Step-by-step explanation:
Given
See attachment for complete question
Required
The length difference
Lengths with dot(s) means, there is at least 1 rose flower of that length.
So, from the attachment, we have:
The difference (d) is:
This gives:
<em>Hence, Mieko is correct</em>
Given:
The system of inequalities:
To find:
Whether the points (–3,–2) and (3,2) are in the solution set of the given system of inequalities.
Solution:
A point is in the solution set of the given system of inequalities if it satisfies both inequalities.
Check for the point (-3,-2).
This statement is true.
This statement is also true.
Since the point (-3,-2) satisfies both inequalities, therefore (-3,-2) is in the solution set of the given system of inequalities.
Now, check for the point (3,2).
This statement is false because .
Since the point (3,2) does not satisfy the second inequality, therefore (3,2) is not in the solution set of the given system of inequalities.
