Factor the following expression completely given that one of the roots is 5 : \( z^{3}-6 z^{2}-85 z+450=\square \)

replace \( f(x) \) with \( y \), switch \( x+y \) in ed 7. Given the function defined by \( g(x)=\sqrt{x+2}-5 \), find the inverse function \( g^{-1}(x) \)

23. Given the equation \( y=\frac{3}{4} x-5 \), what is the slope and \( y \)-intercept of the line? The slope of the line is 5 , and the \( y \)-intercept is \( \left(0, \frac{3}{4}\right) \). The slope of the line is \( \frac{3}{4} \), and the \( y \)-intercept is \( (0,5) \). The slope of the line is -5 , and the \( y \)-intercept is \( \left(0, \frac{3}{4}\right) \). The slope of the line is \( \frac{3}{4} \), and the \( y \)-intercept is \( (0,-5) \).

Give the \( y \)-interecept \[ 3 x+y=5 \]

Solve for x: \( 3^{x} = 81 \).

Simplify. Assume that variable \( z \) is nonzero. \( y^{5} z^{-9} \)
