Answer:
0 1 2 3 4
17 23 29 35 41
Explanation:
X represents the number of years the subscriptions is renewed and y represents the total cost in dollars.
so you are just going to replace x with the number of years the subscription is renewed and then you'll get the answer y which will be the total cost in dollars.
example:
X number of years renewed: 6 7 8
Y total cost in dollars: ? ? ?
y = 6 × X + 17
now replace x with the number of years renewed.
y=6×6+17
y=53 dollars
same goes with the other ones
y=6×7+17
y=59 dollars
If it was the other way around where you knew the cost but not the year. then you would replace the y with the cost and solve the equation.
example:
X number of years renewed: ? ? ?
Y total cost in dollars: $53 $59 $65
y= 6×X+17
53=6×X+17
-17 -17
36=6×X
÷6 ÷6
6=X
