Answer 1
Answer:

Answer:

19/9

Step-by-step explanation:

x=2.1 repeating

10x=21.1 repeating

PLEASE HELP!!!!Solve the compound inequality for x and identify the graph of its solution.
4xs-16 or 3x + 5 2 17

Answers

The solution of the compound inequality 4x ≤ -16 or 3x + 5 ≥ 17 is x ≤ -4 or x ≥ 4 and graphed in option (B).

What is inequality?

Essentially, comparing any two values shows whether one is smaller, greater, or equal to the value on the other side of the equation. Essentially, comparing any two values shows whether one is smaller, greater, or equal to the value on the other side of the equation.

Given the first inequality,

4x ≤ -16

Dividing 4 both sides

x ≤ -4

Second inequality,

3x + 5 ≥ 17

Subtract 5 on both sides

3x ≥ 12

Divide 3 both side

x ≥ 4

So,

x ≤ -4 or x ≥ 4

Hence "The solution of the compound inequality 4x ≤ -16 or 3x + 5 ≥ 17 is x ≤ -4 or x ≥ 4".

i think combine like terms  
12x+10x+3x+2x      -y+y+5y
X=27                       Y=5y
any two opposite angles are equal so, 
12x - y = 10x +5y 
12x-10x = 5y+y 
2x = 6y 
so x=3y ----> eqn.1 

and, the sum of all angles are equal 360 degrees 
so 12x-y + 2x+4y + 10x+ 5 y + 3x + y = 360 then , 27x + 9y = 360  substitute by y= x/3 from eqn.1 the 27x +9(x/3) = 360 27x+3x=36030x=360x=12 substitute in eqn.1 y=x/3 y=12/3y=4 so  we get x = 12 & y = 4
