Write the expression in simplest radical form.

Which expression is equivalent to (3^2)^-2 a.-81 b.-12 c.1/81 d.1/12

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 this equation using substitution. {4x + y = −2} {4x + 6y = 44}
