We know that
if the dilated circle <span>passes through the point (4, 0)
so
the new radius is the distance from the origin to point (4,0)
d=</span>√[(4-0)²+0²]-----> d=√16------> d=4 units
the new radius is 4 units
original radius is 1 units
[new radius]=[scale]*[original radius]
scale=new radius/original radius-----> scale=4/1-----> 4
the answer is
<span>the scale factor of dilation is 4</span>
Divide the 1st equation by 2:
Divide the 2nd equation by 3:
Therefore, when we subtract the exact the 1st equation by the 2nd equation:
Substituting back into the 2nd equation will give:
For a division problem, we need to follow these rules.
3 2/3 divided by 3/4
Keep the first fraction
3 2/3
Change the sign
X
Flip the second fraction
4/3
Now multiply
3 2/3 = 11/3
11/3 * 4/3 = 44/9
44/9 >>
9*4 = 36
44-36 = 8
4 8/9
Answer: 4 8/9
