The "rule" I grew up with is that the hyphens are needed usually when they PRECEDE the nouns they modify. "She is an old-fashioned girl"; "He is an ill-at-ease young man"; "He is a well-known author"; "With his help I became an up-to-date student of chiropractic"; "Today," Joe said, "we will have a multiple-choice and fill-in-the-blank test"; "Our state-of-the-art technology, and our cutting-edge software are new." A good deal depends, however, on how the sentence scans as to whether your exemplars as written need hyphens. Could they scan poorly and cause confusion, forcing a re-read? – rhetorician Feb 26 '14 at 22:20
Good point. I love the word 'exemplar' as a substitute for 'example'. :-) – whippoorwill Feb 26 '14 at 22:25
This is covered at the' “object-oriented” vs “object oriented” ' thread, but this title is more user friendly. And incidentally, (4) is adjectival (a resultative construction – 'I' becoming up to date; cf 'he hammered the metal flat') not adverbial. – Edwin Ashworth Feb 26 '14 at 22:42
@rhetorician: Your comment says everything I would put in an answer. If you posted it, I'd upvote it. (Well, maybe throw in a reference to a sensible style manual, like The Economist’s—and unless Edwin is implying that this is a duplicate question.) – Daniel Harbour Feb 26 '14 at 22:58
@DanielHarbour: Thank you. I'm a little reticent to do so, but I give you permission to quote me liberally (or cut and paste the whole thing) if you'd like to provide an answer. Don – rhetorician Feb 26 '14 at 23:33

Predicate adjectives generally are not hyphenated. They gain hyphens when preceding nouns. The common appearance of hyphens in predicate adjectives seems to be a back-formation: Having seen hyphens at "up-to-date account," a writer may then type "The account was up-to-date," unnecessarily carrying the hyphens along with the rest of the expression.

Examples 6 and 7 are exceptions because of the second expression in each, which starts with a a verb or a word that can be mistaken for one. Rather than adding hyphens to the predicate adjectives though, recast them. Example 6: The test has multiple-choice and fill-in-the-blank questions. Example 7: Replace "is cutting edge" with "breaks new ground," "opens fresh horizons," "transforms user experience" (sorry: geek-speak), or whatever other substitute for "is new" that you select.
