One car 40 miles /gallon
other car 30 miles/gallon
..
Total miles = 165
gas used = 45 gallons
...
let first car drive x miles
second car drive y miles
..
x/40 + y/30 = 45
(30x+40y)/30*40 = 45
30x+40y = 45*40*30
30x+40y=54,000

The marked points on f(x) → f(x - 2) are
(0, 0 ) → (2, 0 )
(2, 4 ) → (4, 4 )
(3, 9 ) → (5, 9 )
