102- you need to divide 2,142 by seven (for the seven dollars per ticket) then divide by 3 (for the 3 days).
Answer:
I'm not good at explaining things, but I took the test and know for a fact that the correct answer is 2. The positive difference in the y-intercept value of f(x) (1,) and g(x) (3,) is 2. 3 - 1 = 2 easy maths. Enjoy <3
X = 1 and y = 8 so (1,8) would be the correct answer

Recall your d = rt, distance = rate * time
the rate going south is 13, the rate going east is 10
it took a total amount of 6hours and 72miles for the whole travel
so.. if going say hmmm South, it covered a distance of "d", then going East it covered a distance of the slack from 72 and "d", it covered "72 - d" miles
so, if going South it took "t" hours, then going East it took the slack from 6 and "t", or "6 - t" hours
thus
![\bf \begin{array}{lccclll} &distance&rate&time\\ &-----&-----&-----\\ South&d&13&t\\ East&72-d&10&6-t \end{array} \\\\\\ \begin{cases} \boxed{d}=13t\\ 72-d=10(6-t)\\ ----------\\ 72-\boxed{13t}=10(6-t) \end{cases}](https://tex.z-dn.net/?f=%5Cbf%20%5Cbegin%7Barray%7D%7Blccclll%7D%0A%26distance%26rate%26time%5C%5C%0A%26-----%26-----%26-----%5C%5C%0ASouth%26d%2613%26t%5C%5C%0AEast%2672-d%2610%266-t%0A%5Cend%7Barray%7D%0A%5C%5C%5C%5C%5C%5C%0A%5Cbegin%7Bcases%7D%0A%5Cboxed%7Bd%7D%3D13t%5C%5C%0A72-d%3D10%286-t%29%5C%5C%0A----------%5C%5C%0A72-%5Cboxed%7B13t%7D%3D10%286-t%29%0A%5Cend%7Bcases%7D)
solve for "t"
so, it travelled East for 6-t hours
