a segment has endpoints at (1, -2) The midpoint is at (-4, -2). What are the cooordinates of the other endpoint?

vfiekz [6]

Answer:

coordinate of the other endpoint is (-9,-2)

Step-by-step explanation:

Given that a segment has endpoints at (1, -2). The midpoint is at (-4, -2).

Now we need to find about what are the coordinates of the other endpoint.

let the coordinates of other end points are (x,y)

Then mid point of (1,-2) and (x,y) is given by mid point formula:

$\left(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}\right)$

$\left(\frac{x+1}{2},\frac{y-2}{2}\right)=(-4,-2)$

$\Rightarrow \frac{x+1}{2}=-4, \frac{y-2}{2}=-2$

$\Rightarrow x+1=-8, y-2=-4$

$\Rightarrow x=-9, y=-2$

hence coordinate of the other endpoint is (-9,-2)

X^4-256=0 numbers of rational roots

zhuklara [117]

Answer:

x = 8 or x = -8

Step-by-step explanation:

x^4 - 256 = 0

<=>x^4 - 4^4 = 0

<=>(x - 8)(x + 8)(x^2 + 64) = 0

Case 1 :

x - 8 = 0

<=>x = 8 (choose)

Case 2:

x + 8 = 0

<=>x = -8 (choose)

Case 3:

x^2 + 64 = 0

<=>x^2 = -64 (nonsense)

so x = 8 or x = -8

Done :))
