Question Determine if the following system of equations has no solutions, infinitely many solutions or exactly one solution. \[ \begin{array}{l}-x+5 y=-8 \\ 2 x-10 y=10\end{array} \]

What should be, subtracted from \( 8 x-3 y+4 \) to get \( 3 x-2 y+4 \).

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

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

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

O Functions and Lines Evaluating functions: Linear and quadratic or cubic The functions \( f \) and \( g \) are defined as follows. \[ f(x)=-2 x^{2}-3 \quad g(x)=3 x-1 \] Find \( f(5) \) and \( g(-2) \). Simplify your answers as much as possible. \[ f(5)=\square \] \( g(-2)=\square \)
