Use the graph to complete the statement. O is the origin. r(180°,O) ο Ry−axis : (2,5) A. ( 2, 5)
B. (2, -5)
C. (-2, -5)
D. (-2, 5)

9514 1404 393

  B.  (2, -5)

Step-by-step explanation:

Reflection across the y-axis is the transformation ...

  (x, y) ⇒ (-x, y)

Rotation 180° about the origin is the transformation ...

  (x, y) ⇒ (-x, -y)

Applying the rotation after the reflection, we get ...

  (x, y) ⇒ (x, -y)

  (2, 5) ⇒ (2, -5)

Additional comment

For these transformations, the order of application does not matter. Either way, the net result is a reflection across the x-axis.

can you post the graph?

so the rectangle is 80cm (area)

now to find the area of a triangle.

base times height.

4 times 8.

your answer is 96cm.

hope this .
