Answer:

Second option: $3 + 4 x\leq 2 (1 + 2x)$

Step-by-step explanation:

Let's solve for "x" from each inequality:

$a.\ 6 (x + 2)>x-3\\\\6x+12>x-3\\\\6x-x>-3-12\\\\5x>-15\\\\x>\frac{-15}{5}\\\\x>-3$

$b.\ 3 + 4 x\leq 2 (1 + 2x)\\\\3+4x\leq 2+4x\\\\3-2\leq 4x-4x\\\\1\leq 0\ (FALSE.\ IT\ HAS\ NO\ SOLUTION)$

$c.\ -2 (x + 6)$

$d.\ x-9$

Simplify. 3^2+ (9-8/2)

solmaris [256]

Hi there! Hopefully this helps!

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

Answer: 14.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

First we calculate 3 to the power of 2 and get 9.

9 + 9 - $\frac{8}{2}$ = 14.

Now we add 9 + 9 to get 18.

18 - $\frac{8}{2}$ = 14.

Then, we divide 8 by 2 to get 4.

18 - 4 = 14.

Then we subtract 4 from 18 to get.....You guessed it, 14!

Also, since you multiplied a negative and a positive, your final answer will be negative.

X= 6
Y= 0
Z= -2

CHECK
3x + y -2z =22
3(6) + 0 -2(-2) =22
18 + 0 +4= 22
22=22

x+5y+z =4
6 +5(0)+ -2 =4
6 + 0 +-2 = 4
4=4

x+3z=0
6 + 3(-2) =0
6 -6 = 0
0=0
