Multiply. 10) \( (5 m+2)^{2} \) Simplify. There should be no negative exponents in your final answer. 11) \( x-x^{-4} \) Simplify the expression. Write the answer using enly positive exponents. 12) \( \frac{7 x-4}{y^{-3} z^{6}} \)

23. REASONING A student theater charges \( \$ 9.50 \) per ticket. a. The theater has already sold 70 tickets. Write and solve an inequality that represents how many more tickets the theater needs to sell to earn at least \( \$ 1000 \). b. The theater increases the ticket price by \( \$ 1 \). Without solving an inequality, describe how this affects the total number of tickets needed to earn at least \( \$ 1000 \).

1. Given that \( f(x)=x^{2}, g(x)=\frac{2}{x} \) and \( h(x)=2 x \), Find the following: \( \begin{array}{ll}\text { (a) } g(h(x)) & \text { (b) } f^{-1}(h(x)) \\ \text { (c) } h(f(-1)) & \text { (d) } g^{-1}(f(-1)) \\ \text { (e) } g(h(f(x))) & \text { (f) } h^{-1}(f(g(x)))\end{array} \)

The total of \( x \) and 78 is 24

Factor the polynomial function \( f(x)=4 x^{3}+20 x^{2}+29 x+10 \) Note: Write \( \left(x-\frac{a}{b}\right) \) as \( (b x-a) \) The zeros are \( f(x)= \)

\( x+y+z=6 \) \( 3 x-2 y+6 z=11 \) \( x+z=7 \) Selesaikan porsamaun ini dengan operas baris elementer-dengan actem porcyection.
