Which process contributes to the formation of tornados? a. water droplets freeze, giving off energy b. the storm begins to rotate around a central eye c. warm air rises, resulting in a decrease in air pressure. d. a cold, dry air mass interacts with a warm, moist air mass

D. A cold, dry air mass interacts with a warm, moist air mass.

Step-by-step explanation:

Tornadoes are very scary and kind of cool to look at. They have a great scientific reason behind them which we can easily understand.  First, a funnel cloud forms that reaches down to the ground (you probably have seen this in video as a cloud that is heavily densed and circling). Then , warm air rises, resulting in a decrease in air pressure and finally, a cold, dry air mass interacts with a warm, moist air mass.

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
