Answer:
y= 50 + 4x, 130 meters and 82 meters.
Step-by-step explanation:
Given, a balloon is released from a 50 meter tall building and rises at the rate of 4 meters per second. So, the equation will be y = 50 + 4x, where x is time in seconds.
So, after 20 seconds, the balloon will be at
y = 50 + 4x= 50 + 4 X 20 = 50+ 80= 130 meters. Here, x = 20 seconds.
For, x = 8 seconds,
y = 50 + 4x= 50+4 X 8 = 50+32= 82 meters. So the balloon will be at 130 meters and 82 meters respectively.
