Question

First equation: y = -20x+800

fourth equation y = 30x

when will the first and fourth balloons be at the same altitude? What is that altitude? what does this mean graphically

Answer 1

Hello, last one? Lol

Explanation:

The first balloon is descending from the point of 800 meters whereas the 4th balloon is ascending from the ground. This means graphically, that 1 line has a negative slope, and one has a positive slope. Both lines cross at the point (16,480), or 16 seconds, 480 meters.

Hope you understand!
