According to modern science, earth is 4.5 billion years old and written human history extends about 10,000 years back. suppose the entire history of earth is represented with a 1000 meter long timeline, with the birth of earth on one end and today on the other. what distance represents 4 billion years? how far from the end of the time line does written human history begin?

Step-by-step explanation:

Length is proportional to time, so ...

1. (4 billion)/(4.5 billion) = L/(1000 meters)

... L = (1000 meters)×4/4.5 = 888 8/9 meters

2. Using the same idea as in problem 1, the length is ...

... L = (1000 meters)×(10^4)/(4.5×10^9) = (2 2/9)×10^-3 meters = 2 2/9 mm

You must have wrote the equation incorrectly

Step-by-step explanation:

You wanna make f(x) equal to 6

So its 6 = 2x + 57

Subtract 57 from both sides to get -51 = 2x

Divide both sides by 2 to get -25.5
