Answer:
I can't see the text can u post it so I can see it?
Explanation:
Answer:
x = -2, y = 1
Explanation:
Finding X:
3x + 4y = -2
2x - 4y = -8
5x = -10
5x/5 = -10/5
x = -2
Why: Using the elimination method, you can eliminate 4y and -4y since they are opposites. Then its an addition problem; 3x plus 2x is 5x. -2 plus -8 is -10. From there it's "junk and divide"
Finding Y:
2(-2) - 4y = -8
-4 -4y = -8
+4 +4
-4y = -4
-4y/-4 = -4/-4
y = 1
Why: Because you found that x = -2, you can then plug it in one of the equations. From there its simple "junk and divide". Hope this helps this took a long time to type lol.
Answer:
It would be very hard to move, the trains and/or busses would probably run late because of the amount of people.
If there is way to many people, people may get rowdy and starting getting angry at each other, possibly resulting in someone getting injured.
Oceans produce approximately 80 percent of the oxygen our planet needs to support animal life. Pollution that reaches the ocean through dumping, oil leaks, runoff, and other processes interferes with that oxygen production and poses a real threat to the oxygen content in our atmosphere. If the oxygen content decreases, it is likely that carbon dioxide will increase. This could have dramatic consequences for life as we know it.<span> </span>
