Answer:

Step-by-step explanation:
Given
The attached graph
Required
Equations with higher unit rate
First, calculate the unit rate of the graph

Where:


So:



For the given options.
The unit rate is the coefficient of x
So: 
Going by the above definition of unit rate.




















The unit rates grater than the graph's from small to large are:


I believe the answer is 4.50
Answer:
<em>Worker B needs 9 days to finish the rest of the work</em>
Step-by-step explanation:
<u>Proportions</u>
Worker A finishes a project on his own in 12 days and worker B does the same in 16 days.
Worker A does 1/12 of the project in one day and worker B does 1/16 of the project in one day. When working together, they do

After 3 days they have completed:

parts of the project, this means it still remains:

parts of the project and it is done by B alone. Since B does
per day, he now takes

days to complete the project.
Worker B needs 9 days to finish the rest of the work
