Which expression is equivalent to \( x^{-3} \cdot x^{-3} \cdot x^{2} ? \) A \( x^{-12} \) B \( \frac{1}{x^{4}} \) C \( \frac{1}{x^{-4}} \) D \( x^{18} \)

\( x^{4}-9 x^{2}+3+x \) entre \( x+3 \)

Factor completely: \[ 2 w^{3}-2 w^{3} x^{4} \]

\( 2 x-5=4 \) \( \alpha x+10 y=4 \), se satisfaga: \( \quad \forall x \quad R^{+} y \forall y \quad R \)

Solve for \( x \) \[ y-\frac{5}{x}=\frac{3}{v} \]

Solving Systems of Equations Exit Ticket 1. Mindy's high school class has a total of 150 students and they are planning a field trip. The school has smal buses and vans to transport all students. Each van can seat 8 students and each bus can seat 14 students. Ther are only 15 drivers, so the total number of vehicles that they can take must be 15 . How many of each vehicle will Mindy's class need to transport everyone?
