35 points and brainliest! Kim performed a transformation on triangle ABC to create triangle A'B'C', as shown in the figure below: What transformation did Kim perform to create triangle A'B'C'? A)Reflection across the x‐axis B) Rotation of 270 degrees counterclockwise about the origin C)Reflection across the y‐axis D) Rotation of 90 degrees counterclockwise about the origin

C) Reflection across the y-axis

Step-by-step explanation:

This is a reflection across the y-axis because the only coordinates that stay the same for the triangle A'B'C' are the ones on the y axis. You can also tell that it is a y-axis reflection because all values on the x axis are flipped. For example C starts as (-2,8) then becomes (2,8).

i took this test abt 3 weeks ago and this correct answer my friend is C reflect across the y-axis

Step-by-step explanation:

3 4 7 12 19

+1 +3 +5 +6

i would guess 26 because this isnt a sequential pattern or its to short to know
