Given the endpoint (-9,3) and (1,8) partition the segment into the ratio 2:3<br>

Sindrei [870]

Answer:

$P = (-5,5)$

Step-by-step explanation:

Let the segments be A and B

$A = (-9,3)$

$B = (1,8)$

$m:n = 2:3$

Required

Determine the endpoints after it is divided into ratios.

<em>Let the point be represented with P</em>

The formula to use is:

$P = (\frac{mx_2 + nx_1}{m + n},\frac{my_2 + ny_1}{m + n})$

Where

$A = (-9,3)$ ----- $(x_1,y_1)$

$B = (1,8)$ ------ $(x_2,y_2)$

So:

$P = (\frac{mx_2 + nx_1}{m + n},\frac{my_2 + ny_1}{m + n})$

$P = (\frac{2 * 1 + 3 * -9}{2 + 3},\frac{2 * 8 + 3 * 3}{2 + 3})$

$P = (\frac{-25}{5},\frac{25}{5})$

$P = (-5,5)$

How many solutions do these equations have y= 3x+4 y+6=3x

Nataly [62]

Answer:

Step-by-step explanation:

hello :

the system is : y= 3x+4....(*)

y+6=3x....(**)

by (**) : y = 3x - 6

so : y= 3x+4

y= 3x - 6

means : 3x+4 = 3x - 6

4= -6.......(false)

conclusion : no reals solutions
