Answer:
These are two secant lines meaning we can use theorem 6-17 to find the value of x: 6x + 8x times 8x = 16 times 7
14x times 8x = 112
112x^2 = 112
x^2 = 1
x = 1
We need to find the lowest common multiple...
multiples of 14 are : 14,28,42,56,70,84,98,112,126,140,154
multiples of 20 are : 20,40,60,80,100,120,140
so the lowest common multiple is 140....so thats 140 minutes....= 2 hrs 20 minutes....from 8:00 = 10:20
so they will both leave at the same time of 10:20 a.m. <==
Answer: y= -5/7 x + 1/7
