Using the polynomials q = 3x 2 + 5x - 2, r = 2 - x 2, and s = 2x + 5, perform the indicated operation. q - [r + s] 2x2 + 3x - 9 4x2 - 3x + 9 2x2 - 3x + 9 4x2 + 3x - 9

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.
