At union station, you notice that three subway lines just arrived at the same time. how long must you wait until all three lines arrive at union station at the same time again?

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.

50*10 is greater

step-by-step explanation:

if you add the zero from 10 to 50, it will give you a bigger number.

47 - 90 = 43

43 - 180 = x

x = 137
