Find the coordinates of the other endpoint of the segment, given its midpoint and one endpoint. (Hint: Let (x, y) be the unknown endpoint. Apply the midpoint formula, and solve the two equations for x and y.)
midpoint (-8,- 4), endpoint (-11, - 11)

Solve for x by completing the square. 2x^2-4x+7=0

3. solve by graphing: y = 2x + 6 x + y = -3

Two fire-lookout stations are 190 miles apart, with station a directly south of station b. both stations spot a fire. the bearing of the fire from station a is upper n 55 degrees upper e and the bearing of the fire from station b is upper s 60 degrees e. how far, to the nearest tenth of a mile, is the fire from each lookout station?
