(b) Use the slope to determine another point on the line. Write the coordinates of the point.

A ladder is leaning up against a house. If the ladder is 14 ft . long and it reaches 8 feet up the house, then what is the measure of the angle formed by the base of the ladder and the ground? (Hint - draw a sketch of the problem) The ladder and the ground forms an angle with a measure of "round values to the hundredths place**

Solve the pair of equations simultaneously \[ \begin{array}{r}3 x=3+2 y \ldots \ldots \ldots \\ x+3 y=1 \ldots \ldots\end{array} \]

15) Determinar \( x \) e \( y \) de modo que se tenha \( \left[\begin{array}{cc}y^{3} & 3 x \\ y^{2} & 4 x\end{array}\right]+\left[\begin{array}{cc}-y & x^{2} \\ 2 y & x^{2}\end{array}\right]+\left[\begin{array}{cc}-1 & 1 \\ 2 & 2\end{array}\right]=\left[\begin{array}{cc}5 & 1 \\ 10 & -1\end{array}\right] \)

\begin{tabular}{|l} Number: \\ \hline \( 3 F \) \\ From Base: \\ 16 (hexadecimal) \\ To Base: \\ 2 (binary) \end{tabular}

7. Show how the Distributive Property can make the arithmetic simpler in the following problems \( \begin{array}{ll}\text { a. } 3 \cdot(50.15) & \text { b. } 5(108)\end{array} \)
