D. (I used 3.14 as pi so my answer was a little off so I just went with the one closest to my answer)
First you have to figure out how much a video game costs and how much a used one costs
Then you plug in the costs of the video games into Janets equation 120=3x+y
(x= video games and y=used video games)
Then you subtract the cost of video games from 120 and then divide that answer by the cost of used video games and that should give you how many used video games she can get
The bottom left is the function.
Assuming you meant 45x^2y^2+18*3 , it should be 9(5x^2y^2+6)
Answer:
y < x
y < 4
Step-by-step explanation:
Dotted line means < or >, and since the shaded region is below the lines y = 4 and y = x, the answer is A.
