Answer:
29.42
Step-by-step explanation:
Add the total time of the songs together. to get 29.22
Then there are 4 breaks between songs so multiply 4×.05
Then those numbers together
12x^2+x-8 - (4x^2-1)
12x^2+x-8-4x^2+1
8x^2 + x - 7 =0
8x^2 + 8x - 7x -7 = 0
8x ( x + 1 ) - 7 ( x + 1 ) = 0
(8x - 7) (x + 1) =0
8x -7 = 0
x + 1 = 0
x = 7/8 and x = -1
we need to get y alone so subtract 2x from both sides of the equation
2x+4y=12
-2x -2x
-----------------------
4y=-2x+12 now divide both sides by 4
y = -2x/4 +12/4
y = -1/2 x +3
