Question

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

The answer is C. because 1.5 is the height while x is next to it to show the multiplication of years to height

Answer 2

it grows 1.5 feet per year so multiply that by number of years (x)

1.5x

it started at 2 feet tall

so you would have 1.5x +2 ≥14

Answer is C. 1.5x + 2 ≥ 14
