Mathematics: What are two possible transformations that together could have been used to create the red figure from the blue figure? a) a reflection across the x axis followed by a reflection across the y axis b) a translation of 1 unit down followed by a rotation of 90 degrees clockwise about the origin c) a rotation of 90 degrees counterclockwise about the origin followed by a reflection across the x axis d) a rotation of 90 degrees counterclockwise about the origin followed by a translation of 1 unit down

I think its either C or D give me one second to figure it out.

C) a rotation of 90 degrees counterclockwise about the origin followed by a reflection across the x axis

Step-by-step explanation:

Since, when the figure is rotated 90 degree counterclockwise about the origin,

Then the new coordinates are,

$(1,0)\rightarrow (0,1)$

$(2,0)\rightarrow (0,2)$

$(4,1)\rightarrow (-4,1)$

$(4,3)\rightarrow (-4,3)$

Now, When the transformed figure again reflected across the x axis,

Then the coordinates of final figure are,

$(0,1)\rightarrow (0,-1)$

$(0,2)\rightarrow (0,-2)$

$(-4,1)\rightarrow (-4,-1)$

$(-4,3)\rightarrow (-4,-3)$

Which are the coordinates of the red figure,

Thus, Option C is correct.

Free yet powerful Solver Simplifier that Shows Work ... ... Step 2 : Trying to factor as a Difference of Squares : 2.1 Factoring: 36c2-121 ... Note : - AB + AB equals zero and is therefore eliminated from the expression
the answer would be 2.1 according to this
