It is given in the question that
Ben has a collection of 812 stamps. He gives his brother 345 stamps.
And we have to find how many stamps does Ben have left .
Let x stamps are left.
So we have
Subtracting 345 from both sides
Therefore after giving 345 stamps to his brother, 467 stamps are left .
Answer:
The center is (-3,2) and the radius is r=2
Step-by-step explanation:
The general equation of the given circle is
Add the square of half the coefficient of the linear terms to both sides of the equation to obtain;
The quadratic trinomials in x and y on the left side of the equations are perfect squares.
We factor to obtain;
Comparing to:
The center is (-3,2) and the radius is r=2
