The horizontal axis of the graph represents time, from 65,000 BCE (Before Current Era) to the present. Periods of 5,000 years are separated by vertical lines.
The vertical axis shows the total size of the world population, which has grown spectacularly over the period. Between 50,000 BCE and the present day, the number of human beings has risen from around 600,000 to 6.5 billion, a ten thousand-fold increase.
If that helps :)
Answer:
![y=-2.5x-9](https://tex.z-dn.net/?f=y%3D-2.5x-9)
Step-by-step explanation:
One is given the following equation.
![5x + 2y = 12](https://tex.z-dn.net/?f=5x%20%2B%202y%20%3D%2012)
The problem asks one to find a line that is parallel to this one, and passes through the point:
. The equation of the given line is in the standard format. The easiest approach to solve this problem is to change the equation of the given line into the slope-intercept format. The solve intercept format follows the following general equation:
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
Where (m) is the slope of the line and (b) is the y-intercept. Manipulate the given equation such that it follows this format:
![5x+2y=12\\2y=12-5x\\y=6-2.5x\\\\y=-2.5x+6](https://tex.z-dn.net/?f=5x%2B2y%3D12%5C%5C2y%3D12-5x%5C%5Cy%3D6-2.5x%5C%5C%5C%5Cy%3D-2.5x%2B6)
One property of parallel lines is that they have the same slope. Therefore, if one uses the slope-intercept format to represent the slope of the parallel line, then one can state the following:
![y=-2.5x+b](https://tex.z-dn.net/?f=y%3D-2.5x%2Bb)
Substitute a given point on this line (
) , and solve for (b) to find (b):
![y=-2.5x+b\\(4)=-2.5(-2)+b](https://tex.z-dn.net/?f=y%3D-2.5x%2Bb%5C%5C%284%29%3D-2.5%28-2%29%2Bb)
Simplify,
![4=-2.5(-2)+b\\-4=5+b](https://tex.z-dn.net/?f=4%3D-2.5%28-2%29%2Bb%5C%5C-4%3D5%2Bb)
Inverse operations,
![-4=5+b\\-9=b](https://tex.z-dn.net/?f=-4%3D5%2Bb%5C%5C-9%3Db)
Substitute this back into the equation in slope-intercept form to find the equation of the parallel line:
![y=-2.5x-9](https://tex.z-dn.net/?f=y%3D-2.5x-9)
Answer:
(3V)/A = h
Step-by-step explanation:
V = 1/3 Ah
Solve the literal equation using inverse operations;
V = 1/3 Ah
*3 *3
3V = Ah
/A /A
(3V)/A = h
We have 3x+50=6x-10 subtracting 3x from both sides we get 50=3x-10. Now we add 10 to both sides to get 60=3x. Dividing both sides by 3 we get x=20.
