- Solving systems of equations by graphing
Step-by-step explanation:
We will have 1 solution set when the lines cross once.
We will have no solutions when the lines are parallel.
We will have infinite solutions when the lines are the same.
According to the graph, we see that our lines only intersect once at 1 point. Therefore, there will be only 1 solution.

I think they will meet in 4 minutes.
Explanation
10+15+15+15+15=70
150-20-20-20-20=70
Every minute the first balloon goes up 15 meters and the second balloon goes down 20 meters.
Here we see that the number 27 is closer to 30 than 20. Here we cannot see whether 25 is closer to 20 or to 30. If the digit following the rounding place is 0, 1, 2, 3, or 4, we round down. If the digit following the roundingplace is 5, 6, 7, 8, or 9, we round up.
