Question

geometry help just a few simple questions please!

Answer 1

i'll try.

Answer 2

okay the first two are just equations i need help solving..

x+1=3y

and 8x+8+7x+4

Answer 3

2. 15x=12.

Answer 4

huh?

Answer 5

@jim_thompson5910 help me lol please

Answer 6

...

Answer 7

solving for x

x+1=3y

x = 3y - 1

-------------------------------------------------------

Solving for y

x+1=3y

3y = x+1

y = (x+1)/3

Answer 8

The basic idea is to isolate the desired variable in terms of the other variable

Answer 9

8x+8+7x+4

(8x+7x)+(8+4)

15x + 12

So 8x+8+7x+4 simplifies to 15x + 12

Answer 10

i am able to get x+1=3y too but what do i do from there? same for y

Answer 11

you want to solve x+1 = 3y for y right?

Answer 12

yes sir

Answer 13

first flip the equation, then divide both sides by 3 to isolate y


\[\Large x+1 = 3y\]


\[\Large 3y = x+1\]


\[\Large y = \frac{x+1}{3}\]

Answer 14

i still dont get it jim:/

Answer 15

you basically want y = ...

ie you want y all by itself on one side

Answer 16

to isolate y, you have to divide both sides by 3 to undo multiplication of 3

Answer 17

okay so what do i do now

Answer 18

I'm not sure did you want to graph? some of the instructions seem missing on this one

Answer 19

yea here ill post the whole thing bc im getting confused too lol

Answer 20

9. In parallelogram DEFG, DH = x + 1, HF = 3y, GH = 3x – 4, and HE = 5y + 1. Find the values of x and y. The diagram is not drawn to scale.
this one has nothing to do with the 8x+8 equation that one is seprate

Answer 21

omg wrong picture lol hold on

Answer 22

wrong pic? lol

Answer 23

alright, thats ok

Answer 24

omg hold on

Answer 25

there we go lol

Answer 26

10. If ON = 8x – 8, LM = 7x + 4, NM = x – 5, and OL = 3y – 6, find the values of x and y for which LMNO must be a parallelogram. The diagram is not drawn to scale.


this is the other one

Answer 27

wow guys.

Answer 28

what

Answer 29

If LMNO is a parallelogram, then

ON = LM

8x - 8 = 7x + 4

solve for x

--------------------------------------

Also, if LMNO is a parallelogram, then

NM = OL

x-5 = 3y - 6

Plug the solution you got for x, then solve for y.
