What is 1/2 to the negative power of 2 using exponent rules

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.

Write the point-slope form of the line passing through (2, -12) and parallel to y=3x.

Given ab and cb are tangents of p, and m =10°. what is the measure of abp?
