Is (1, 2) a solution to this system of inequalities?

4x + y >= 6

4x + 3y > 10

1 answer

To determine if the point \( (1, 2) \) is a solution to the system of inequalities, we will substitute \( x = 1 \) and \( y = 2 \) into each inequality and check if the inequalities hold true.

  1. First Inequality: \( 4x + y \geq 6 \) \[ 4(1) + 2 \geq 6 \] \[ 4 + 2 \geq 6 \] \[ 6 \geq 6 \quad \text{(True)} \]

  2. Second Inequality: \( 4x + 3y > 10 \) \[ 4(1) + 3(2) > 10 \] \[ 4 + 6 > 10 \] \[ 10 > 10 \quad \text{(False)} \]

Since the point \( (1, 2) \) satisfies the first inequality but does not satisfy the second inequality, it is not a solution to the system of inequalities.

In conclusion, \( (1, 2) \) is not a solution to the system of inequalities.
