This is what I got hope it helps!
You can divide both the top by 5
10/5 = 2
15/5 = 3
Therefore 10/15 is equivalent to 2/3
Part A: After 9 days the radius of algae was approximately 12.81 mm. The reasonable domain to point is (0,9).
Part B: The 9 on the y-intercept represents the amount of algae the experiment started with.
Part C: (12.81-10.12)/7=0.38
There is no image how do you expect me to help
