The point,(-2,3) is a solution to the following system. y>-2x-2 and y< 3true or false
2 answers:
Answer: FALSE.
Step-by-step explanation:
Given the system of inequalities:
We can know if the point (-2,3) is a solution to the following system with the graph of the system of inequalities.
By definition the solution is the intersection region of all the solutions of the system of inequalities.
Knowing this and analizing the graph attached, we can notice that the point (-2,3) is not included in the intersection region (Remember that with symbols "<" and ">" the lines are dashed and any point that lines of these lines is not included in the intersection region).
Therefore, it is not a solution to the system.

Answer:
3.48 hours
Step-by-step explanation:
The equation is:
Where
M(t) is the amount of medication remaining in mg
t is the time it takes, in hours
The questions asks HOW LONG it will take to make the remaining medication to 1 milligrams (1 mg)??
We have to substitute M(t) with "1" and find the corresponding value of "t". We will use natural log to solve this. Shown below:
<u>Note: </u> Ln(e) = 1
This means, the amount of time it will take is about 3.48 hours
