Step-by-step explanation:
Slope of line is given by the formula:

Line 1:
The change in
coordinate is zero.
Therefore slope of line 1 is
.
Line 2:
Change in
coordinate = -4
Change in
coordinate = 3
Slope = 
Line 3:
Change in
coordinate = 4
Change in
coordinate = 3
Slope = 
Line 4:
The change in
coordinate is zero.
Therefore slope of line 4 is
.
Line 5:
Change in
coordinate = 7
Change in
coordinate = 3
Slope = 
Line 6:
Change in
coordinate = -7
Change in
coordinate = 3
Slope = 
Line 7:
Change in
coordinate = 0
Slope = 0
Line 8:
Change in
coordinate = 0
Slope = 0
Line 9:
The change in
coordinate is zero.
Therefore slope of line 9 is
.
Line 10:
The change in
coordinate is zero.
Therefore slope of line 10 is
.
Line 11:
The change in
coordinate is zero.
Therefore slope of line 11 is 0.
Line 12:
The change in
coordinate is zero.
Therefore slope of line 12 is
.
115.20 is 20% of 576
576 x .20 = 115.20
Answer:
x=m-a/12
the m-a should be over 12 as the numerator but it's hard to type it like that
Step-by-step explanation:
a+12x=m
12x=m-a
x=m-a/12
Answer:
52
Step-by-step explanation:
That is dependent because it is changing.independent stays the same
