Write a rule to describe the transformation. A. rotation 90º clockwise about the origin B. rotation 180º about the origin C. rotation 90º counterclockwise about the origin D. reflection across y=x

. A. rotation 90º clockwise about the origin

Step-by-step explanation:

. A. rotation 90º clockwise about the origin

the function makes a strait line horizontally with no x intercept but a y intercept at 9.

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
