Question

find the location ( or coordinate ) of the point C if M is the midpoint of DC. D=-24 M=-9

Answer 1

what is the distance between -24 and -9?

Answer 2

thats what i need to know i need the midpoint of that

Answer 3

no. that's the midpoint..you're looking for twice of that distance

Answer 4

so basically the plan is you get the distance from -24 to -9 then multiply it by 2

Answer 5

oh ok i just dont know how to do that

Answer 6

you do this |-24 - (-9)|

im sure you're familiar with the signs i used?

Answer 7

uh i think its -15 right?

Answer 8

that's -24 - (-9)

but note there's a | | sign that means absolute value so you need to make it positive

so the distance is 15. got it?

Answer 9

ya ok so the answer is 15?

Answer 10

nope. that's just the midpoint. now multiply it by 2

Answer 11

so 30

Answer 12

now since you're looking for the coordinate of C.. add 30 to -24

Answer 13

6

Answer 14

that's the answer now

Answer 15

ok thank you!

Answer 16

you're welcome
