Explain how you would construct a perpendicular bisector of WX using a compass and a straightedge. (31 points guys)
Answers
Answer:
To construct perpendicular bisector of line segment WX. There are following steps:
- Construct arcs or circles from points A and B on the both endpoints of line segment WX.
- Mark the intersection points of circles as A and B.
- Use the straightedge to draw a line through points W and X.
- Mark the intersection point on WX point as O
Hence we have constructed perpendicular bisector AB of WX which bisects at O.

Hi Brainiac
y= 5x-9
y= 2x+6
We need to solve y=5x-9 for y
Let's start by substitute 5x-9 for y in y=2x+6
y=2x+6
5x-9=2x+6
Add -2x to both sides
5x-9-2x=2x+6-2x
3x-9=6
Now add 9
3x-9+9= 6+9
3x=15
Now divide both sides by 3 so we find the value for x
3x/3= 15/3
x= 5
Now we have x :)
We gonna find the value for y by substitute 5 for x in y=5x-9
y=5x-9
y= 5(5)-9
y=25-9
y= 16
Final answer : x= 5 and y=16

Step-by-step explanation:
To find the average rate of change we find
f(3) -f(0)
----------
3-0
We need to find f(3) = 1/4 (3)^2 -4 = 1/4 (9) -4 = 9/4 -4 = -7/4
f(0) = 1/4 (0)^2 - 4 = -4
f(3) -f(0)

1/4
Answer:
3/4
Step-by-step explanation:
The x values are 0 and 3. Use the formula y2-y1/x2-x1
Plug in the x factors into the orginal equation. Should look like the equations below:
f(x)=1/4(0)^2-4 -------> -4
f(x)=1/4(3)^2-4 --------> -7/4Now plug it in to the formula we saved earlier.
-7/4-(-4)/3-0= -7/4+4/3= -7/4+16/4/3
Then simplify it.
9/4/3, and in this case we have a fraction in a fraction and when this happens just multiply the equation by the x variables reciprical which in this case the x is 3 so the equation is multiplied by 1/3 and you would get 9/12. Now simplify that and you get 3/4.
