The height of a pelican as it swoops down to catch a fish in the lake is modeled by this equation, where x represents the time, in seconds, and y represents the height of the pelican, in feet.
At the same time, a second pelican flies in a straight line, modeled by this equation.
Which statement describes the number and viability of the system’s solutions?
A.
The system has two solutions, and both are viable because they result in positive values of time.
B.
The system has two solutions, but only one is viable because the other results in a negative value of time.
C.
The system has only one solution, and it is viable because it results in positive values of time.
D.
The system has only one solution, but it is not viable because it results in a negative value of time.

Mary beth used the mapping rule to find the coordinates of a point that had been rotated 90° counterclockwise around the origin. examine the steps to determine whether she made an error. m (3, –6) is rotated 90° counterclockwise. (x, y) → (–y, x) 1. switch the x- and y-coordinates: (6, –3) 2. multiply the new x-coordinate by –1: (6(–1), –3) 3. simplify: (–6, –3) .
