Write a system of equations in \( x \) and \( y \) describing the situation. Do not solve the system. A smaller number and a larger number add up to 14 and have a difference of 2 . (Let \( x \) be the larger number and \( y \) be the smaller number.)

Write the expression as a single logarithm. \( 6 \log _{c} x+7 \log _{c} y-\frac{1}{3} \log _{c} z \) A. \( 6 \log _{c} x+7 \log _{c} y-\frac{1}{3} \log _{c} z=\log _{c} \frac{y^{7} z^{1 / 3}}{x^{6}} \) B. \( 6 \log _{c} x+7 \log _{c} y-\frac{1}{3} \log _{c} z=\log _{c} \frac{x^{6} y^{7}}{z^{3}} \) O. \( 6 \log _{c} x+7 \log _{c} y-\frac{1}{3} \log _{c} z=\log _{c} \frac{x^{6} y^{7}}{z^{1 / 3}} \) O. \( 6 \log _{c} x+7 \log _{c} y-\frac{1}{3} \log _{c} z=\log _{c} \frac{x^{6} z^{1 / 3}}{y^{7}} \)

\( 1 \leftarrow \quad \) Given vectors \( \mathbf{u} \) and \( \mathbf{v} \), find (a) \( 7 \mathbf{u} \) \( \mathbf{u}=6 \mathbf{i}, \mathbf{v}=3 \mathbf{i}+6 \mathbf{j} \) (b) \( 7 \mathbf{u}+2 \mathbf{v} \) (c) \( \mathbf{v}-2 \mathbf{u} \). (a) \( 7 \mathbf{u}=42 \mathbf{i} \) (Type your answer in terms of iand \( \mathbf{j} \).) (b) \( 7 \mathbf{u}+2 \mathbf{v}=\square \) (Type your answer in terms of \( \mathbf{i} \) and \( \mathbf{j} \).)
