When solved correctly, the equation \( \sqrt { - 2 x - 5 } = x + 4 \) has solutions of \( x = - 7 \) and \( x = - 3 \) . Which, if any, of the solutions are extraneous?  Both \( x = - 7 \) and \( x = - 3 \) are extraneous. Only \( x = - 7 \) is extraneous. Neither solution is extraneous. Only \( x = - 3 \) is extraneous. 

\( 1<\quad \begin{array}{r}\text { Determine whether the ordered pair }(4,5) \text { is a solution of the system. } \\ \begin{array}{r}3 x+2 y=2 \\ 2 x+y=3\end{array}\end{array} \)

\( 1 \leftarrow \quad \begin{array}{r}\text { Solve the system of equations by the substitution method. } \\ \begin{aligned} x+y & =-2 \\ y & =-2 x\end{aligned}\end{array} \)

/Evaluate \( :\left(\frac{4^{-8}}{8^{-4}}\right)^{3 / 4} \)

\( 1 \leftarrow \quad \begin{array}{l}\text { Solve the system of equations by the substitution method. } \\ \begin{aligned} 4 x+2 y & =-154 \\ x-5 y & =0\end{aligned}\end{array} \)

Evaluating functions: Linear and quadratic or cubic The functions \( f \) and \( g \) are defined as follows. \( f(x)=3 x^{3}+5 \quad g(x)=-5 x+4 \) Find \( f(-2) \) and \( g(7) \). \[ f(-2)=\square \] \( g(7)=\square \)
