This should be a (2 and 3 only) because the graph never hits the x-axis so this rules 1 out. All of the other options have 1 in them so they are all incorrect. To check this we know the middle of the graph is x=2 making 3 true. 2 would be true because this is the point where the parabola hits the y axis.
Answer:
Number of Model A press = 9 and Number of Model B press = 5
Step-by-step explanation:
Number of books Model A can print per day = 70
Number of books Model B can print per day = 55
Let x be the number of Model A press and y be that of Model B press.
Total number of printing presses = 14
x + y = 14 ----------------1
Total number of books printed per day = 905
70x + 55y = 905-------2
Putting y = 14 - x in equation 2, we get:
70x + 55(14 - x) = 905
15x = 135
x = 9
y = 14 - 9 = 5
Hence number of Model A press is 9 and that of Model B press is 5.
