Question

Math help please!!

Answer 1

show me what you have so far

Answer 2

Look at the graph for car 1. Where does it cross the x axis?

Answer 3

the point (70,0)

Answer 4

what this means is that when x = 70, y = 0

x = time
y = distance

when the time is 70 minutes, the distance is 0 (ie you get to the destination)

Answer 5

that's what the x intercept means for car 1

Answer 6

notice in the table for car 1 how x = 70 and y = 0 pair up (first two rows, last column)

Answer 7

look at the graph of car 2. Where does the curve cross the y axis?

you can also look at the table for car 2 and look for the y value when x = 0

Answer 8

yes so this is basically saying that at the beginning time (time t=0 minutes), the distance away from home is 70 km

Answer 9

the distance car 2 is away from the destination is 70 km

Answer 10

give it a shot and tell me what you think

Answer 11

x is involved somehow

Answer 12

I think you meant to say \[\Large 0 \le x \le 70\] ???

Answer 13

Answer 14

what about the equation?

Answer 15

the domain of car 1 is
