7 0

Answer:

x = 7/2

Step-by-step explanation:

Solve for x over the real numbers:

(3 x - 2) (x + 4) - 3 (x + 5) (x - 1) = 0

Expand out terms of the left hand side:

7 - 2 x = 0

Multiply both sides by -1:

2 x - 7 = 0

Add 7 to both sides:

2 x = 7

Divide both sides by 2:

Answer: x = 7/2

x = gasoline used = 1 gallon

y = distance = d = 25 miles

That is, (1, d) represents when x = 1, y = 25.

Thus, (1, 25) is the unit rate which is 25miles per gallon.
