Which best describes the transformation?

a. the transformation was a 90° rotation about the origin.
b. the transformation was a 180° rotation about the origin.
c. the transformation was a 270° rotation about the origin.
d. the transformation was a 360° rotation about the origin.

In geometry, transformations are used to move a point or points from one position to another. The transformation of is a 90 degrees rotation about the origin.

Given that:

The transformation rule is:

When a point is rotated through

Such point has undergone a 90 degrees counterclockwise rotation.

Hence, option (a) is correct.

Correct answer is "A"

Step-by-step explanation:

It is a tranformation about 90° in anti-clock wise direction

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
