Answer:
The temperature in °F after x hours will be given by, y = - 8 + 2x.
Step-by-step explanation:
The temperature in the morning was - 8°F. Now, as the day went on the temperature rose 2°F each hour.
So, after x hours the temperature will rise by 2x°F.
Therefore, the temperature in °F after x hours will be given by, y = - 8 + 2x. (Answer)
Answer:
B
Step-by-step explanation:
Given
(4x² - 3x - 4) - (3x² + 4x - 8) ← distribute by - 1
= 4x² - 3x - 4 - 3x² - 4x + 8 ← collect like terms
= x² - 7x + 4 → B
Answer:
FV= $4,725.74
Step-by-step explanation:
Giving the following information:
Initial investment (PV)= $2,000
Number of periods (n)= 15 years
Interest rate (i)= 5.9% = 0.059
<u>To calculate the Future Value, we need to use the following formula:</u>
<u></u>
FV= PV*(1 + i)^n
FV= 2,000*(1.059^15)
FV= $4,725.74
