Question

PLEASE HELP

The altitude of a plane as it begins to descend is shown by the linear equation
A = 22,000 - 800m, where A is the plane's altitude, in feet, and M is minutes.
What's the planes altitude when M = 12?

Answer 1

just replace m in the equation by 12 and work it out

A = 22,000 - (800*12)

Answer 2

work out what's in the brackets first

Answer 3

so i multiply 800 x 12?

Answer 4

do that first then subtract your answer from 22,000
