- True/False -
All imaginary numbers are complex
The sum of two non-real numbers is always non-real
If a decimal does not terminate it is always irrational
If a number is complex it must contain an imaginary component.
(Thank you so much)

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.
