Answer:
x)x+5x
Step-by-step explanation:
No it’s not a rational number
A) We know that

where d

= distance,
v = velocity,
t = time
In this case, d = 2 mi., t = 30 min. So we get

Dividing both sides by 30, we get

Thus a function for his walk would be

where y = distance and x = number of minutes he walks.
b) Domain of a function is a set of x-values on which the function defined. In this case, the number of minutes is 30 at maximum. So the domain of the function is [0, 30].
