H(x) = 2.63x - 15.78
What is the value of x if h(x) = 13.15?

5

Step-by-step explanation:

2.63x5 = 15.78

h(x) = 2.63x - 15.78

Given the value of h(x),

13.15 = 2.63x - 15.78

2.63x = 13.15 + 15.78

2.63x = 28.93

x = 28.93/2.63

x = 11.

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
