Answer: D

Step-by-step explanation:

If after 5 seconds the height was 20 feet then  in 10 seconds it will be 40 feet  and in 20 seconds it will be 80 seconds.

To get from 5  to 10 you multiply by 2

To get from 20 to 40 you multiply by 2.

Since you have a constant change then it works for D only.

Find the intercepts and graph the equation. 7x +5y=12
vazorg [7]

Answer:

y-intercept: (0, 12/5) or (0, 2.4)

x-intercept: (12/7, 0) or (1.714, 0)

Step-by-step explanation:

The y-intercept is the point where the graph crosses the y-axis. That means, the point (0, yi). To find yi, we have to substitute x by 0 in the equation.

7x + 5y=12

7*0 + 5y = 12

y = 12/5 = 2.4

y-intercept: (0, 12/5) or (0, 2.4)

The x-intercept is the point where the graph crosses the x-axis. That means, the point (xi, 0). To find xi, we have to substitute y by 0 in the equation.

7x + 5y=12

7x + 5*0 = 12

x = 12/7 = 1.714

x-intercept: (12/7, 0) or (1.714, 0)

Finally, the graph is shown below.

Answer:

For the part that contains organic matter your answer is, 35 negative result

For the part that does not contain organic matter your answer is, 60 positive result

Step-by-step explanation:

If we pay attention to the part that contains organic matter the total amount 700 and 665 is positive, so subtract them 700-665 to get 35 negative result

For the part that does not contain organic matter the total amount is 300, and 240 of it is negative, so subtract 240 from 300 to get 60 positive result

Your Welcome, Hope This Helps, And Have an Awesome Day!!!
