Answer:
![(x,y) = (-4,2)](https://tex.z-dn.net/?f=%28x%2Cy%29%20%3D%20%28-4%2C2%29)
Step-by-step explanation:
Given
![x + y = -2](https://tex.z-dn.net/?f=x%20%2B%20y%20%3D%20-2)
![y = 2x + 10](https://tex.z-dn.net/?f=y%20%3D%202x%20%2B%2010)
Required
Determine the point of intersection of both equations (if graphed)
To do this, we solve for x and y
Substitute 2x + 10 for y in the first equation
![x + 2x + 10 = -2](https://tex.z-dn.net/?f=x%20%2B%202x%20%2B%2010%20%3D%20-2)
![x + 2x = -2 - 10](https://tex.z-dn.net/?f=x%20%2B%202x%20%3D%20-2%20-%2010)
![3x = -12](https://tex.z-dn.net/?f=3x%20%3D%20-12)
![x = -4](https://tex.z-dn.net/?f=x%20%3D%20-4)
Substitute
in the second equation
![y=2x +10](https://tex.z-dn.net/?f=y%3D2x%20%2B10)
![y=2*-4 +10](https://tex.z-dn.net/?f=y%3D2%2A-4%20%2B10)
![y=-8 +10](https://tex.z-dn.net/?f=y%3D-8%20%2B10)
![y = 2](https://tex.z-dn.net/?f=y%20%3D%202)
So, the point of intersection is:
![(x,y) = (-4,2)](https://tex.z-dn.net/?f=%28x%2Cy%29%20%3D%20%28-4%2C2%29)

Answer:
warmer by 30.2 degrees
Step-by-step explanation:
It might help to think of these values plotted on a number line. Both temperatures will be left of zero, with -63°C being farther to the left (colder).
The difference can be found by subtracting the colder temperature from the warmer one:
-32.8 -(-63) = -32.8 +63 = 63 -32.8 = 30.2 . . . degrees
The South America temperature -32.8°C is 30.2° warmer than the North America temperature.
