Is (2, 5) a solution to this system of inequalities?

y ≥ x + 3
y < 4x + 2

1 answer

To determine if the point (2, 5) is a solution to the system of inequalities, we need to check whether the coordinates \(x = 2\) and \(y = 5\) satisfy both inequalities.

  1. First inequality: \(y \geq x + 3\) \[ 5 \geq 2 + 3 \] \[ 5 \geq 5 \quad \text{(true)} \] So, (2, 5) satisfies the first inequality.

  2. Second inequality: \(y < 4x + 2\) \[ 5 < 4(2) + 2 \] \[ 5 < 8 + 2 \] \[ 5 < 10 \quad \text{(true)} \] So, (2, 5) also satisfies the second inequality.

Since the point (2, 5) satisfies both inequalities, we conclude that it is indeed a solution to the system of inequalities.
