If f(x) = 5x2 - 3x , what is f(-3)

Find two rational expressions that have the difference of 2-n/n-4

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.

What is the slope of the line that contains the points (-2,1) and (0,-3)
