Answer:
The number decays each year
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
-(9x+12)=-8x-(x+3)
-9x-12= -8x-x-3
-9x+9x=9
-9
if u look at the eq for x it has no value. but if u r asking a solution for a eq then it is -9
<h2><u>The solution set to inequality is:</u></h2>

<em><u>Solution:</u></em>
<em><u>Given inequality is:</u></em>

We have to find the solution set to inequality
From given,

Expand


<em><u>Thus the solution set is:</u></em>
