Rosa saved up her money and bought a model train. Each of the 8 cars on the train was the same length. When Rosa put all the cars together, the train was 3 feet long. How long was each car? ​

4.5 inches long

Step-by-step explanation:

3 feet is equal to 36 inches, so you do 36/8 which equals out to 4.5 inches per car

step-by-step explanation:

here's what happens:

1) the graph of f   = x^2 is shifted 2 units to the right.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.

the solution is 12x-6y
