2. (10 points) Use either the substitution method or the addition method to find the complete solution of the system, or show that no solution exists. If there are an infinite number or solutions, then find a formula for the solutions.
\( \left\{ \begin{array} { l } { 2 x + 6 y + 4 z = 10 } \\ { x + y + z = 6 } \\ { x + 3 y + 2 z = 5 } \end{array} \right.\)
infinite solutions
x=\(\frac{13}{2} - \frac{z}{2}\)
y=\(- \frac{1}{2} - \frac{1}{2} z\)
The first three terms of a sequence are given. Round to the nearest thousandth (if necessary).
\( 8,40,200 , \ldots \)
Find the \( 10 \) th term.
(1) q) Put \( S \) above any dash that represents subtraction, \( N \) above any dash that represents negative and \( O \) above any dash that represents opposite. NOTE: You only need to give one answer if more than one answer is possible for a dash.
\( - ( 2 - ( - 3 ) ) - ( - 4 + ( - 2 ) ) + 4 ( - 5 ) + ( - ( - 3 ) )\)
