Answer:
This construction shows how to draw the perpendicular bisector of a given line segment with compass and straightedge or ruler. This both bisects the segment (divides it into two equal parts, and is perpendicular to it. It finds the midpoint of the given line segment.
Answer:
Slope: 1/4
y-intercept: -6
Step-by-step explanation:
4
I hope you have an awesome day
-4x-8>-20
+8 +8
-4x>-12
Divide by 4 on both sides
x<3
Should be A.
Hope this helps.
Answer:
1. {5,-9}
2.{4}
3.{9/2}
Step-by-step explanation:
The equation 
can be solved as follows:
Then, the solutions of the equation are 
.
Now, if 
, we can solve the equation 
as follows:
So, the unique solution of this last equation is 
The last equation is 
, where 
. To solve this equation we can proceed as follows:
But, x=11/4 is not a solution of this equation. So the unique solution is x=9/2.
