Question

Find the y value for point I such that DI and EI form a 3:5 ratio.

d=(-3,2)
e=(5,5)

Answer 1

James: Sounds as tho' there should be an illustration to go with this problem. Would you post it, please?

Answer 2

ok

Answer 3

What have you done so far towards solving this problem?

Answer 4

i have another question besides this one actually. sorry for the wait

Answer 5

Find the midpoint of diagonal WY.

Answer 6

What about the question you originally posted?

Answer 7

never mind that one, i have a bigger problem with this one

Answer 8

If you post a problem, I assume you want to work on that problem. I've already invested some time and effort into solving the first problem.

In your second problem you want to find the midpoint of the diagonal of this rectangle. What are your thoughts about how to do that? Draw on your past experience.

Answer 9

x1+x2/2 y1+y2/2 and then you have your answer

Answer 10

Recognizing that the midpoint of the diagonal is also the center of the figure.
Yes, you're on the right tract, but to be mathematically correct, you'll need to enclose those coordinates x1 and x2 within parentheses; same for y1 and y2.

Write the coordinates of the midpoint of the diagonal.

It will look like this:

( ( ? + ? )/2, ( ? )/2 )

Answer 11

Without parentheses, your expression might be interpreted as x1 + x2/2 , which is incorrect here.

Answer 12

ok (0+6/2) (2+6/2)

Answer 13

(0+6/2), (2+6/2

Answer 14

thank you for trying. Actually, you want to enclose 0 and 6 within parentheses, not 0 and 6/2. Please write this in the form

( (0+6)/2, ? )

Answer 15

where you place your parentheses tells the reader which math operation to do first, so this placement is really important.

Answer 16

ohhh ok (0+6)/2, (2+6)/2

Answer 17

Now if you'll enclose all of (0+6)/2, (2+6)/2 within parentheses, you'll have the coordinates of the midpoint of the diagonal:

( (0+6)/2, (2+6)/2 )

Now please simplify that.

Answer 18

(3,,4)

Answer 19

im sorry (3,4)

Answer 20

Cool. thank you for your persistence. Nice work.

Answer 21

thanks for your patience mathmale

Answer 22

Sure! Have a great day, James. Over and out.
