Solve each equation. Remember to check for extraneous solutions! 1. 4/9 = x-7/x+1

2. 1/6r^2 + 2r-6/3r^2 = 1/3r^2

3. x^2-3x/x^2+4x+3 + 1/x+1 = 1/x+3

1. 67/5

2. r=12/13, 0

3. x≈−3.46050487, −1.23912327, 0.69962814

Hope this helps

the answer to the question is a  

it has the same slope and the same y-intercept.

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
