Answers

Answer:

Although many factors combine to influence weather, the four main ones are solar radiation, the amount of which changes with Earth's tilt, orbital distance from the sun and latitude, temperature, air pressure and the abundance of water.

The regional atmosphere and regional weather are highly interactive phenomenons of any larger climate type.

A change in the atmosphere due to certain externalities promptly exhibits a change in the weather of the region.

This is primarily because of the fluctuations that take place in atmospheric factors like that of temperature and air pressure.

Temperature directly governs the humidity of a region whereas air pressure is responsible for the precipitation actions.

Use the table below to determine whether f(x) could represent a linear function. If it could write f(x) in the form f(x) = mx +b.

Answers

Answer:

5x-3

Step-by-step explanation:

This is linear because the numbers are changing at a constant rate (of 5)

We can also see that when x=0 y= -3 which means that in our equation

y=mx+b

-3 =b

I said prior that the rate of change is 5 which means that our slope is 5

which means that our equation looks like
