REALLY NEED SOMEONE TO HELP ME!!!! Which sequence of transformations was performed on figure PQRS to produce figure PꞌꞌQꞌꞌRꞌꞌSꞌꞌ? A. PQRS was reflected across the y-axis and then rotated 90° counterclockwise about the origin. B. PQRS was reflected across the x-axis and then rotated 90° counterclockwise about the origin. C. PQRS was translated 5 units left and then reflected across the x-axis. D. PQRS was rotated 180° clockwise around the origin and then translated 1 unit left.

    90 counterclockwise \[\large\rm (x,y) ----> (-y,x)\] 90 clockwise \[\large\rm (x,y)----->(y,-x)\] 180 clockwise \[\large\rm (x,y)---->(-x,-y)\]

    yea you are right sorry for late i was did something wrong and here is an explanation for A so first we have to rotate across the y -axis to do that we have to y -coordinate stays same like in original image and change the sign of x coordinate so in the original image P (1,2) Q(3,1) R(3,3) S(1,4) rotate over y-axis like i said y values stay same change sign of x coordinate P(-1,2) Q(-3,1) R(-3,3) S(-1,4)|dw:1434320428977:dw| now we have to use those definitions

    after reflection P(-1,2) P''(-2,-1) Q(-3,1) Q''(-1,-3) R(-3,3) R''(-3,-3) S(-1,4) S''(-4,-1) \[\large\rm 90-countercloskwise (x,y)---->(-y,x)\] so yeah that's how A is right
