Which of the following shows the figure rotated 90 degrees counterclockwise around the origin and then reflected across the x axis?

A

Explanation:

Transformation rule : The coordinates change by the rule when the figure rotate 90 degrees about the origin is given by

Transformation rule: When the figure reflected across x- axis then the coordinates change by the rule

The given figure cut x - axis at x=3

The coordinates (3,0).

After 90 degrees rotation about origin the coordinates becomes (0,3).

After reflection across x- axis , the coordinates becomes (0,-3).

Only in first figure, there is (0,-3) .

Hence, the option A is true.

i think the answer is a, hope this is right, that would be my best guess.

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
