No, it is in the solution set for y less-than-or-equal-to 6 x minus 3 , but on the line for y greater than x plus 5 .

Yes, because both of these inequalities include points on the line as a solution.
Yes, because both of these inequalities include points on the line as a solution.

Yes, it is within the solution set for both inequalities.

Answer 1

To determine if the point (3, 8) is a solution to the simultaneous inequalities \( y > x + 5 \) and \( y \leq 6x - 3 \), we will evaluate each inequality with this point.

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

   Plug in \( x = 3 \) and \( y = 8 \): \[ 8 > 3 + 5 \] \[ 8 > 8 \] This statement is false because 8 is not greater than 8. Thus, the point (3, 8) does not satisfy this inequality.

2. Check the second inequality: \( y \leq 6x - 3 \)

   Again, plug in \( x = 3 \) and \( y = 8 \): \[ 8 \leq 6(3) - 3 \] \[ 8 \leq 18 - 3 \] \[ 8 \leq 15 \] This statement is true because 8 is indeed less than or equal to 15.

Since the point (3, 8) satisfies the second inequality but does not satisfy the first inequality, the appropriate response is:

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