One way is by comparing the weather for today as compared to the rest of the week or month.
For question 4 the Y needs to be by itself. So instead of it being x+2y>/-12 it would be y>/-6+x. You would have to subtract x on both sides and then divide 2 on both sides as well. whatever you do on one side, you have to do it on the other side. Hope this helps. After you redo all the equations, you graph them. If you need anymore help , let me know!
Answer:
(-2, -4.5) is the answer!
I hope this helps!
1) (-7)3
2) PEMDAS; simplify (5-3)
3) 5^3, 5x5x5 and 125
4) -8^4
5) 36
6) 7
7) -100
8) 30
There ya go! Pretty sure they're all right!
