The two expressions below are equivalent.
y(2.5+7)+y−2
10.5y−2
Which statement best explains why the expressions are equivalent?

A. The expressions have the same value for any value of y .
B. The expressions have the same value for only whole number values of y.
C. The expressions have the same value only when y is an odd number.
D. The expressions have the same value only when y is an even number.

The correct answer is $90

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
