Segment AB is shown on the graph. Which shows how to find the x-coordinate of the point that will divide segment AB into a 2:3 r

GrogVix [38]

Answer:

$x=\dfrac{2}{5}\times (2+3)-3$

Step-by-step explanation:

The given ratio is 2:3.

x₁ = -3, x₂ = 2

We need to find the x-coordinate of the point that will divide segment AB into a 2:3 ratio. The formula is as follows :

$x=\dfrac{a}{a+b}(x_2-x_1)+x_1$

Put all the values,

$x=\dfrac{2}{2+3}(2-(-3))+(-3)\\\\=\dfrac{2}{5}\times (2+3)-3$

Hence, the correct option is (d).
