12.The graph below shows the air temperature over a 10-hour period from noon until 10:00pm
A graph is shown.
• The horizontal axis is labeled 'Time' and extends from noon to 10 p m in 2 hour increments.
• The vertical axis is labeled 'Temperature' and extends from 0 to 70 in increments of 5.
• The graph begins with a temperature of 60 at noon. This temperature gradually declines to about 50 at 2 p m, and about 40 at 6 p m.
• A slight increase is noted as the temperature is approximately 42 at 8 p m.
• The temperature then declines more rapidly to around 20 at 10 p m.

20-21 do by urself :)
i hate Conexus it's to much work and it over whelms me i might honestly go to a public school because conexus sucks ngl
@Anonymous Stop being so inmature, and no nobody is going to shut up. And nobody is dieing. Why are people like you so ignorant? Welp have a wonderful day guys I don't know the answer because I have a totally different test and my mental state is going to make me fail but I hope you all succeed! <3 search my user name on Roblox :D
hey - kinda a long shot but I've got the answers for 1-18
I think I have a few wrong, 2 or so - so don't hate for not getting a FULL 100% - because these aren't the answers for you!
I also realise the questions often change - so if that happens to you - yOu took the risk! Don't blame others for it - because we aren't secretly trying to make you fail your test!

Wait, what if someone posted what the answer actually said instead of just the letters?
please let us know because my grade is down and need a 100%
I made an 8/19 with the answers given by others here. was going to provide all the answers, though i accidentally closed out of the tab, so i only got the first few. Sorry.
1: Start with 8 and add -9 repeatedly.
2: -64, -128, -256
3: 0
4: Geometric, decreases by factor of 1/16
5: m=13, n=0
