at midnight the temp was 5 degress celcious and the temp was dropping a 2 degress celcious per hour. what would an ineaquatiilty that represents t, the number of hours past midnight, when the temp was colder than -4 degrees celsius 2?

Answer 1

-4 > 5 - 2t

Simplifying the inequality:

-4 > -2t + 5

-2t < -9

Dividing both sides by -2 and flipping the inequality:

t > 4.5

Therefore, the inequality that represents t when the temp was colder than -4 degrees Celsius is:

t > 4.5
