The procedure to solve a polynomial or rational inequality may be applied to all inequalities of the f ( x ) > 0 , f ( x ) < 0 , f ( x ) ≥ 0 and f ( x ) ≤ 0 . That is, find the real solutions to the related equation and determine restricted values of x . Then determine the sign of f ( x ) on each interval defined by the boundary points. Use this process to solve the inequalities in Exercises 109–120 4 − x − 6 ≥ 0

InThe Northern Lights are bright flashes of colored light between 50 and 200 miles above Earth.
Suppose a flash occurs 150 miles above Earth. What is the measure of arc BD, the portion of Earth
from which the flash is visible? (Earth’s radius is approximately 4000 miles.)
