Answer:
y=120-4x
Step-by-step explanation:
Here we are given the average speed for Day 1 and Day 2 and the time of ride . We asked to Find an expression to determine the total distance travelled in two days.
Day 1 :
Avg Speed = 8 mph
Let the time for travelling = x hrs
Hence Distace Travelled D1= Speed x Time
D1=8x
Day 2 :
Avg Speed = 12 mph
Total time of travelling for two days is given as 10 hours . Hence the time of travelling for day 2 is
= (10-x) hrs
Hence Distance travelled in Day 2 D2 = speed x time
D2 = 12(10-x)
D2=120-12x
Total Distance travelled = D1 + D2
= 8x+120-12x
=120-4x
If the total distance travelled is denoted by y
The expression will be
y=120-4x
If two events are independent, then
.
Use formulas for conditional probabilities:
.
For independent events these formulas will be:
.
Now in your case 
and 
.
This shows that the only correct choice is A.

Answer:
$147,848.5
Step-by-step explanation:
Fixed rate =7.35%
Mortgage Loan= $685,000
Selling price=$782,000
Property tax paid= $14,578.15
Therefore,
Prorated Amount Owed= Outstanding balance on the house + Interest paid on the loan for the year
Prorated Amount Owed=(782500-685000)+7.35% of 685000
=97500+50347.5
=$147,847.5
