From 12:00 midnight to 6:00 am the temperature decreased by 12°. If the original temperature was 12°C which expression can be used to represent this situation? A. 12 - 12
B. 12 + 12
C. 12 - (-12)
D. -12 + (-12)

the answer is c.

for continuous functions, they continue in the same pattern and you have to find that pattern kinda like slope

the answer is d

for problems like this theres an app, its photomath that explains the problem and gives the answer hope i

all you should have to do is insert 1 where the c is, representing that one car is sold.

f(c) = 250c + 500

f(1) = 250(1) + 500

f(1) = 250 + 500

f(1) = 750

he earns $750 for each car sold.

hope this you! have a happy , here's a turkey!
