A) -6
B) 6
C) 42
D) -42

Answer 1

The integer representing the temperature change from 7 A.M. to 11 A.M. is -6, as the temperature dropped by 6 degrees.

Step-by-step explanation:

The student is asking about the temperature change over a certain period and what integer represents this change. Initially, it was 48 °F at 11 P.M. By 7 A.M., it had dropped by 6 degrees, so the temperature at 7 A.M. was 48 °F - 6 °F = 42 °F. Since the question is asking for the integer representing the temperature change from 7 A.M. to 11 A.M., and it's already stated that it dropped 6 degrees from the night before to 7 A.M., the integer for the temperature change during this period is -6.
