Help pls *giving brainliest*

Answer:
Don't worry! This is not that hard! You got this! You can use this for checking :)
Plus we have to use x-y and use the numbers given for each question
15. x-y if x=6 and x=-3
6-(-3) negative plus negative equals positive
6+3= 9
16. x= -7 x=1
-7-1= -8
17. x=-2 y=-6
-2-(-6) negative plus negative equals positive
-2+6= 4
18. x=9 y=11
9-11= -2
19. x=-1 y=-1
-1-(-1)
-1+2= 1
20. x=-5 y=5
-5-5= -10
21. The high temp. is 6 and the low temp. is -3 It sasking for the differnece between the two.
6-(-3)
6+3=9
The difference between the high temp. and low temp. is 9 degrees Fahrenheit
22. This question is a little tricky but don't worry!
From -7 to 7. To reach -7 to 0, that is 7 degrees. To reach 7 from 0, that is also 7 degrees. So you add 7 and 7!
7+7= 14
The temperature increased 14 degrees Fahrenheit.
Hope this helps! Good luck on your quiz and I hope you pass :)
