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.

Solve each quadratic equation by factoring and using the zero product property. x^2 - 8x + 30 = 3x

Select the conic section that represents the equation. 3x2 + 3y2 -2x + 4 = 0
