Is (2, 10) a solution to this system of inequalities?

y ≥ x + 9
y > 3x + 3

1 answer

To determine if the point (2, 10) is a solution to the given system of inequalities, we'll substitute \( x = 2 \) and \( y = 10 \) into each inequality.

  1. For the first inequality \( y \geq x + 9 \):

    Substitute \( x = 2 \) into the inequality:

    \[ y \geq 2 + 9 \implies y \geq 11 \]

    Now, substituting \( y = 10 \):

    \[ 10 \geq 11 \quad \text{(False)} \]

  2. For the second inequality \( y > 3x + 3 \):

    Substitute \( x = 2 \) into the inequality:

    \[ y > 3(2) + 3 \implies y > 6 + 3 \implies y > 9 \]

    Now, substituting \( y = 10 \):

    \[ 10 > 9 \quad \text{(True)} \]

Since (2, 10) does not satisfy the first inequality but does satisfy the second, it is not a solution to the system of inequalities.
