• Question 1
30 seconds
Q.

A balloon is released from the top of a building that is 50 meters tall. The balloon rises at the rate of 4 meters per second. Which equation represents the situation?

y = 4x + 50

y = - 4x + 50

y = 50 - 4x

y = 4x - 50

• Question 2
30 seconds
Q.

An airplane is flying at 20,000 ft and needs to ascend up to 35,000 ft to avoid a storm that is up ahead. The plane rises at a rate of 3,000 ft per minute. Which equation shows the height H of the plane after x minutes

H = 3,000x + 20,000

H = 3,000x + 35,000

H = 20,000x + 3,000

H = 35,000x + 3,000
