All Rational zerai \( 2 x^{5}+8 x^{3}+7 x^{2}-6 \)

3. The greater of two numbers is one less than 8 times the smaller. Their sum is 98 . Find the numbers.

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

a. \( (f \circ \mathrm{~g})(\mathrm{x})=\frac{23-2 \mathrm{x}}{5 \mathrm{x}-19} \) (Factor completely. Simplify your answer.) What is the domain of \( \mathrm{f} \circ \mathrm{g} \) ? Select the correct choice below and, if necessary, fill in the answer box to complete your cho (Use a comma to separate answers as needed. Use integers or fractions for any numbers in the expression.) B. The domain is all real numbers.

Solve for \( w \) \[ 3 w^{2}+12 w=0 \]

Use substitution to solve the system. \[ \begin{array}{c}3 x+5 y=-7 \\ 3 y+7=x\end{array} \]
