A plane flew to an altitude of 8,000 feet. Two minutes later, its altitude was 12,000 feet. What was the average change in elevation per minute? ___ miles per minute

2,000 altitude and 3,000 descents per minute.

Step-by-step explanation: Because if 8,000 then in two minutes is was at 12,00 then that means 8,000 plus 4,00 is 12,000 so divide 4,000 by 2 and you get 2,000 in a minute.

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571

step-by-step explanation:

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
