The deck of a ship is 7 feet above the surface of the water. There is also a cabin that is 14 feet below the deck. Which number describes
the elevation of the cabin?
Note: Your answer is expected to be a number without units for this
problem

-7 feet because 0 is water level and the deck of the ship is 7 feet above eatet and the cabin is 14 feet below the deck so you subtract 14 from 7 and get -7 (7-14=-7)

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
