Step-by-step explanation:

| x - 2 | < 4

Start at x=2.  Go 4 units in either direction: x=-2 and x=6.  Draw empty circles around each.  Since it's less than, the line goes between the circles, connecting them.  The result should look like this:

| x + 2 | > 4

Start at x=-2.  Go 4 units in either direction: x=-6 and x=2.  Draw empty circles around each.  Since it's greater than, the line goes outside of the circles.  The result should look like this:

Answer:

Step-by-step explanation:

3.

|x-2|<4

-4<x+2<4

subtract 2 from each inequality

-4-2<x+2-2<4-2

-6<x<2

4.

|x+2|>4

x+2<-4 and x+2>4

or x+2-2<-4-2 and x+2-2>4-2

or x<-6 and x>2

A chemist wants to make 100 liters of a 44% acid solution. She has solutions that are 20% acid and 60% acid.
alexgriva [62]

the first solution is 20% acid, and say we'll be using "x" liters, so how many liters of just acid are in it?  well 20% of "x" or namely 0.2x.  Likewise for the 60% acid solution, if we had "y" liters of it, the amount of only acid in it is 0.6y.

\begin{array}{lcccl} &\stackrel{solution}{quantity}&\stackrel{\textit{\% of }}{amount}&\stackrel{\textit{liters of }}{amount}\\ \cline{2-4}&\\ \textit{1st solution}&x&0.20&0.2x\\ \textit{2nd solution}&y&0.60&0.6y\\ \cline{2-4}&\\ mixture&100&0.44&44 \end{array}~\hfill \begin{cases} x+y=100\\\\ 0.2x+0.6y=44 \end{cases}

x+y=100\implies y=100-x~\hfill \stackrel{\textit{substituting on the 2nd equation}}{0.2x+0.6(100-x)=44} \\\\\\ 0.2x+60-0.6x=44\implies -0.4x+60=44\implies -0.4x=-16 \\\\\\ x=\cfrac{-16}{-0.4}\implies \boxed{x=40}~\hfill \boxed{\stackrel{100-40}{y=60}}
