Answer:
y = 3x -4
Step-by-step explanation:
The slope-intercept equation looks like this: . Where m is the slope of the function and b is the y-coordinate of the vertical intercept (where the function crosses the y-axis). Let's apply the formula:
27000
1) 45 minutes
2) they meet in 20 minutes
3) (12-6)/(20/60)=18kmh
This is the correct answer. x > 4
