Hello Missjay12,
Step 1 :
From the coordinates we have to find the slopes and midpoints of the lines.
Step 2 :
Find the slope of the bisectors and now find the equations of two lines by using slope and one mid points.
Step 3 :
Solve any two pair of equations and find the intersection point.
Step 4 :
The point thus found is the circumcenter of the given triangle.
so<span> the coordinates of the circumcenter of a triangle with vertices A(−3, 3) , B(−1, 3) , and C(−1, −1)</span> is, -4, 0.
There are 1000 grams in a kg, so 6300x1000=6,300,000 grams
A 15% percent markup means that the typewriter cost was increased by 15%, or 0.15 by moving the decimal 2 places to the left. If the original price was x, and 15% of it is 0.15*x, we can add them up to get 1.15*x=129.95. Dividing both sides by 1.15, we get x=113 dollars
