Which of the following does not describe the dependent variable?
a. it is the range.
b. it is the y-values.
c. it is the output.
d. it is the x-values.

The proper answer is D, it is the x-values. Those values are the independent ones, so they can't describe the dependent variable.

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
