Question

Geometry help with Rohmbus figure!

Answer 1

find y please!

Answer 2

ok so we know that parallel sides of the rhombus are of equal length, so using the two equations given you can form a relationship and solve for y. 8-y=3x+12 and then solve for y

Answer 3

how would you get rid of the x though?

Answer 4

you cant get rid of it because we arent given a specific value for x so you just create an equation for y with an x in it. What did you get when you solved for y?

Answer 5

I dont know, i dont understand how to do it :/

Answer 6

ok, well work through it then :) when you have 8-y=3x+12 and you are trying to get y by itself, you have to subtract 8 from both sides. What does that give you?

Answer 7

y = 3x + 4

Answer 8

close, its actually -y=3x+4, now you have to get rid of the negative sign in front of the y to do that just change the sign of everything to the opposite of what it is now (positive to negative and negative to positive). what does that give you?

Answer 9

y = -3x - 4

Answer 10

Correct, that is your solution for y

Answer 11

Thats the answer to Y? -3x -4 ?

Answer 12

or do i add -3x to -4

Answer 13

That is, as far as i can tell, the solution to Y. No the -3x and -4 cannot be added because both terms dont have a x in them so they must be left separate.

Answer 14

I can only have 1 number though?

Answer 15

what do you mean?

Answer 16

I cant put both 3x and 4 in my answer i can only put one

Answer 17

Because I also have to find A, and X of that equation as well

Answer 18

I see, I'm not sure ill be able to help you further than that then I'm sorry, best of luck to you though!

Answer 19

its okay thank you for the help though!(:
