2x/x will equal 2.
x/x is in a ratio of one to one
If, for instance, x is equal to 1235324...
2(1235324)/1235324)
2470648/1235324
2
Let the coordinates of the circumcentre O of the triangle DEF be (x, y). Circumcentre of a triangle is equidistant from each of the vertices.
1. Distance OD=distance OE, then:
.
2. Distance OD=distance OE, then:
.
Solve the system:
,
,
.
Then
.
Answer: the coordinates of the circumcenter for ∆DEF are x=4.5, y=-1.
Answer:
8.21
Step-by-step explanation:

Answer:
C: (1, 2.5)
Step-by-step explanation:
The point is not exactly on 2 or 3 on the y axis. So it is at 2.5. and when you read a graph you need to look at it from x to y so it should be C: (1, 2.5).
3+2 is 5.
1/7 +1/7 is 2/7.
Thus, the answer is 5 2/7.
