2 20. Given linear function g(x) = 5 - 5x
3
a) find g(9)
ces.
a)
b) solve g(x)=7 for x
b)

a) g(9)= 5-5(9) = 5-45= -40

b) 5-5x=7

-5x=7-5

-5x=2

x= -(2/5)

false

step-by-step explanation:

i looked it up

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
