Answer:
20 divided by 10 is 2 so for every 2 miles it travels it uses 1 gallon of gasoline. 20 + 14 is 34 so you divide 14 by 2 to get 7. then you add 10+7 to get 17. it will take 17 gallons of gasoline to go 34 miles
Step-by-step explanation:
Start at the first point which in this case is (-1,-4). then go up 3 (since thats where the next point is) and over to the right 1 (since thats where the point is lol). since the line is positive, then the answer is 3/1 or 3.
to find the sum:
2(3t-4) - (t^2 + 2) - 4t(t-1)
6t - 8 - t^2 - 2 - 4t^2 + 4
6t - 8 - 5t^2 + 2
-5t^2 + 6t - 6
by the sum of roots and product of roots formulae
ax^2 + bx + c
x + y = 
x + y = 
xy = 
xy = 
x - y =
I=10/3......is your answer
Your answer is 41.93529593 or 41.9
