John owes 15 dollars to Bill, then another 2 dollars to Joey. How much money does John have?
Since John has 0 dollars to give, he has (-15)+(-2) =-17 dollars (as 15+2=17, so the same can be applied negatively) as the first 17 dollars he gets has to be given to Bill and Joey

It will be irrational. The sum of any irrational and rational number will ALWAYS result in a irrational answer. Khan Academy has a video on this if you want to watch it.
Answer:
1) 102.7 meters
2) 11
Step-by-step explanation:
1) -4.9x² + 75x = -4.9x² + 50x + 38
25x = 38
x = 1.52 s
Height = -4.9(1.52)² + 75(1.52) = 102.67904 m = 102.7 m
2) f(x) = x² + 3x - 2
f(2) = 2² + 3(2) - 2 = 8
f(6) = 6² + 3(6) - 2 = 52
Average rate of change:
(52-8)/(6-2) = 11
