Answer:
(2, -8)
Step-by-step explanation:
Hi,
Work:

To find the cost of gallons spend for 310 miles you need to first find the amount of gallons consumed on 310 miles path.

If each costs 3.5$ you need to multiply gallons with money.

You would spend 38.745$ to drive 310 miles.
Hope this helps.

Answer:
x=6
Step-by-step explanation:
4x+5=6x-7
4x-6x=-7-5
-2x=-12
x=-12/-2
x=6
Answer:
mid point of AB (0.5 , 0)
Step-by-step explanation:
2x + 5y = 1 2x = 1 - 5y
y = 2xy+ 5 = (1 - 5y)*y + 5 = y - 5y² + 5
y-y = y - 5y² + 5 - y = - 5y² + 5
0 = - 5y² + 5
5y² = 5
y² = 1
y = 1 or y = -1
if y = 1 x = 1/2 (1 - 5) = -2 .... point A (-2 , 1)
if y = -1 x = 1/2 (1 + 5) = 3 ..... point B (3 , -1)
mid point of AB (x' , y') : x' = 1/2 (x₁ + x₂) = 1/2 (-2 + 3) = 1/2
y' = 1/2 (y₁ + y₂) = 1/2 (-1 + 1) = 0
(6;2)
6 - x coordinate, 2 - y coordinate.
6 > 0, then we need to move right 6 points. 2 > 0, than we need to move up 2 points
Answer: Start at the origin. Move 6 units to the right, then move 2 units up.
