2). The translation is ...

  F -D' = (-3, -2) -(1, 2) = (-3-1, -2-2) = (-4, -4)

Then the translation rule is ...

  (x, y) ⇒ (x+(-4), y+(-4))

answer: i cant see the graphs but i can you find the answer

step-by-step explanation:

the first point we'll be 0,0 and then you go up the y axis 4 places and over to the right 1 so your second point will be 1,4

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
