M(6,5) is the mid-point of the straight line joining A(2 , 3) to the
charle [14.2K]

Given :

M(6,5) is the mid-point of the straight line joining A(2 , 3) to the

point B.

To Find :

The coordinates of B.

Solution :

Let, coordinates of point B is ( h , k ) .

It is given that M is the mid - point of the straight line joining points A and B.

Coordinates of M is given by :

M = (\dfrac{2+h}{2},\dfrac{3+k}{2})\\\\(6,5 ) = (\dfrac{2+h}{2},\dfrac{3+k}{2})\\\\\dfrac{2+h}{2} = 6 \ , \  \dfrac{3+k}{2} = 5\\\\h = 10 \ ,\ k = 7

Therefore, coordinates of point B is ( 10 , 7 ).

-1/2=3/2k+3/2<br> explain how you got your answer
meriva

-1/2=3/2k+3/2


Rewrite the equation to have k on left side


3/2k+3/2=-1/2


Simplify 3/2k


3k/2+3/2=12


Move all terms not containing k to right side


3k/2=1/2-3/2


3k/2=-2


Multiply both sifmdes by 2


2(3k/2)=-2(2)


3k=-4


Divide both sides by 3 to get k alone


3k/3=-4/3


K= -4/3

Which of the following points lies in the solution set of the inequality y &gt; 3x +10?
shepuryov [24]

Since 3 is greater than -3, hence (-1, 3) lie in the solution set. Option C is correct

In order to determine the points that lie in the solution set of the inequality y > 3x +10, we will substitute the x-coordinate and see if <u>y is greater than the result.</u>

<u />

For the coordinate point (1, 10)

y > 3(1) +10

y > 13

Since 10 is not greater than 13, hence (1,10) does not lie in the solution set.

For the coordinate point (4, 20)

y > 3(4) +10

y > 22

Since 20 is not greater than 22, hence (4,20) does not lie in the solution set.

For the coordinate point (-1, 3)

y > 3(-1) +10

y > -7

Since 3 is greater than -3, hence (-1, 3) lie in the solution set.
