A pair of fire towers uses technology to search for forest fires, Let the center of the forest be the origin on
a coordinate grid. The first fire tower is located 5 km
east and 8 km south of the center, and the second fire
tower is located 7 km west and 4 km north of the
center. The technology at the first tower can locate fires
within a radius of 10 km and the second tower within a
radius of 9 km. The system of inequalities represents
this scenario.
At which location, from the origin, would a fire be
detected by both towers?
O 2 km east and 3 km south
O3 km east and2 km north
O2 km west and 1 km north
O1 km west and 2 km south
