Answer 3

@mathmale why cant I ask any questions unless its to a qualified helper?

Answer 4

Pls share any thoughts you may have regarding what to do first.

Answer 5

i have no clue :( i really dont understand this and my teacher is on a plane rn so i cant call her

Answer 6

personally I would solve this and then find out the coordinate where they touched. If you multiply the second equation by -2 then you should be able to use elimination :)

Answer 7

I know that ill "have to pay" for a qualified helper @mathmale but look I have no "post" option

Answer 8

well first off 8x - 9 = -1x
then 4x - 1 = 3x

Answer 9

whats next :)

Answer 10

okay so multiply (4x-1=y)-4

Answer 11

Rearrange your 4x - 1 = 3x so that both x terms are on the left side of your equation and your sole constant is on the right side.

Answer 12

were did you get 4x-1=3x?

Answer 13

so next is 3x - 4 ???????

Answer 14

or is it 3x * -4

Answer 15

You have 2 equtions that begin with "y=," so why not set those 2 equations = to each other?

This will eliminate y and leave y ou with x only.

Answer 16

Please show every step of your work.

Answer 17

THAT ISNT THE EQUATION

Answer 18

im confused

Answer 19

@RhondaSommer I sent u a pm

Answer 20

look at your equations. write them out for me

Answer 21

Y = 8x - 9
Y = 4x - 1

Answer 22

okay, now multiply \[(y=4x-1)-2\] and you get \[-2y=-8x+2\]

Answer 23

@RhondaSommer ok whats next ???????

Answer 24

Altho there are various ways in which to solve a system of linear equations, I recommend using one that ELIMINATES one of the variables. The very last result, above, doesn't accomplish that.

Name your method, then demonstrate its application to this problem.

Answer 25

so now you have \[y=8x-9\]and\[-2y=-8x+2\] combine them together :) \[-2y+y=8x-8x+2-9\]and you simplify to\[-y=-7\]which simplifies to \[y=7\]

Answer 26

is that everything :D

Answer 27

now, place (7) in place of (y) in the equation \[y=8x-9\] what do you get for (x)

Answer 28

2

Answer 29

this look good ????? @RhondaSommer

Answer 30

we stated that 4x-1 DID NOT equal 3x. I feel like your pulling that out of thin air. 4x-1=-y

Answer 31

none of that is what i put down either :/ I feel like you arent following me.
