In una gita scolastica ogni insegnante accompagna un gruppo oi 12 studenti. Se alla gita partecipano 132 studentl, quanti insegnanti occorrono?

Find the zeros of the following quadratic function using the square root method. What are the \( x \)-intercepts of the graph of the function? \( f(x)=x^{2}-98 \) Select the correct choice below and fill in the answer box to complete your choice. (Simplify your answer, including any radicals. Use integers or fractions for any numbers in the expression. Use a comma to separate answers as needed.) B. The zeros and the \( x \)-intercepts are the same. They are B. Therepts are different. The zeros are

Let \( F(x)=x^{2}-2 \) and \( G(x)=3-x \)

Question 2 Find the smallest value of \( n \) that produces an \( x^{-9} \) term in the expansion of \( x^{-2}\left(\frac{7}{x^{3}}+5 x^{5}\right)^{n} \), where \( n \in \mathbb{Z} \) .

b) Sketch the following lines on the same set of axes using the dual-intercept method: \( \begin{array}{lll}\text { (1) } y=x+1 & \text { (2) } y=x-1 & \text { (3) } y=x+2 \\ \text { (4) } y=x-2 & \text { (5) } y=x+3 & \text { (6) } y=x-3 \\ \text { (7) } y=x+4 & \text { (8) } y=x+4 & \text { (9) } y=x-5\end{array} \)

Which of the following is a value of \( x \) for which the expression \( \frac{-3}{x^{2}+3 x-12} \) is undefined?
