Therefore, complex solutions cannot be found by graphing the related system or function in the Cartesian (x-y) plane. Polynomial functions with all complex solutions do not have x-intercepts, and the related system of equations will not intersect.
The correct answer for the question that is being presented above is this one: "<span>C. 600 mi./hr. "</span>
Plane flies from City A to City B in 12 minutes. The distance is 120 miles. 12 minutes is just 0.2 of 60 minutes. = 120 miles / 0.2 hour = 600 miles / hour
