Answer:

To find the inequality for which x equals 4 is a solution, we can plug in x = 4 into each inequality and see which one is true.

Let's consider the following inequalities:

(a) x + 3 < 10

(b) 2x - 5 > 7

(c) 5x/2 + 2 >= 14 - x

(d) x^2 - 16x + 64 > 0

(a) x + 3 < 10

When x = 4, we get:

4 + 3 < 10

7 < 10

This is true, but x = 4 is not a solution to this inequality.

(b) 2x - 5 > 7

When x = 4, we get:

2(4) - 5 > 7

3 > 7

This is false, so x = 4 is not a solution to this inequality.

(c) 5x/2 + 2 >= 14 - x

When x = 4, we get:

5(4)/2 + 2 >= 14 - 4

10 + 2 >= 10

This is true, so x = 4 is a solution to this inequality.

(d) x^2 - 16x + 64 > 0

When x = 4, we get:

4^2 - 16(4) + 64 > 0

0 > 0

This is false, so x = 4 is not a solution to this inequality.

Therefore, the inequality for which x equals 4 is a solution is 5x/2 + 2 >= 14 - x.

Hope this helps!
