No is your answer

Assuming that b ≠ a, the answers will not be the same.

For example, (remembering that b ≠ a) let us assume that b = 10, a = 5

10 - 5 = 5

5 - 10 = -5

5 ≠ -5

So the commutative property of subtraction does not work unless in certain cases, in which a = b.

hope this helps

Answer:

The ship will be $37.5\ km$ far from its port 3.5 hours from now

Step-by-step explanation:

The function is $y=5x +20$ relates the number of kilometers y the ship will be from its port x hours from now, it has a form $y=vt+y_{0} \ where \ y\ is\ final\ distance\\v\ is\ velocity\ in\ km/h,\ t\ is\ time\\and\ y_{0}\ is\ initial\ distance$ .

As the function is clearly defined, we only have to evaluate it for $x=3.5$ , so $y(3.5)=5(3.5)+20=17.5+20=37.5 \ km$ is the distance between the cruise ship and its port after 3.5 hours.
