A plane descends from an altitude of 5,000 feet at a rate of 300 feet per minute for the first five minutes. after this, the plane descends at a rate of 200 feet per minute until it touches down on the ground. what is the altitude of the plane when the plane has been in descent for 7 minutes.

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

a is the right answer

c
