The difference of the blue crab population From 1990-1997, the average was (800+750)/2 = 775; and from 1989-2009: (350+350)/2 = 350. I predict that from 2010 to 2020 the population will increase to about 500 because it seems to go on trends of increasing and decreasing.

Answer: x = -2

<u>Step-by-step explanation:</u>

vertical line means it will be x = ___

Set the x-values equal to each other and solve for x.

3 - 2x = x + 9

<u>    +2x</u> <u>+2x     </u>

3        = 3x + 9

<u>-9      </u>    <u>      -9 </u>

-6       =3x

    \frac{-6}{3} = \frac{3x}{3}

Write parametric equations of the line y=4x-5
Rasek [7]

Answer:

A set of parametric equations for the line y = 4x - 5 is;

x = t

y = 4t - 5

Step-by-step explanation:

To find a set of parametric equations for the line y = 4x - 5;

We can assign either variable x or y equal to the parameter t, in this case we can easily let x = t

We then substitute x = t in the original equation;

y = 4t - 5

Therefore, a set of parametric equations for the line y = 4x - 5 is;

x = t

y = 4t - 5
