Help with these twoo

g(N)=3 + 7n

80 = 3 + 7n

move the variable to the left hand side so

80 - 7n = 3

now do 3 - 80 to get -7n = -77

now divide both sides by -7 to get

n=11

2nd

p(x) = 4x

6= 4x

so swap the equations so its

4x = 6

next divide both sides by 4

x = 3/2 or 1.5

Step-by-step explanation:

$20.01

step-by-step explanation:

the sale price is (1.00 - 0.77)($87), or 0.23($87), or $20.01.

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
