The balloon ascended 1300ft.
WORK:
3*60=180
180+15=195
195/60=3.25
3.25*400=1300
That is why your answer is 1300ft. Enjoy!

can also be written as 2i
where i = √-1

Rationalizing denominator,
Answer:
y = 3x - 1
Step-by-step explanation:
Although the coordinate plane is not given, we don't need it to find the solution. We have given all the conditions enough for the solution.
The y-intercept is (-1) and the function passes through the point ( 1, 2 ).
Only the function y = 3x -1 matches these conditions.
We can observe the points in the attached graph.
