The temperature at 2 am was -12 degrees. At noon the temperature had risen 16 degrees. At 4 pm the temp dropped 8 degrees. What was the temperature at 4 pm

- 4

because The temperature at 2 am was -12 degrees and At noon the temperature had risen 16 degrees

=> the temperature at noon was -12 + 16 = 4 (degrees)

At 4 pm the temp dropped 8 degrees => the temperature at 4 pm was:

4 - 8 = -4 (degrees)

Step-by-step explanation:

irrational, cannot

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)
