2. A penguin is sitting on an iceberg 157 feet above the water. If a walrus is in the water 312 feet from the base of the iceberg, what is the angle of depression from the
penguin to the walrus?

Graph the equation by plotting point x=2

Select the correct answer from the drop-down menu. subtracting 3xy^2 from 8xy^2 gives the same result as the expression. [tex]3xy ^{2} - 8xy ^{2} [/tex][tex] { - 7xy}^{2} - {2xy}^{2} [/tex][tex] {7xy}^{2} - {2xy}^{2} [/tex]

Which equation results from adding the equations in this system? x+6y=9 and -x+2y=-15
