Solve the system of equations. If the system has no solution, say that it is inconsistent. Graph the lines of the system. \( \left\{\begin{array}{l}x+y=8 \\ x-y=2\end{array}\right. \) B. The solution is \( x=5 \) and \( y=3 \). (Type integers or simplified fractions.) ordered pairs, they can be expressed as \{( \( x, y) \mid x= \), \( y \) is any real number \( \} \) (Simplify your answer. Type an expression using \( y \) as the variable as nethed.) C. The system is inconsistent

14. Write two division sentences for \( 8 \times 6=H C \) 15. There are 80 tables in the lunchroom. There are 8 chairs around each table How many total chairs are in the gym?

11. You are given the expression \( -6^{-1} \) a. Rewrite the expression using a positive exponent. b. Reasoning simplify the expression \( -6^{-4} \) Is the result the same as simplifying the expression \( (-6)^{-4} \) ? Explain.

Simplifica: \( \frac{a^{5}}{a^{2}} \)

Analyze the polynomial function \( f(x)=x^{2}(x-8)(x+8) \) using parts (a) through (e). (a) Determine the end behavior of the graph of the function. The graph of \( f \) behaves like \( y=\square \) for large values of \( |x| \). (b) Find the \( x \) - and \( y \)-intercepts of the graph of the function. The \( x \)-intercept(s) is/are \( \square \). (Simplify your answer. Type an integer or a fraction. Use a comma to separate answers as needed. Type each answer only once.) The \( y \)-intercept is \( \square \). Type an integer or a fraction.) (Simplify your answer. Type (c) Determine the zeros of the function and their multiplicity. Use this information to determine whether the graph crosses or touches the \( x \)-axis at each \( x \)-intercept.
