To determine if the point (3, 8) is a solution to the simultaneous inequalities \( y > x + 5 \) and \( y \leq 6x - 3 \), we need to check each inequality:

  1. For the inequality \( y > x + 5 \):

    • Substitute \( x = 3 \) and \( y = 8 \): \[ 8 > 3 + 5 \implies 8 > 8 \] This is not true because 8 is not greater than 8.
  2. For the inequality \( y \leq 6x - 3 \):

    • Substitute \( x = 3 \) and \( y = 8 \): \[ 8 \leq 6(3) - 3 \implies 8 \leq 18 - 3 \implies 8 \leq 15 \] This is true because 8 is less than or equal to 15.

Based on this analysis:

  • The point (3, 8) is not a solution for the first inequality \( y > x + 5 \).
  • The point (3, 8) is a solution for the second inequality \( y \leq 6x - 3 \).

Therefore, the correct response is:

No, it is in the solution set for \( y \leq 6x - 3 \), but on the line for \( y > x + 5 \).
