Part A A tie-dye kit with one T-shirt costs \( \$ 15 \). Each additional T-shirt costs \( \$ 4 \) more. Choose the explicit formula to represent the situation. A. \( a_{n}=11+4 n \) B. \( a_{n}=4+15 n \) Cl. \( a_{n}=19+4 n \) Kids

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 \( \$ 1000 \).

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

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 \( f(x)= \)

Para cuáles números x la expresión \( 16 \times 2+2 x-35 \) toma valores menores que los de \( 2 x+65 \).

\( \left. \begin{array} { c } { x + y + z = 6 } \\ { \left. \begin{array} { c } { 3 x - 2 y + 6 z = 11 } \\ { x + z = 7 } \end{array} \right. } \end{array} \right. \Rightarrow \left[ \begin{array} { c c c c } { 1 } & { 1 } & { 1 } & { 6 } \\ { 3 } & { - 2 } & { 6 } & { 1 } \\ { 1 } & { 0 } & { 1 } & { 7 } \end{array} \right] \)
