Yesterday, Chang planted 6 trees that were each 8 feet tall in his yard. Chang projects the trees to grow at the following annual rates over the next 5 years. Assume that x represents the amount of years from when Chang planted the trees. Which of the following equations represent the height of each of the trees in 5 years? Select all that apply. Help!!!!

Sagot :

Answer:

Sugar Maple

8 + 1.5x = 15.5

Fraser Fir

8 + 0.25x = 9.25

Sycamore

8 + 2.5x = 12.5

Red Maple

8x + 3 = 43

Oak

8 + 4x = 28

Linden

8x + 1.5 = 9.5

Step-by-step explanation:

i hope this helps!!

Answer:

I answered this question in another thread, I'll copy paste it here.

Sugar Maple

8 + 1.5x = 15.5

Fraser Fir

8 + 0.25x = 9.25

Sycamore

8 + 2.5x = 12.5

Oak

8 + 4x = 28

Step-by-step explanation:

It cannot be Red Maple or Linden, because they are multiplying the number of years by the height it already has. We are looking for the height it will have BASED on the rate that Chang calculated. Therefore, we are multiplying the RATE by the NUMBER OF YEARS (x).

It cannot be red maple or Linden because you are multiplying the height they already have, and not the rate it will grow by.

The right expression to represent the growth of Red Maple would be

8 + 3x = 23

The right expression to represent the growth of Linden would be

8 + 1.5x = 15.5

Therefore, again, these are the correct answer(s): Sugar Maple, Fraser Fir, Sycamore, and Oak.
