Answer:

Step-by-step explanation:

12(x-2)+3x = \frac{1}{2}(x+6)+2\\\\12*x-12*2+3x=\frac{1}{2}x+\frac{1}{2}*6+2\\\\12x - 24+3x =\frac{1}{2}x+1*3+2\\\\15x - 24 = \frac{1}{2}x+3+2\\\\15x-24=\frac{1}{2}x+5\\\\15x-\frac{1}{2}x-24=5\\\\\frac{15*2}{1*2}x-\frac{1}{2}x=5+24\\\\\frac{30}{2}x-\frac{1}{2}x=29\\\\\frac{29}{2}x=29\\\\x=29*\frac{2}{29}\\\\x=2

PLZ HELP WILL GIVE BRAINLIEST 50+25 POINTS!!!<br><br>Graph the following piecewise function.
Luda [366]

We need to graph the given piecewise function.

To graph any piecewise function we do that into parts

Let's graph upper part first which is

f(x)=x^2+2

restriction for that is -5 \leq x < 3

that means we are free to pick any number for x that is between -5 and 3, including 3.

So we will find few points by plugging random numbers between -5 and 3.

Let's use x=-5, we get:

f(-5)=(-5)^2+2=25+2=27

so first point is (-5,27).

similarly we can find other points like (0,2), (2,6), (-1,3) etc.

Now we join those points by a curved line.

-5 \leq x means we use a close circle at -5

x<3 means use open circle at 3


------------

Repeat same process for 2nd part f(x)=x-4

choose any number between 3 and 7 like x=3, 4 etc

so we get points (3,-1), (4,0) etc

Now graph them

So the final graph will look like:
