Find the point P that is 2/5 of the way from A to B on the directed line segment AB
Kruka [31]

The point P(–4, 4) that is \frac{2}{5} of the way from A to B on the directed line segment AB.

Solution:

The points of the line segment are A(–8, –2) and B(6, 19).

P is the point that bisect the line segment in \frac{2}{5}.

So, m = 2 and n = 5.

x_1=-8, y_1=-2, x_2=6, y_2=19

By section formula:

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

$P(x, y)=\left(\frac{2\times 6+5\times (-8)}{2+5}, \frac{2\times 19+5\times (-2)}{2+5}\right)

$P(x, y)=\left(\frac{12-40}{7}, \frac{38-10}{7}\right)

$P(x, y)=\left(\frac{-28}{7}, \frac{28}{7}\right)

P(x, y) = (–4, 4)

Hence the point P(–4, 4) that is \frac{2}{5} of the way from A to B on the directed line segment AB.

Please help me because I don't understand how to do it.:)
shutvik [7]

Answer:

y= 1/3 x +5

Step-by-step explanation:

To find the slope, we take two points

(0,5)   and (15,10)

The slope is found by the formula

m = (y2-y1)/ (x2-x1)

   = (10-5)/(15-0)

   = 5/15

   = 1/3

The slope is 1/3

The y intercept is found when x=0

When x=0  y=5

The slope intercept form of the line is

y=mx+b  where m is the slope and b is the y intercept

y= 1/3 x +5

Divide a 5-inch line into two parts so that one part (a) 2 1/4 inches shorter than the other; (b) 3 times the other.
Ilia_Sergeevich [38]
Part a), solve this system of equations:
x + y = 5
x - y = 2.25
2x = 7.25
x = 3.625
y = 1.375

part b), solve this system of equations:
x + y = 5
x = 3y
y = 1.25
x = 3.75

Schach [20]

Answer:

All of them are parallel

Step-by-step explanation:

This is due to the all of the 90 degree angle which would make the rest of the line a would be another 90 degree angle Which are found on every line. This would make all of the lines parallel because it is a total of 180 degrees.
