When u = 17, solving -u + 4 ≥ -3:

1. Substitute: -17 + 4 ≥ -3.

2. Simplify to -13 ≥ -3, true.

Therefore, u = 17 satisfies the inequality, showing -u + 4 ≥ -3 holds true.

Let's reevaluate the inequalities to confirm the correct one when u = 17:

a) -u + 4 ≥ -3

-17 + 4 ≥ -3

-13 ≥ -3 (This is true)

b) u + 4 ≤ -3

17 + 4 ≤ -3

21 ≤ -3 (This is not true)

c) -u + 4 < 3

-17 + 4 < 3

-13 < 3 (This is true)

d) -u + 4 ≥ 3

-17 + 4 ≥ 3

-13 ≥ 3 (This is not true)

Upon re evaluation, it's clear that the correct inequality when u = 17 is:

a) -u + 4 ≥ -3

And as correctly pointed out in your assessment:

c) -u + 4 < 3 is also true when u = 17.
