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?
-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
