Answer:

Step-by-step explanation:

5x + 2y = 20

Here we will show you how to calculate the following:

Calculate and show the solution for the x-intercept and y-intercept of 5x + 2y = 20.

Calculate the graph plot coordinates for 5x + 2y = 20

Solve 5x + 2y = 20 for x and also for y.

Calculate and show the solution for the slope of 5x + 2y = 20

Find x-intercept

The x-intercept is where the graph crosses the x-axis. To find the x-intercept, we set y1=0 and then solve for x.

5x + 2y = 20

5x + 2(0) = 20

x1 = 4    y1 = 0

Find y-intercept

The y-intercept is where the graph crosses the y-axis. To find the y-intercept, we set x2=0 and then solve for y.

5x + 2y = 20

5(0) + 2y = 20

y2 = 10    x2 = 0

 

Get Graph Plot Coordinates

Getting two graph points will allow you to make a straight line on a graph. The plot coordinate format is (x1,y1) and (x2,y2).

Thus, we use the x-intercept and y-intercept results above to get the graph plots for 5x + 2y = 20 as follows:

(x1,y1) and (x2,y2)

(4,0) and (0,10)

Find slope

The slope of the line (m) is the steepness of the line. It is the change in the y coordinate divided by the corresponding change in the x coordinate. Simply plug in the coordinates from above and solve for m to get the slope for 5x + 2y = 20

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

m = (10 - 0)/(0 - 4)

m = -2.5

Answer:

V = 2143.57

Step-by-step explanation:

To find the volume of a sphere you need to use this formula:

V = \frac{4}{3}\pi r^{3}

r = radius

Solve:

You need the radius from the diameter. Divide 16/2 which is

8.

V = \frac{4}{3}(3.14) 8^{3}

V = 2143.57
