A figure is rotated 270 degrees counterclockwise about the origin. Then the image is rotated 90 degrees counterclockwise about the origin. Complete the coordinate notation that represents the series of rotations. What can you conclude about the position of the figure after the series of rotations?

If you don't mind, I need the answer ASAP

The coordinate notation that represents the series of rotations is (x, y) → (y, -x) → (-y, x).

The total rotation is , so the figure is at the same position,

In Mathematics, a rotation is a type of transformation which moves every point of the object through a number of degrees around a given point, which can either be clockwise or counterclockwise (anti-clockwise) direction.

For instance, we would apply a rotation of 270 degrees counterclockwise about the origin to point A (1, 2);

(x, y) → (y, -x)

A (1, 2) → A' (2, -1)

By applying a rotation of 90° counterclockwise around the origin to the new point A', the coordinates of its image are as follows:

(x, y) → (-y, x)

A' (2, -1) → A" (-(-1), 2) = (1, 2).

In this context, the total rotation is given by;

Total rotation = 360° - (270° + 90°)

Total rotation = 0°

In conclusion, the figure would remain at the same position because the series of rotations has a total rotation of zero degrees.
