Answer:
Option D.
Step-by-step explanation:
A reflection is a mirror image across the a line of reflection. The image will be perpendicular to the line of reflection and equal distance from it as the pre-image is too. This means that point G will move horizontally across the y-axis the same distance it is currently from the y-axis. It is 2 units away from the y-axis so G' will be 2 units on the other side or -2. This makes G' (-2,2). Notice this is the same coordinates of G only multiplied by -1. When reflecting a shape across the y-axis, the x-coordinates of the points are multiplied by -1.
So G (2,2) becomes (-2,2).
So F (-2,-1) becomes (2,-1).
So H (4,-3) becomes (-4,-3).
C= 2(4 + 3)
this might be too complicated but C (Cooper's goldfish) equals 2 times 4 + 3
X + 17 = 3x -31 (opposite angles are equal)
x + 17 = 3x -31
31 +17 = 3x - x
48 = 2x
x = 24
