Which equation has the components of 0= x2 - 9x - 20 inserted into the quadratic formula correctly?

x= -91V(-9)2 - 4(1)(-20) over
2(1)
x= 9:V(- 9)? – 4(1)(20) over
2(1)
x = 9:V(- 9)2 – 4(1)(-20) over
2(1)
x= -9+7 (-9)+ 4(1)(-20) over
2(1)

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
