Athermometer reading 7 °c is brought into a room with a constant temperature of 34°c. if the thermometer reads 14 °c after 4 minutes, what will it read after being in the room for 6 minutes? for 11 minutes?

For this case we are going to define the following variable:
 x: time in minutes
 We write the linear function that represents the problem:
 t (x) = (14/4) x + 7
 For x = 6 we have:
 t (6) = (14/4) * (6) + 7
 t (6) = 28 ° C
 For x = 11 we have:
 t (11) = (14/4) * (11) + 7
 t (11) = 45.5 ° C
 
 t (6) = 28 ° C
 t (11) = 45.5 ° C

Something that is true about that is that it has numbers

Ithink it’s b, hope this .
