Which equation is represented by the model? 3x2 – 4x – 1 = (3x + 1)(x – 1) 3x2 – 2x – 1 = (3x – 1)(x + 1) 3x2 – 4x + 1 = (3x – 1)(x – 1) 3x2 – 2x + 1 = (3x – 1)(x – 1)

The correct option is 3.

Step-by-step explanation:

In option 1,

The given equation is

Simplify the right sides.

Since left hand side is not equal to right hand side, therefore option 1 is incorrect.

In option 2,

The given equation is

Simplify the right sides.

Since left hand side is not equal to right hand side, therefore option 2 is incorrect.

In option 3,

The given equation is

Simplify the right sides.

Since left hand side is equal to right hand side, therefore option 3 is correct.

In option 4,

The given equation is

Simplify the right sides.

Since left hand side it not equal to right hand side, therefore option 4 is incorrect.

use substitution to solve each system of equations. y = x + 5 3x + y = 25 62/87,21 y = x + 5 3x + y = 25 substitute x + 5 for y in the second equation. substitute the solution for x into either equation to find y. the solution is (5, 10)
