The following pairs of equations are equivalent. Determine the property that was used to write the second equation.
a. 2(x + 4) = 14 - 6x and 2x + 8 = 14 - 6x

(a) the volume of the cone is 20/3 in3

hence, option a is correct.

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
