This is a guess, but, from what I've researched, maybe decrease? I've looked into it alot and that's just I think, though, it may depend on the previous height. Still, just an educated guess (I've got 100% on all kinds of quizzes because of educated guesses so, it may work!)
Since you are not given any values to plug in, solving for c simple means to isolate c. First, you would subtract 32 from both sides to get F-32=9/5C. Then, you would multiply both sides by 5/9 in order to get 5/9(F-32)=C or 5/9F-160/9=C.
Hope this helps.
1. √169 = √(13 · 13) = 13
2. √169 = √(13 · 13) = 13
3. √81 = √(9 · 9) = 9
4. √225 = √(15 · 15) = 15
5. √196 = √(14 · 14) = 14
Answer: 4, 3, 1, 5, 2
You can divide it and get 2.2
Move 6x to the right side: 2y=12-6x
Divide both sides by 2: y=6-3x
m is the slope which in this case is -3
To see a graph plug y=6-3x into the website wolfram alpha!
Hope this helps!!
