Answer:
6. step 2; terms are improperly combined; it should be -61n-8=-8
7. no; point (2, 5) is not part of the solution in the left graph
Step-by-step explanation:
6. Step 2 should be ...
-61n -8 = -8 . . . . . because -5n-56n = -61n, not -51n

7. The boundary lines of both graphs go through the point (2, 5). In the left graph, the line is dashed, indicating that points on the line are not part of the solution set. The point (2, 5) on the dashed line is not a solution to that inequality.
The solid boundary line indicates that the points on the line are part of the solution set. The point (2, 5) on the solid line is a solution to that inequality.
The point (2, 5) is not a solution to both inequalities.

Step-by-step explanation:
These are just ratios. They are both essentially doubling
Answer:
Step-by-step explanation:
Area of circle:
By using the area of a circle, we can get the area of a semicircle:
Let's convert the mixed fraction to an improper fraction and then a decimal:
= 
= 
Now, we solved for the diameter, to get the radius, we need to divide the diameter by 2:
Now we have the radius, so we can plug in our values and find the area:
