Answer:

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

<u>Sugar Maple</u>

8 + 1.5x = 15.5

<u>Fraser Fir</u>

8 + 0.25x = 9.25

<u>Sycamore</u>

8 + 2.5x = 12.5

<u>Oak</u>

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 <u><em>will have</em></u> BASED on the <u>rate</u> that Chang calculated. Therefore, we are <em>multiplying</em> the RATE by the NUMBER OF YEARS (x).

It <u>cannot</u> be <em>red maple </em>or<em> Linden </em>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 <u>correct answer(s)</u>: Sugar Maple, Fraser Fir, Sycamore, and Oak.

Which graph represents the inequality y&gt;1-3x
slava [35]

Answer:

b............ .......... which one is a b c d

For this case we must indicate the graph of the following inequality:

y≥1−3x

It is observed that inequality includes equality, so the boundary line of the graph will not be dotted, so we discard options D and C.

We test option A, we substitute the point (0,0) in the inequality, if it is fulfilled then the graph corresponds to it.

We test option A, we substitute the point (0,0) in the inequality, if it is fulfilled then the graph corresponds to it.

It is not fulfilled

We test the last option B, we choose the point (3,1) that belongs to the graph:

1≥1−3(3)

\1≥1−9

1≥−8

it is fulfilled
