Answer:
y=2x^2-8x+6
Step-by-step explanation:
Answer:
6
Step-by-step explanation:
Multiply both sides of the equation by 2
3x-4=14
Add 4
3x=18
Divide by 3
x=6
Good luck! Let me know if you need more help.
63,360 is how many inches are in a mile
Y = 12.1% x 13 + 351
y= 0.012 x 13 + 351
y= 1.573 + 351
y= 352.573 or $352.6
Let the distance be x miles
Time = Distance / speed
Time taken by Mike to go to his friend's house = x / 40 hours
Time taken by him to return = x / 45 hours
Total time = x / 40 + x / 45 = 4 hours
= 9x + 8x = 1440 miles
17x = 1440
= x = 1440 ÷ 7
= x = 84.706
Time taken to return home = 84.706 /45= 1.882 hours .
Therefore , Mike took 1.882 hours to reach home .
