Question

Two students were testing the parachute designs they made for an egg-drop project. Both students dropped their eggs from a height of 10 feet. One design made the egg fall at a rate 5 feet per second, and the other design made the egg fall at a rate of 3 feet per second. If x represents the time in seconds that the egg falls and y represents the height of the egg, which system of equations represents the situation described? (1 point)
y = -5x
y =-3x

y = 5x - 10
y = 3x - 10

y = 10 + 5x
y = 10 + 3x

y= 10- 5x
y =10 - 3x

Answer 1

y = 10 - 5x
y = 10 - 3x

Explanation: starting height is 10 ft and height decreases at 5 ft/s or 3 ft/s, so y = 10 - (rate)x.
