10x^2-23x+13
(10x-13)(X-1). Answer
Look at steps to learn this try not to just copy answer
10x(X-1)= 10x^2-10x
-13(X-1)= -13x+13
-10x^2-10x-13x+13
-10x^2-23x+13

First, we define the variables:
x: number of years after 1950
f (x): amount of vinyl sold.
Then, with the variables defined, we have:
68594 vinyl records were sold in 1958 ---------> f (8) = 68594
91299 vinyl records were sold in 1961 ---------> f (11) = 91299
38720 vinyl records were sold in 1952 ---------> f (2) = 38720
161743 vinyl records were sold in 1967 ---------> f (17) = 161743
5x+130=8x+151
subtract 5x from each side
5x-5x+130=8x-5x+151
130 = 3x+151
subtract 151 from each side
130-151 =3x
-21 = 3x
divide by 3
-21/3 = 3x/3
-7 =x
