The graphs seem to be of two mSelecI c iines. (b) Can you conclude that the system of equations whose graphs are shown is inconsistent? Explain. Because we do not know definitively that the slopes of the two lines are the same, we "Select" 0 assume the system is inconsistent. Need Help? III-din Suhmil Answer 19. [14.54 Points] DETAILS LARPCALC11 7.2.064. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER The graphs of the two equations appear to be parallel. Yet, when you soive the system algebraically, you find that the system does have a solution. {21x , 20y = a 16x 15y = 75 Find the solution. w > Explain why it does not appear on the portion of the graph shown. O The point of intersection is negative. 0 The point of intersection is imaginary. 0 There are multiple points of intersection. C) It is necessary to change the scale on the axes to see the point of intersection. O The point of intersection does not exist. Need Help? _ Submit
