What is the rule for the reflection? a. ry-axis(x, y) → (–x, y) b. ry-axis(x, y) → (x, –y) c. rx-axis(x, y) → (–x, y) d. rx-axis(x, y) → (x, –y)

D. .

Step-by-step explanation:

We have been been given an image of reflection on coordinate plane and we are asked to find the rule for the given reflection.

Upon looking at our given image, we can see that its vertices are A(-1,0), B(0,2), C(3,2) and D(4,0).

The vertices of pre-image are A'(-1,0), B(0,-2), C(3,-2) and D(4,0).

Since the x-coordinate are same and y-coordinates has changed to their opposite sign, therefore, the given image is reflected across x-axis to get the pre-image.

The rule of reflection an image across x-axis is .

Therefore, option D is the correct choice.

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
