Robyn incorrectly solved a rational equation. her work is shown. what error did she make?

In the second step while distributing she made a mistake

It should have been

2x^2 -4x -6x +18 = 9x - 27

So answer should be

She did not use the distributive property correctly

she didn't distribute properly

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
