Point B is on line AC so that AB : BC = 2 : 1. Point D is on line AB so that AD : DB = 3 : 2. Find AD : DC
Leya [2.2K]

Firstly, we will draw figure

Let's assume

length of AC=x

we have

AB : BC = 2 : 1

so,

AB=\frac{2}{3} x

BC=\frac{1}{3} x

Point D is on line AB

and

AB=\frac{2}{3} x

AD : DB = 3 : 2

so, we get

AD=\frac{3}{5} *\frac{2}{3} x

AD=\frac{2}{5} x

DB=\frac{2}{5} *\frac{2}{3} x

DB=\frac{4}{15} x

now, we can locate these values

Firstly, we will find DC

DC=DB+BC

now, we can plug values

DC=\frac{4}{15} x+\frac{1}{3} x

DC=\frac{3x}{5}

we have got

AD=\frac{2}{5} x

now, we can find ratio

\frac{AD}{DC} =\frac{\frac{2}{5} x}{\frac{3x}{5}}

now, we can simplify it

\frac{AD}{DC} =\frac{2}{3}

so,

AD:DC=2:3...........Answer

Can I get a answer ASAP please I would greatly appreciate it
Nina [5.8K]

Answer: <u>A</u>

Step-by-step explanation:

Domain is based off of the x-axis (left to right).

The curve starts at -1, and ends at 3. Therefore, x is greater than, or equal to -1, and x is less than, or equal to 3.

Also note that the dots signifying the beginning and end of the line is filled in (completely black). If the dot was not filled in, that's basically saying that line <em>doesn't</em> include the number the dot is on.
