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.

Consider the proof. given: segment ab is parallel to line de. prove: what is the missing statement in step 5?

What is the number 321,000,000 in scientific notation? also what is the number? ?
