What is the value of y in the equation 6 + y = –3

Y= negative nine because what you do to one side you must do to the other and you have to get Y alone so subtract six from both sides and you Y= negative nine

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
