Third one I think 10,20,30,40
Answer:
y=7x-6
Step-by-step explanation:
Use point-slope equation.
y-y1=m(x-x1)
y-8=7(x-2)
y-8=7x-14
y=7x-6
8 times 4 + 1 times 7 = 39
Option D
The trip lasts for 
<em><u>Solution:</u></em>
<em><u>Mr Patel is planning to drive 325 miles</u></em>
Average speed is 65 mph
He will stop one hour for lunch and take a 15 min rest break
Let us first find the time taken


Thus he covers 325 miles in 5 hours
Also, given that, he will stop one hour for lunch and take a 15 min rest break
<em><u>Therefore, total time taken for trip is:</u></em>
Total time = 5 hours + 1 hour + 15 minutes
Total time = 6 hours 15 minutes
We know that,
1 hour = 60 minutes
Therefore,

Thus the trip lasts for 
3s-4=1-3s
+3s +3s
6s-4=1
+4 +4
6s=5
s=5/6
