Question 11 :
the equations are :
now, let's graph the lines ~
As you can see in the attachment, The lines coincides each other, so the equations are :
- consistent and dependent

The first line is perpendicular, the second line is not perpendicular and not parallel , the third line is parallel to the above line and the forth line not parallel or perpendicular to the line.
<h3>How can the slope of the line be calculate?</h3>The slope of the line is been given as −3x+5y=−15
Then , hence the slope is
- Slope of the first line 5x + 3y = 15 after calculation is
the slope is
this means that the line is perpendicular to the given line
- Slope of the second line 3x + 5y = 15 after calculation is
This means that the line is not perpendicular and not parallel
- Slope of the Third line -3x + 5y = 15 can be calculated as
This means that the line is parallel to the above line.
- Slope of the first line 3x + 5y = 15 after calculation is
This means that the line is not parallel or perpendicular to the line

Answer:
25.1cm
Step-by-step explanation:
since circumference =d and d=2r
c=(2*4)
c=8
c=25.132741229
c=25.1cm
