For eliminating you need to have a variable that cancels the other out and in this case 2x and -2x do. Then you want to take -3y+9y and add the numbers after the equal sign. -9+3

see explanation

Step-by-step explanation:

A cube has 6 congruent square faces

The area of 1 face = \frac{2}{3} × \frac{2}{3} = \frac{4}{9}

Multiply by 6 to obtain surface area of cube

surface area = 6 × \frac{4}{9} = \frac{24}{9} = \frac{8}{3} units²

a^2 - b^2            a + b

      7ab                 a - b
= --------------  -  --------------
  (a-b)(a+b)           a + b

      7ab                 (a - b)^2
= --------------  -  -----------------------
  (a-b)(a+b)           (a + b)(a-b)

      7ab                 a^2 - 2ab + b^2
= --------------  -  -----------------------
  (a-b)(a+b)           (a + b)(a-b)

Answer:

f(x) = -x -1

Step-by-step explanation:

f(x) = mx + b

find 2 points on the line:

A( -1 , 0)

B( 0 , -1)

Put them in the equation and fine m & b:

0=m(-1)+b

-1=m(0)+b

so b= -1

and m= -1

so f(x) = -x-1
