2. Esteban counted the number of steps it took him to walk to school. He counted 1,138 steps. How many steps does he take walking to and from school each day?

1. \( \sqrt{\frac{1}{3}} \div \sqrt{\frac{1}{11}} \) 2. \( \sqrt{7} \div \sqrt{18} \) 3. \( \frac{\sqrt{378}}{\sqrt{7}} \) 4. \( \frac{3 y^{2}}{\sqrt{2 y}} \) 5. \( \frac{y}{\sqrt[3]{4 y}} \)

Solve the system of equations. If the system has no solution, say that it is inconsistent. \( \left\{\begin{array}{r}6 x-5 y=6 \\ 30 x+5 y=36\end{array}\right. \) Select the correct choice below and, if necessary, fill in any answer boxes within your choice. A. The solution is \( x=\square \) and \( y=\square \). (Type integers or simplified fractions.) B. There are infinitely many solutions. Using ordered pairs, they can be expressed as \( \{(x, y) \mid x=\square \), \( y \) any real number \}. (Simplify your answer. Type an expression using \( y \) as the variable as needed.) C. The system is inconsistent.

1. \( y=x^{3}+x^{2}-12 x \) 2. \( y=(x-2)(x-1)(x+3) \) 3. \( y=2 x^{4}+8 x^{3}+4 x^{2}-8 x-6 \) 5. \( y=x^{5}+10 x^{3}-9 x \)

O valor total recebido pelos motoristas de um determinado aplicativo é uma função afim, com um valor fix de \( R \$ 6,25 \) por corrida mais R\$ 1,25 por quilômetro rodado. A) Sabendo que um motorista desse aplicativo realizou 8 corridas em um dia, determine a expressão que modela o valor total recebido pelo motorista nesse dia, em função de \( x \) quilômetros rodados. B) Quantos quilômetros esse motortista percorreu se, no final do dia, ele recebeu R\$ 300,00 ?
