The clear rendering however reads;
What does the graph on the first page of this class reveal about the demand for oil over time?
Explanation:
Since the graph is not provided, note the following about demand curve (graph). A demand graph is diagrammatic representation of how demand changes over time.
Thus, demand is usually plotted against price. I'll recommend you look carefully at the trend of the graph to find rising peaks and falling peaks which would indicate if demand is stable or not.
Answer:
D
Explanation:
They both have large storm "spots" :)
OA ocean winds blow consistently, providing a cooling effect
Answer:

Explanation:
Given
Parallel to: 
Passes through (-9,-4)
Required
Determine the line equation
First, we calculate the slope (m) of the said line

Make y the subject

Divide through by 3

An equation has the general form:

Where

So:

Because the required line is parallel to
, then they have the same slope of 
Next, is to calculate the line equation using:

Where


This gives:


Open bracket


The answer is; Atmospheric circulation patterns keep the temperature of an area constant.
The atmospheric circulation does not keep the temperatures in an area constant, however, they regulate temperatures through convection currents. Hot air rises as cold air mass sinks to replace the rising hot less dense air. These currents transfer energy around the globe and prevent one area from overheating.
