[Done] A treasure map says that a treasure is buried so that it partitions the distance between a rock and a tree in a 5:9 ratio. Marina traced the map onto a coordinate plane to find the exact location of the treasure. [tex]x=\left(\frac{m}{m+n}\right)\left(x_2-x_1\right)+x_1[/tex] [tex]v=\left(\frac{m}{m+n}\right)\left(v_2-v_1\right)+v_1[/tex] What are the coordinates of the treasure? If necessary, round the coordinates to the nearest tenth. A. (11.4, 14.2) B. (7.6, 8.8) C. (5.7, 7.5) D. (10.2, 12.6)
