How can you find the value of the expression -5+12+10-7

First u take the negs and normal numbers and add them in separate groups then add the two last numbers together and which is bigger neg or normal is the one is ur answer

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
