Determine whether the function is one-to-one. If it is, find a formula for its inverse. \( f(x)=9 x-5 \) Is the function one-to-one? No Yes Find a formula for the inverse if it exists. Select the correct choice below and fill in any answer boxes within your choice. A. \( r^{-1}(x)=\square \) (Simplify your answer.) B. There is no inverse function.

Use the elimination method to find all solutions of the system: \( \left\{\begin{array}{l}x^{2}-2 y=7 \\ x^{2}+5 y=14\end{array}\right. \) The two solutions of the system are: (the one with \( x<0 \) is) \( x=\square \) \( y=\square \) (the one with \( x>0 \) is) \( x=\square \) \( y=\square \)

Question 2 of 25 After the drama club sold 100 tickets to a show, it had \( \$ 300 \) in profit. After the next show, it had sold a total of 200 tickets and had a total of \( \$ 700 \) profit. Which equation models the total profit, \( y \), based on the number of tickets sold, \( x \) ?

5. Bestäm värdet på \( a \) så att olikheten \( 2 x-a<5 \) har lösningen \( x<7 \)

\( \frac { 3 ) } { 3 x + 4 } = \frac { 2 x - 8 } { 3 } \)

14. Uttrycken nedan har samma positiva värde på \( a \). Vilka tal ska stå i rutorna så att likheterna stämmer? \( a^{\frac{1}{3}}=\square \quad a^{\frac{2}{3}}=9 \)
