Triangle ABC underwent a sequence of transformations to give triangle A′B′C′. Which transformations could not have taken place?

A.
a reflection across the line y = x followed by a reflection across the line y = -x

B.
a reflection across the x-axis followed by a reflection across the y-axis

C.
a rotation 180° clockwise about the origin followed by a reflection across the line y = x

D.
a reflection across the y-axis followed by a reflection across the x-axis

f

step-by-step explanation:

f

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4

step by step solution :

step   1   :

1.1     4 = 22

(4)3 = (22)3 = 26

equation at the end of step   1   :

  ((23) • 26)2

step   2   :

equation at the end of step   2   :

  (23 • 26)2

step   3   :

final result :

  218
