Solve this system of linear inequalities ( will give brainiest)
lakkis [162]
From the graphs you can see that the graph of the line y= \frac{1}{3} x-3 lies under the graph of the line y= \frac{1}{3} x-1. Then all solutions of unequality y\le \frac{1}{3} x-3 are solutions of unequality y\le \frac{1}{3} x-1, but not all solutions of unequality y\le \frac{1}{3} x-1 are solutions of unequality y\le \frac{1}{3} x-3. 
For example, if x=1, y=-2
-2\le  \frac{1}{3} \cdot 1-1 =- \frac{2}{3} \\ -2\ \textgreater \  \frac{1}{3} \cdot 1-3=- \frac{8}{3}.
Answer: Correct choice is B.

2) -2(7n – 6) +n=-3 - 8n
iogann1982 [59]

<em>Answer and Step-by-step explanation:</em>

<em>For this equation the answer is : n=3</em>

<em>Step 1 : Simplify both the sides of the equation :</em>

<em>-2(7n-6)+n=-3-8n</em>

<em>(-2)(7n)+(-2)(-6)+n=-3+-8n   (Distribute)</em>

<em>-14n+12+n=-3+-8n</em>

<em>(-14n+n)+(12)=-8n-3   (Combine the like terms)</em>

<em>-13n+12=-8n-3</em>

<em>-13n+12=-8n-3</em>

<em>Step 2 : Add "8n" to both the sides :</em>

<em>-13n+12+8n=-8n-3+8n</em>

<em>-5n+12=-3</em>

<em>Step 3 : Subtract "12" from both the sides :</em>

<em>-5n+12-12=-3-12</em>

<em>-5n=-15</em>

<em>Step 4 : Divide both the sides by "-5"</em>

<em>\frac{-5n}{-5} =\frac{-15}{-5}</em>

<em>n=3</em>

<em />

<em>That's your final answer : n=3</em>
