Answer:

<h2>v=(13,-3)</h2>

solution,

- 2 =  \frac{x - 17}{2}  \:  \\  - 2 \times 2 = x - 17 \\  - 4 = x - 17 \\  - x =  - 17 + 4 \\  - x =  - 13 \\ x = 13 \\  \\ 7 =  \frac{y + 17}{2}  \\ 14 = y + 17 \\  - y = 17 - 14 \\  - y = 3 \\ y =  - 3

Therefore,

V=(13,-3)

Hope this helps...

Good luck on your assignment..

alexandr402 [8]

Answer:

3.5 miles

Step-by-step explanation:

Lydia:

3 gallons of gas = 114 miles

We want to know how many miles a friend can travel on one gallon of gas, so we divide both sides by 3

1 gallon of gas = 114/3 miles = 38 miles

Lucy:

One point is

10x corresponds to 415y

10 gallons = 415 miles

divide both sides by 10 to get one gallon on a side

1 gallon = 41.5 miles

Lydia:

38 miles = 1 gallon

Lucy:

41.5 miles = 1 gallon

For 1 gallon, the difference is 3.5 miles, with Lydia having 3.5 miles less than Lucy.
