Answer:

Find x if the slope between (7,-9) and (x,-13) is -1/3

slope between two points:

slope = (y2 - y1)/(x2 - x1)

plug the given data from the problem and solve for x:

-1/3 = (-13 - (-9))/(x - 7)

-1/3 = (-13 + 9)/(x - 7)

-1/3 = (-4)/(x - 7)

cross -multiplying:

3(-4) = -1(x-7)

-12 = -x+7

-19 = -x

19 = x

Scientific Question: How does the amount of soil carbon change with decreasing
svetoff [14.1K]

The averages allow us to understand the influence of the mangrove on the fixation of organic carbon in the soil.

By reducing the mangroves, the organic carbon in the soil also decreases

Mangroves are an ecosystem formed by species resistant to salt, called mangroves, located near the mouth of rivers and near the sea; a large amount of organic matter is produced in the process that increases the amount of carbon in the soil.

The best method to analyze the amount of carbon in the soil according to the distance from the mangrove to the interior humidities is by taking an average of each measurement

Zone closest to the coast

Sample     Proportion of organic carbon in the soil

   1                 0.258

   2                0.354

   3                0.333

   4                0.298

   5                0.337

Average value

          Avg _{Close } = 0.316

Intermediate zone

Sample  Organic carbon production

   1           0.274

   2          0.369

   3          0.384

   4          0.379

   5          0.370

Average value

      Avg_{Intermediate} = 0.355

Zone far from the coast (inland)

 Sample    Organic carbon production

     1            0.158

     2           0.185

     3           0.179

     4           0.212

     5           0.084

Average value

    avg_{ Far} = 0.164

When analyzing the average values, it is observed that the farthest part of the mangrove the amount of carbon in it is the smallest and as we do not approach the mangrove area the amount of carbon is practically constant.

In conclusion, the averages allow us to understand the influence of the mangrove on the fixation of organic carbon in the soil.

By reducing the mangroves, the organic carbon in the soil also decreases

Solve the following systems of 3-variable linear equations.​
Zina [86]

Answer:

x = 9/25, y = 7/25, z = 4/25

Explanation:

step 1: solve for y in first equation to use substitution

y = -2x + 1

step 2: insert into second equation to eliminate y variable and work with two variables

3(-2x+1) + z = 1 (now distribute)

-6x + 3 + z = 1 (bring over the -3)

-6x + z = -2

step 3: now left with -6x + z = -2 and x + 4z = 1, so eliminate z

-6x + z = -2 (multiply by 4)

4(-6x + z = -2)

-24x + 4z = -8

-

x + 4z = 1 (brought down third equation)

-25x = -9

x = 9/25

then just plug in x into the third equation to solve for z, followed by plugging it into the first equation to solve for y. you should end with y = 7/25 and z = 4/25
