You can set up two equations from the information given. I will set them up for you:
32 = 4x + 2y
36 = 5x + 2y
Let's solve the first equation to come up with a value for y.
32 = 4x + 2y
32 - 4x = 2y
16 - 2x = y
Now we plug y into the other equation.
36 = 5x + 2(16-2x)
36 = 5x + 32 - 4x
4 = x
Now we have our real x value and we can plug it into the first equation.
32 = 4(4) + 2y
32 = 16 + 2y
16 = 2y
8 = y
Since x = 4 and y = 8, you get the final coordinates of (4,8).
Your answer is the second statement provided above.
when the song is at 1, the cost is 0.99, when the songs are at 2, the cost is $1.98
Divide the cost by the number of song: 1.98 / 2 = 0.99 per song.
The unit rate is $0.99 per song.
(x*2 + 11x)+ 24
half of 11 is 5.5*2
(x*2+ 11x + 30.25 ) + 24 -30.25
(x*2 + 11x) -6.25
so
Vertex (11,-6.25)
