Graphing the system of equations is shown in figure attached.
Solution set is (2,-4). The lines will intersect at (2,-4)
Step-by-step explanation:
We need to graph the system of equations. 
First we will find value of x and y
Let:

Add eq(1) and eq(2)

Putting value of x in eq(1) and finding y

So, y=-4

The temperature went down by 12 degrees. (Or you could say it changed by -12 degrees)
Answer:
5x?=30 and ?x5=30
Step-by-step explanation:
First of, these 2 are both the same, and the communitive property applies to both.
The question example is in division, since the communitive prop. doesn't apply on division, it would be almost impossible to find another answer in division form. 5x? Is asking 5 times what equals thirty, so we are using what we know to figure it out. Sorry, I can't provide a good explanation :<
Answer:
B IS THE ANSWER
Step-by-step explanation:
Answer:
The answer is D.
Step-by-step explanation:
The plots are going down to the right, showing a negative slope. The plots are do not have the same x-axis/domain, so there is a linear asociation between the two.
