Let's solve your equation step-by-step.<span><span><span><span>−2</span>+<span>5x</span></span>−7</span>=<span><span><span>3x</span>−9</span>+<span>2x</span></span></span>
Step 1: Simplify both sides of the equation.<span><span><span><span>−2</span>+<span>5x</span></span>−7</span>=<span><span><span>3x</span>−9</span>+<span>2x</span></span></span><span>
Simplify: </span><span><span><span>5x</span>−9</span>=<span><span>5x</span>−9</span></span>
Step 2: Subtract 5x from both sides.<span><span><span><span>5x</span>−9</span>−<span>5x</span></span>=<span><span><span>5x</span>−9</span>−<span>5x</span></span></span><span><span>−9</span>=<span>−9</span></span>
Step 3: Add 9 to both sides.<span><span><span>−9</span>+9</span>=<span><span>−9</span>+9</span></span><span>0=0</span>Answer:<span>All real numbers are solutions.</span>

Answer: 1 .Thus for a graph to have an Euler circuit, all vertices must have even degree. The converse is also true: if all the vertices of a graph have even degree, then the graph has an Euler circuit, and if there are exactly two vertices with odd degree, the graph has an Euler path.

2. A graph has an Euler circuit if and only if the degree of every vertex is even. A graph has an Euler path if and only if there are at most two vertices with odd degree.

Step-by-step explanation:

Use the Law of Sines to find the measure of angle J to the nearest degree.
rjkz [21]
\bf \textit{Law of sines}&#10;\\ \quad \\&#10;\cfrac{sin(\measuredangle A)}{a}=\cfrac{sin(\measuredangle B)}{b}=\cfrac{sin(\measuredangle C)}{c}\\\\&#10;-----------------------------\\\\&#10;\cfrac{sin(J)}{9.1}=\cfrac{sin(97^o)}{11}\implies sin(J)=\cfrac{9.1\cdot sin(97^o)}{11}&#10;\\\\\\&#10;\textit{now taking }sin^{-1}\textit{ to both sides}&#10;\\\\\\&#10;sin^{-1}\left[ sin(J) \right]=sin^{-1}\left( \cfrac{9.1\cdot sin(97^o)}{11} \right)&#10;\\\\\\&#10;\measuredangle J=sin^{-1}\left( \cfrac{9.1\cdot sin(97^o)}{11} \right)
