Answer:
2.8 hours
Step-by-step explanation:
Distance = rate * time
If the west-bound train travels at a rate of 80 mph for t hours, then the distance it travels is 80t.
If the east-bound train travels at a rate of 90 mph for t hours, then the distance it travels is 90t.
The distance between the trains after t hours is 476; therefore, the distance of the west-bound train plus the distance of the east-bound train equals the total distance between them, 476:
80t + 90t = 476 and
170t = 476 so
t = 2.8 hours
value of x is: 
Step-by-step explanation:
We need to solve the equation f(x)=g(x)
where 
and 
Solving to find f(x)=g(x)
Putting values of f(x) and g(x)
So, value of x is:
The graph will be a straight line x= -2.58 or x = -31/12
