Point a is located at (0, 4), and point b is located at (−2, −3). find the x value for the point that is 1 over 4 the distance from point a to point b.
−1.5

−0.5
−1

The value of x is -0.5 ⇒ 3rd answer

Step-by-step explanation:

* Lets explain how to find a point which divides a line into two parts

- If point (x , y) divides a line whose endpoints are (x1 , y1) and (x2 , y2)

 at ratio m1 : m2 from (x1 , y1) to (x2 , y2), then

* Lets solve the problem

∵ Point A located at (0 , 4)

∵ Point B located at (-2 , -3)

∵ Point (x , y) located at 1/4 the distance from A to B

- That means the distance from A to point (x , y) is 1/4 the distance

  from point A to point B

∴ The distance from A to B is divided into four equal parts, where

   the distance between point A and point (x, y) is one and the

   distance between point (x, y) and point B is three

∴ Point (x , y) divide the line AB at ratio 1 : 3 ⇒ (1 + 3 = 4)

* Now lets find the x

∵ x-coordinate of point A is 0

∴ x1 = 0

∵ x-coordinate of point B is -2

∴ x2 = -2

∵ m1 = 1 , m2 = 3

- By using the rule above

∴

* The value of x is -0.5

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x
