What expressions are equivalent to 3(n+6)

y=2.42x+5.72

x and y are proportional

value of the card in 2003 was $17.82

Step-by-step explanation:

1.

b aka initial= 5.72

m=2.42

this is a linear relationship as it is increasing by the same amount every year

y=2.42x+5.72

2.

x and y are directly proportional as one increases the other increases as well

3. x=number of years since 1998

x=2003-1998=5 years

y=2.42x+5.72 --> substitute x

y=2.42(5)+5.72

y=17.82

value of the card in 2003 was $17.82
