The midpoint of ab is M (-6,1 ). if the coordinates of A are (-7,-3 ),what are the coordinates of B

Scrat [10]

Answer:

B(-5,5).

Step-by-step explanation:

It is given that midpoint of AB is M (-6,1).

Coordinates of A are (-7,-3 ).

We need to find the coordinates of point B.

Let coordinates of point B are (a,b).

$Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)$

Midpoint of AB is

$Midpoint=\left(\dfrac{-7+a}{2},\dfrac{-3+b}{2}\right)$

$(-6,1)=\left(\dfrac{-7+a}{2},\dfrac{-3+b}{2}\right)$

On comparing both sides, we get

$\dfrac{-7+a}{2}=-6$

$-7+a=-12$

$a=-12+7$

$a=-5$

$\dfrac{-3+b}{2}=1$

$-3+b=2$

$b=2+3$

$b=5$

Therefore, the coordinates of B are (-5,5).

<u>Answer (1):</u>

Coefficient of any term means the number multiplied in that term including sign.

$ab^2$ is same as $1ab^2$ .

Hence required coefficient is 1.

<u>Answer (2):</u>

$4(3-7)^2+102$

$=4(-4)^2+102$

$=4(16)+102$

$=64+102$

$=166$

Hence final answer is 166

<u>Answer (3):</u>

$\sqrt{\frac{49}{25}}$

$=\frac{\sqrt{49}}{\sqrt{25}}$

$=\frac{7}{5}$

Hence final answer is $\frac{7}{5}$
