What is the discriminant of the quadratic equation 0 = –x2 + 4x – 2?

What values of c and d make the equation true?

An equation representing lyle’s hedge-trimming business is a = 12n - 300 where a is the amount of profit or loss in dollars and n is the number of hedges trimmed. how would the graph of lyle’s business change if the equation a = 10n - 300 represented his business? the graph would be flatter. the graph would be steeper. the graph would start closer to the origin. the graph would start lower on the y-axis.

If a || b and b | y, then ? a) x || y. b) x | a. c) a | y. d) a || y.
