6:18 students in Debra's class own a cellphone. Because there are 24 people in total. Minus the people who already own cellphones. Leaving 18 without cellphones. The ratio is people who have cellphones to people who do not.
24-6=18. Thus, the ratio would be 6:18
Now, as you can see - these are ordered pairs. So, in order to find possible solutions - we have to plot this inequality on a graph!
So, let's do this. I am using GeoGebra in order to graph this inequality.
Alright, so... Now I'm going to go through, and look at each ordered pair and see if they are covered by the shaded region!
Answer A: False
Answer B: False
Answer C: True
Answer D: True
Answer E: True
Answer F: True
Hopefully, this helps you! =)
Answer:
2nd one : y = -4/x
3rd one : y + x/2 = 9
4th one
5th one : y = x^2
6th : 5.8x - y = 2.3
