Answer:
Step-by-step explanation:
Given
Represent the coordinates of circle A with (x,y)
<u>Translation</u>
Left = 3 units
Up = 4 units
Required
Determine the coordinates of B
When a point (x,y) is translated by h units left, the new point is: (x - h, y)
When a point (x,y) is translated by b units up, the new point is: (x, y + b)
So, when circle A is completely translated to B, the new points of B is:
In this case:
So:
Answer:
Where
And replacing we got:
And solving we got:
Where
And the possible solutions are:
Step-by-step explanation:
For this case we use the equation given by the image and we have:
We can rewrite the last expression like this if we multiply both sides of the equation by -1.
Now we can use the quadratic formula given by:
Where
And replacing we got:
And solving we got:
Where
And the possible solutions are:
