Answer:
Movie: $4.25
Video Game: $5.25
Step-by-step explanation:
For this problem, we can use system of equations to solve for the rental costs of the movies and video games. Let's use x for movies and y for video games.
Equation 1
5x+3y=37
Equation 2
2x+6y=40
To start, we can use elimination to solve for x and y. Let's cancel out y. To do so, we have to multiply the first equation by 2 to get the y equal.
10x+6y=74
Now that the y are equal, we can subtract both equations.
8x=34
x=4.25
The movie rental cost is $4.25.
Now that we know x, we can plug in to find y.
2(4.25)+6y=40
8.5+6y=40
6y=31.5
y=5.25
The rental cost for video games is $5.25.

- Range is the set of y-values that are outputted by function f(x).
Step-by-step explanation:
According to the graph, we have a horizontal asymptote at y = 5. Therefore, the graph never actually <em>touches/reaches</em> the y-value 5. Therefore, 5 is not included in our range:
(5, ∞) or y ≥ 5
