The air plane is rising so the change in elevation is +1000 feet. The temp dropped and is -20 degrees fahrenheit.
1 degree per 50 ft
For every 1,000 feet that it climbs, the outside temperature drops 20 ... What is the rate of temperature change in degrees Fahrenheit per foot.
ANSWER
(6,-5)
EXPLANATION
The given system has equations:
2x + y =7...(1)
x- 2y = 16...(2)
We multiply equation (1) by 2 to get,
4x+2y=14...(3)
We add equations (2) and (3) to obtain,
4x+x+2y-2y=14+16
This implies that,
5x= 30
Divide both sides by 5,
x=6
We substitute x=6 into equation (1) to get,
2(6) +y=7
12+y=7
y=7-12
y=-5
The solution is (6,-5)
