where r is the radius of the circle
The standard form of a circle is
( x - h )² + ( y - k )² = r²,
where r is the radius of the circle and (h,k) is the center of the circle.
Given data ,
Let the equation for the circle A be represented as
( x - 7 )² + ( y - 1 )² = 16
Now , the equation is of the form ( x - h )² + ( y - k )² = r²
So , the radius of the circle is 4 and the center of the circle is ( 7 , 1 )
Let the equation for the circle A be represented as
( x + 8 )² + ( y - 2 )² = 16
Now , the equation is of the form ( x - h )² + ( y - k )² = r²
So , the radius of the circle is 4 and the center of the circle is ( -8 , 2 )
So , the translation of circle A to B is given by
( 7 , 1 ) to ( -8 , 2 )
So , the x coordinate is translated by 15 units to left and the y coordinate is translated by 1 unit up
Hence , the translation is given by ( x , y ) ⟶ ( x - 15 , y + 1 )

Where do you find the solution to a system?.
There are several methods for finding the solution to a system of equations, which include:
1. Graphing: This method involves plotting the equations on a coordinate plane and finding the point(s) of intersection. This method is useful when the system has a small number of variables and the equations are in the form of y = mx + b.
2. Substitution: This method involves solving one of the equations for one variable and then substituting that expression into the other equation. This method is useful when one equation is easier to solve than the other or when one equation is a simpler form than the other.
3. Elimination: This method involves adding or subtracting the equations to eliminate one of the variables. This method is useful when the variables are in similar forms and the coefficients are easy to add or subtract.
4. Matrix method: This method involves solving the system of equations in matrix form using matrix algebra techniques such as Gaussian elimination, Gauss-Jordan elimination and Cramer's rule. This method is useful when the system of equations have a large number of variables and when you want to solve system of equations in a more efficient and less time-consuming way.

the number of nickels exceeds the number of dimes by 7. the total value of the coins is $1.55. How many coins of each type are there?
Answer:
15 nickels and 8 dimes
Step-by-step explanation:
Let N = number of nickels and D = number of dimes
N - D = 7 (the number of nickels exceeds the number of dimes by 7.)
or
N = D + 7
Total value of N nickels = 5N
Total value of D nickels = 10D
Combined total value => 5N + 10D = 155
Substitute for N in terms of D
==> 5(D + 7) + 10D = 155
5D + 35 + 10D = 155
15D + 35 = 155
15D = 155 - 35
15D = 120
D = 120/15
D = 8
N = D + 7 = 8 + 7 = 15
15 nickels and 8 dimes

What is the angle sum property of a triangle?The angle sum property of a triangle states that the sum of interior angles of a triangle is 180°.
In the given triangle, we can use the concept of triangle angle sum to find the unknown measures.
We know that the sum of the angles in a triangle is always 180 degrees.
Therefore, if we know two angles in a triangle, we can find the third angle by subtracting the sum of those angles from 180.
We are given that angle A is 50 degrees. We are also given that angles B and C are unknown. Therefore,
we can use the following equation to find the measure of angles B and C:
A + B + C = 180
50 + B + C = 180
B + C = 180 - 50
B + C = 130
So the sum of angles B and C is 130 degrees. Therefore, we can't find individual measures of angles B and C.
Alternatively, we can use the property of the angle pair which states that if two parallel lines are intersected by a transversal, the alternate interior angles are congruent.
If we know that angle A and angle B are congruent, we can find the measure of angle B as 50 degrees. As a result, angle C will be 180 - 50 - B = 130-50 = 80 degrees.
Hence, the measure of angle B is 50 degrees and angle C is 80 degrees.

Where is the vertex of the parabola y X² 2x 3?.
The vertex of the equation y = x² + 2x -3 is (-1, -4).
The term vertex in math is known as a point on a polygon where the sides or edges of the object meet or where two rays or line segments meet.
Here we have the expression y = x² + 2x -3
As we all know that the given equation of parabola is written as,
=> y = ax² + bx + c
As we all know that the vertex of the parabola is given by (h, k).
Here we have calculated the value of the x coordinate of vertex as ,
=> h = -b/2a
And the value of y coordinate of vertex k by using the formula,
=> k = y(h)
Through the given equation we have identified the value of a = 1, b = 2 and c = -3
Then the value of x coordinate is calculated as,
=> h = -2/(2 × 1)
Therefore, the value of h is -1
Then the value of y coordinate is calculated as,
=> k = y (-1)
Here we have to substitute -1 in the equation, then we get
=> k = (-1)2 + 2(-1) - 3
=> k = 1 - 5 = -4
Hence the coordinate of the vertex is (-1, -4).
