X=3, y=4
x=-2, y=9
Set x equal to anything, then isolate y to get the other number.
Part A
The first thing we must do in this case is to hide the slopes of each line.
line m:
m = (- 4-3) / (0 - (- 4))
m = -7 / 4
Line n:
n = (- 2-2) / (3-1)
n = -4 / 2
n = -2
Answer:
Lines m and n are not parallel because their slopes are different.
Part B:
We look for the slope of the K line:
k = (1 - (- 3)) / (4 - (- 3))
k = 4/7
We observe that it is true that:
k = -1 / m
Answer:
The lines are perpendicular.
The Formula would be A=3.14rr
Which is A=3.14(3)(3)
The answer is 28.26
It is my opinion that it is C) but i am not sure, you might be correct though...
Answer:
%28.57 (14285714286)
Step-by-step explanation:
Divid To get decimal (percent right)
250/350= 0.714285714285714
Subtract from 1 to get decimal (Percent wrong)
1.0 - 0.714285714285714= 0.285714285714286
Move over decimal to placements to the right to convert to percent
%28.5714285714286
Round
%28.57
