The change in temperature is +30ºC. The way I got this is that to get from -17ºC, I have to add that same number to get 0 - +17ºC. Now, I add +13, to get +13ºC. Hence, the change in temperature is +30ºC. Expression: (-17) + (+30) = (+13)

Iwould think that the correct answer is 8.1

Answer might be d.i think

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
