Question

Don't understand this at all and this is my last try at the test please help will fan and medal. Which inequality best represents the situation?
A pine tree grows at a rate of 1.5 feet per year. James plants a 2-foot tall pine tree in his yard. How many years will it take for the tree to be at least 14 feet tall?

A.
2x + 1.5 ≥ 14

B.
2x – 1.5 ≤ 14

C.
1.5x + 2 ≥ 14

D.
1.5x – 2 ≤ 14

Answer 1

I think it is D but i am not sure

Answer 2

Start at 2 (When x = 0, you just planted it, there is no annual growth.)
Increase 1.5 for every year that passes. (1 year 2.0 + 1.5, 2 years 2.0 + 1.5 + 1.5)
There is no subtraction. Only growth.

Which ones give 2 when x = 0? Throw out anything that doesn't.
Which ones have subtraction? Throw out anything that does.
