How many thirds of a hallway are there to decorate in 5 hallways

1/3 x 5 = 15/3 or 5  Hope this Helps :)

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.
