Im having a hard !
in a local city, the temperature at noon is -3 degrees celsius. the temperature is expected to decrease 2.5 degrees celsius by each hour until the temperature reaches -18 degrees celsius.
how many hours will it take for the temperature to reach ?
a. 6 hours
b. 7 hours
c. 7.2 hours
d. 8.4 hours

Option 'A' is correct.

Step-by-step explanation:

Since we have given that

At noon, the temperature was = -3 degrees

Temperature reduced by = 2.5 hours per day

Temperature reaches = -18 degrees

Let the number of hours be 'x'.

According to question,

Hence, it will take 6 hours for the temperature to reach.

Option 'A' is correct.

this shows a reflection over the x-axis and is translated one unit down and 6 units to the right (x + 6, y - 1)

hope this !
