A plane is 20,000 ft. In the air and descending at a rate of 25 ft. Per minute. Write an equation to represent this situation where y is the height of the plane after x minutes.

Step-by-step explanation:

Step one:

given data

initial height of plane= 20000ft

rate of descending= 25ft per minute

let x be the number of minutes it took the plane to descend

and let y be the height after x minutes

Step two:

Required

the mathematical expression for the height

the expression for the situation mathematically is

y=20000-25x
