If 3 times a number minus 2 equals 13, what is the number?
a. 4
b. –6
c. 5
d. 2

3x - 2 = 13
    + 2   + 2
     3x = 15
      3      3
       x = 5

The answer is C.

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
