During a chemistry experiment, Sam records how the temperature changes over time using ordered pairs, (0, 15), (5, 20), (10, 50), (15, 80), (20, 100), (25, 100) Is the relation a function? Explain.

9514 1404 393

  yes

Step-by-step explanation:

No domain value is repeated in Sam's ordered pairs, so the relation is a function.

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

the answer would be c:   ax + b = ax + c
