Answer:
<h3>The option B) is correct</h3><h3>Therefore the coordinate of B

is (6,-3)</h3>
Step-by-step explanation:
Given that the midpoint of segment AB is (4, 2). The coordinates of point A is (2, 7).
<h3>To Find the coordinates of point B:</h3>
- Let the coordinate of A be
is (2,7) respectively - Let the coordinate of B be

- And Let M(x,y) be the mid point of line segment AB is (4,2) respectively
- The mid-point formula is
<h3>

</h3>
- Now substitute the coordinates int he above formula we get

- Now equating we get

Multiply by 2 we get Multiply by 2 we get


Subtracting 2 on both
the sides Subtracting 7 on both the sides


Rewritting the above equation Rewritting the equation

<h3>Therefore the coordinate of B

is (6,-3)</h3><h3>Therefore the option B) is correct.</h3>
Answer: 4=40 ! Its a pattern
ANSWER

EXPLANATION
The quadratic equation is:

Group variable terms:

Add the square of half, the coefficient of y to both sides.


The LHS us now a perfect square trinomial:

Take square root:


The first choice is correct.
Answer: if you're asking how to write it then it would be 7:21
Step-by-step explanation:
x = -3, y = -2
Substitute the values of x and y to the equation xy = k:
k = (-3)(-2)
k = 6
