A cup of coffee has coded from 92°C to 50°C Cefter 12 min in a room at 22°C. How long will the cup take
to cool to 30°C

According to my calculations the cup had dropped 42°C in 12 minutes so that is equivalent to 3.5°C each minute if im not mistaken the cup is now at 22°C and needs to be warmed back up to 30°C that is a little odd but i multiplied 3.5 and the amount on minutes 22 is from 30 to get 8 so this would take a weeping 28 minutes.

kinda confusing cause the degrees is off

idk but i found this "the graph of y = f(x-2) is the graph of y = f(x) translated two units rightward.  

so, since the point (9,2) lies on the graph of y = f(x), the point (11,2) lies on the graph of y = f(x-2)."
