Question

Find a point e on cd such that the ratio of ce to cd is 3/8.-7-5-3-1

Answer 1

The question is asking to choose among the following choices that states the value of the point e if the ration of ce to cd is 3/8, base on that and on my further calculation, I would say that the value of point e is -1. I hope you are satisfied with my answer and feel free to ask for more 

Answer 2

the picture in the attached figure

we have

the x- coordinate of point C is equal to
`-9`

the x- coordinate of point D is equal to
`7`

Find the distance CD

the distance CD is equal to

`dCD=7-(-9)\\ dCD=16 units`

we know that

`(CE)/(CD) =(3)/(8) \\ \\ 8CE=3CD\\ CE=(3)/(8)CD`

Find the distance CE

`CE=(3)/(8)CD\\ \\ CE=(3)/(8)*16\\ \\ CE=6units`

Find the coordinate of point E

`Point.E=Point.C+distance.CE\\ Point.E=-9+6\\ Point.E=-3`

therefore

the answer is

The coordinate of point E is
`-3`
