(3,3) (3,3) endpoints of a vertical line, a horizontal line, or neither?

Will give find an equivalent function to f(x)=5(2)^3x. the 5(2)^3x means 5(2) to the 3x power answer choices: a: f(x)=125^x(8)^x b: f(x)=10^2x c: f(x)=40^x d: f(x)=5(8)^x

What values of x satisfy the inequality x^2-9x< 0? how is your answer shown on the graph?

Divide. reduce the answer to lowest terms.5 2/3 ÷ 3 1/9
