Hi.
First, let's calculate how many miles he has left.
80 - 14 = 66
Now, to figure out how many miles a day in 6 days, divide.
66/6 = 11
Xavier should bike 11 miles on each of the 6 remaining days.
It's a cubic with a positive x^3 coefficient. The general shape is "/".
It goes to -∞ for large negative x.
It goes to +∞ for large positive x.
In order to answer, I would first need to know Jana's speed, not that she biked at a constant rate.
Answer: b
Step-by-step explanation: 19 x 3 = 57 & 12 x 3= 36 so subtract 57 and 36 that’s going to give you 21 & 21 plus 6 is 27
