Answer: \frac{1}{2} + \frac{4}{2} x =x + \frac{4}{10}

\frac{1}{2} +2x=x+ \frac{2}{5}

subtract x from each side

\frac{1}{2} + x= \frac{2}{5}

now subtract \frac{1}{2} from each side

x= -0.1

Step-by-step explanation:

\frac{1}{2} + \frac{4}{2}x =x + \frac{4}{10}
\frac{1}{2} +2x=x+\frac{2}{5}
subtract x from each side
\frac{1}{2} + x=\frac{2}{5}
now subtract \frac{1}{2} from each side 
x= -0.1

Montano1993 [528]

Nick has tennis practice every sixth day = 6

Mark has tennis practice every 4th day = 4

They both had tennis practice on = 31st July

We have to find when will be the next time that they both have practice on the same day?

For this, we will find the LCM of 4 and 6

So, LCM of 4 and 6 is 12.

So, it will be 12 days after 31st July, that they will practice on the same day.

So it is 12th August.

Can anyone explain how to do this? I looked at the book and now I'm even more confused. 50 points
katrin [286]

The piecewise function is basically the result of two different functions combined together. If x is 0 or larger, then h(x) = x+4. Otherwise, if x < 0, then h(x) = -x-4

No matter what number you pick for x, the h(x) function will be used in some way. So the domain is the set of all real numbers. To write this in interval notation, we write (-\infty, \infty) which means we start off at negative infinity and go to positive infinity. This is basically saying "the entire real number line". Since we can't actually reach either infinity, we always use parenthesis with them. <u>Never</u> use square brackets with either infinity

From the graph (see attached image below), we see that (0,-4) is the lowest point. This means y = -4 is the smallest y output possible, though we can't actually reach it because of the open circle at (0,-4). We can get any other larger y value. So the range is therefore: (-4, \infty) meaning we start at -4 and head off to positive infinity. The curve parenthesis next to -4 the reader "exclude -4 as part of the range". There is an open hole or gap here. Another way to state the range is to write y > -4
