Step-by-step explanation:

log(7x³/z) = log(7) + log(x³) - log(z).

3log(5) + 2log(x) - log(25) = log(125) + log(x²) - log(25) = log(125x²/25) = log(5x²).

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)
