What is the value of k? 2k+9=7−3k a) −2 b)−0.4 c)2 d)3.2

2k + 9 = 7 - 3k
2k + 3k = 7 - 9
5k = - 2
k = - 0.4

the answer is B

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
