Option 1 is correct. The point T is the number of books and their cost where the subscription with the annual fee costs less.
<h3>How to find the point T.</h3>
At y1 = 96
y2 = 30
The service charge is said to be 3 dollar
We have that y1 is less than y2. This is because 30 is less than 92.
From this we have to conclude that it is the first option. This is because 3 dollars would be charged or less than that.
<h3>Complete question</h3>
Aaden wants to get a subscription to an online library. There are two subscription options, one of which charges a fixed dollar annual fee and the other which charges dollars per book he borrows. Here's a graph that shows a system of equations for this scenario where is the number of books Aaden borrows and y is the total cost of the subscription. ks) What does point T represent in this ? Choose 1 answer:
A number of books and their cost where the subscription with the annual fee costs less
A number of books and their cost where the subscription that charges per book costs less of

Answer: The length of the candle was 13.5 inches before it was lit.
Step-by-step explanation:
Let the length of candle in the beginning be c.
Constant rate of change in length of candle= -1.6 inches per hour
Since rate of change is constant so the length of candle can be represented by a linear function [Linear function has constant rate of change.]
Linear function : f(x)= mx+c , where x= independent variable.
m= constant rate of change and c= initial value of function.
Let x = Number of hours after the candle was lit.
Put m= -1.6 , x= 3 and f(x)= 8.7 , we get
Hence, the length of the candle was 13.5 inches before it was lit.
