Identify as a direct variation, inverse variation or neither. the number of tons of coal burned by an old coal burning locomotive under given conditions varies as the number of hours.

it is a direct variation.

Justification:

In a direct variation the variables are related by a proportionality constant in this way:

y = k x

Tthan means that the value of y is always the product of a constant times the value of x.

The situation discribed for the coal may be written as:
number of tons of coal burned: c

number of hours: h

⇒ c = k × h

Which is that you can calcualte the number of tons of coal burned at any time, once you know the proportionality constant k.

The answer is harsh laws are needed to control the society
