Considering the described changes, the temperature at 6 pm was of -14.5ºF.
<h3>How to find the temperature at 6 pm?</h3>
We look at the temperature for each interval, as follows:
- At 9 am, the temperature was -8.4°F.
- Between 9am and noon, the temperature increased by 2.6°F, hence, at noon, the temperature was of -8.4ºF + 2.6ºF = -5.8ºF.
- Between noon and 3pm, the temperature rose 1.2°F, hence, at 3 pm, the temperature was of -5.8ºF + 1.2ºF = -4.6ºF.
Between 3pm and 6pm, the temperature went down 9.9°F, hence at 6 pm, the temperature was given as follows:
-4.6ºF - 9.9ºF = -14.5ºF.
The temperature at 6 pm was of -14.5ºF.

Answer:
Hi so you have the answer
Say you have 1.23 if the last digit is under 5 it would be 1.20
Now say you have 3.47 if the last digit is above 5 it would be 3.50
If it is something like 4.45 the 5 is the last digit so it would be 4.50

Answer:
(x - 4)(x + 3)
Step-by-step explanation:
Given
x² - x - 12
Consider the factors of the constant term (- 12) which sum to give the coefficient of the x- term (- 1)
The factors are - 4 and + 3, since
- 4 × + 3 = - 12 and - 4 + 3 = - 1, then
x² - x - 12 = (x - 4)(x + 3) ← in factored form
