Answer: 
Step-by-step explanation:
ALRIGHT ARE YOU READY FOR EPIC MATH TIME?
because i know i am. so lets get this bread.
WATCH: we have 
interesting... that first character is called pi. maybe i should have said, "lets get this pi".
so now lets do some algebra. i am going to work from right to left. lets multiply 6r by 2. that gives us 12r. now we have... 
WE ARE MAKING EPIC PROGRESS, AREN'T WE?
lets multiply 12r by 3r. then we have....

notice how i multiplied 12 by 3 and also r by r (which gives 36 and
respectively)
so your simplified expression is: 
Answer:
(4,2)
Step-by-step explanation:
The solution to the system is where the two graphs overlap
The two graphs cross at x=4 y =2
(4,2)
150-25=125mph
130-25=105
This means it was going 125mph and that it dropped an altitude of 25 degrees because of the wind and the slow down of the helicopter
