Answer 3

Checking the Inequality for a Given Value

To check if a given number is a solution to the inequality 4x + 5 > 17, we can substitute the given number into the inequality and see if the resulting statement is true.

Let's start by substituting a = -2 into the inequality:

4*(-2) + 5 > 17 -8 + 5 > 17 -3 > 17

The statement -3 > 17 is false, so a = -2 is not a solution to the inequality.

Now, let's substitute a = 5 into the inequality:

4*5 + 5 > 17 20 + 5 > 17 25 > 17

The statement 25 > 17 is true, so a = 5 is a solution to the inequality.

Conclusion

Based on the calculations, a = 5 is a solution to the inequality 4x + 5 > 17, while a = -2 is not a solution.
