Nope! Never heard of him! Is he REALLY IMPORTANT, OR IS IT JUST ME???

find the coordinates of the midpoint of HX. H(-1,3), X(7,-1)

$$\vec{H}=\left(\begin{array}{rcl}
-1\\3
\end{array}
\right)
\quad
\vec{X}=\left(\begin{array}{rcl}
7\\-1
\end{array}
\right)
\quad
\vec{midpoint}=\dfrac{\vec{H}+\vec{X}} {2}$$

$$\\\vec{midpoint}=\dfrac{
\left(\begin{array}{rcl}
-1\\3
\end{array}
\right)
+
\left(\begin{array}{rcl}
7\\-1
\end{array}
\right)
}
{2}
=
\dfrac{
\left(\begin{array}{rcl}
-1+7\\3-1
\end{array}
\right)
}
{2}
=
\dfrac{
\left(\begin{array}{rcl}
6\\2\end{array}
\right)
}
{2}
=
\left(\begin{array}{rcl}
3\\1\end{array}
\right)$$

his name is Narendra Modi , dont u know about him .................weird!

I meant who it is, or what it is...

what do you mean how he is?

To find the midpoint   .... add the x coordinates and divide by 2   ...then, add the y coordinates and divide by 2.......the first result will be the x coordinate of the midpoint and the second result will give you the y coordinate of the midpoint....

How is India's PM.?

Aww thank you so much!your really sweet Dragon!i'll give u some points!

btw do you guys know that today along with my birthday , its India's PM's birthday aswell!wow!

I do know one thing you like, no here it is!

oh thank you CPhill for telling me i'll give u a point for that!

The 'big bang' is merely a conjecture, a working theory, it's unproven.  Astrophysicists could come up with a new, different, theory sometime in the future.

thats really sweet DragonSlayer , thank you very much! 

Happy birthday to you, happy birthday to you, happy birthday to rosala, happy birthday to you!

CPhill what is big bang?

so we shall do this like

8u=3u+35           (so we will bring like values on one side)

8u-3u=35             (and now simply subtract)

5u = 35                             ( now we will birng 5 to the other side and then divide by 35 which then gives us u)

u = 35/5             (now simply divide)

u = 7   ANSWER

i hope u've understood by now but if not then pls be free to ask!

hope it helps!

so that totals to

35+100=135  

but u tols how many pens in total u bought so in the question youve said that u bought 100 more pens but u HAD 35 already so u bought 100 pens in total!

yes Cphill's right anonymous!u cant just spill water on ones imagination or something else!

oh yeah so that totals to 14 , my age!and thanks for wishing!

The answer is 7

C = 2*pi*r      so we have

8.7m = 2 * pi * r     divide by 2 * pi on each side

8.7 m / [2 * pi] = r ≈ 1.38 m

Accoding to Wikipedia, the Big Bang happened about 13.8 billion years ago.

The (approximate) number of seconds in a year = 3600 x 24 x 365 = 31,536,000

So

(13.8 x 10⁹) x (3.1536 x 10⁷) = 435196800000000000 ≈ 4.351968 x 10¹⁷ seconds ago

(Of course......a few more seconds have elasped as I've been writing all of this....minor adjustments may be necessary.....)

Everyone's reality is different, Anonymous.......

Factoring the numerator and denominator, we have

[(2x + 3) (2x + 3)] / [2(2x + 3)] =

[2x + 3] / 2
