line segment with one endpoint at (2,5) is divided in the ratio 4:5 by the point (10,1). which coordinates could represent the o

rodikova [14]

Answer:

(20,-4)

Step-by-step explanation:

We are given;

One end point as (2,5)

Point of division as (10,1)

The ratio of division as 4:5

We are required to calculate the other endpoint.

Assuming the other endpoint is (x,y)

Using the ratio theorem

If the unknown endpoint is the last point on the line segment;

Then;

$\left[\begin{array}{ccc}10\\1\end{array}\right]$ = $\frac{4}{5} \left[\begin{array}{ccc}x\\y\end{array}\right]$ + $\frac{5}{9}\left[\begin{array}{ccc}2\\5\end{array}\right]$

Therefore; solving the equation;

$10=\frac{4}{9}x+\frac{10}{9}$

solving for x

x = 20

Also

$1=\frac{4}{9}y+\frac{25}{9}$

solving for y

y= -4

Therefore,

the coordinates of the end point are (20,-4)

Write a quadratic equation that can be solved by factoring. Solve your equation and show and explain all your work.

miv72 [106K]

Answer:

An example of a quadratic equation is:

${x}^{2} + 5x + 6 = 0$

Step-by-step explanation:

This answer follows the standard form for a quadratic equation:

$a {x}^{2} + bx + c = 0$

To solve this equation you do the following:

x^2 + 5x + 6 =0

The factors that can be added to get *5* and multiplied to get *6* are 3 & 2.

Therefore the new equation would be:

x^2 +3x + 2x + 6 = 0

group the terms: (x^2 +3x) (+2x + 6) = 0

factorize: x (x + 3) 2 (x + 3) = 0

therefore: (x + 2) (x + 3) =0

x = -1 x =-3
