Okay, first you need to know the distance...since the x coordinate does not change we can see that the distance between the two points is just y2-y1, in this case:
3--6=9 so the houses are 9 miles apart.
distance=velocity times time...
d=vt so we can say
t=d/v, we found d=9 and we are told that v=12mph so
t=9mi(h/12mi)
t=0.75 hr, but the question want the time in minutes so
0.75hr(60min/hr)=45 min
So it takes Curtis 45 minute to reach his friends house 9 miles away riding at 12 miles per hour.
Answer:
No unless x is being used to define only elements of an integer set.
Step-by-step explanation:
No, not in general unless x is defined as a integer or a subset of the integers like the naturals, whole numbers....
Usually 6<=x<=10 means all real numbers between 6 and 10, inclusive. This means example that 6.6 or 2pi are in this set with infinitely other numbers that I can't name.
{6,7,8,9,10} just means the set containing the numbers 6,7,8,9,10 and that's only those 5 numbers.
