Answer:
the radius is half of O
Step-by-step explanation:
The triangle inequality applies.
In order for ACD to be a triangle, the length of AC must lie between CD-DA=0 and CD+DA=8.
In order for ABD to be a triangle, the length of AC must lie between BC-AB=3 and BC+AB=9.
The values common to both these restrictions are numbers between 3 and 8. Assuming we don't want the diagonal to be coincident with any sides, its integer length will be one of ...
{4, 5, 6, 7}
Answer:
-3 constant , x variable +7 constant
126 = 63 x 2 = 21 x 3 x 2 = 7 x 3 x 3 x 2
=> 126 = 2 x 3² x 7
This is easy because they y's will cancel out. I love this method it's the easiest one out of substitution, and graphing.
So the Y's will cancel out an you will get x=2. Then you plug the 2 in for x in the first equation. so it will 2+y-3. You subtract 2 from both sides to get y=1.
So the ordered pair is(2,1) :)
