Which of following not a way to represent the solution of inequality 5(x + 2) GREATER THAN OR EQUAL TO 7x + 2(x − 1)?
(A )A number line with a closed circle on 3 and shading to the right
(B) A number line with a closed circle on 3 and shading to the left
(C) 3 greater than or equal to x
(D) x less than or equal to 3

Respuesta :

So because it says NOT a way....I think it's A...Maybe I'm wrong but whatever.

Answer:

A number line with a closed circle on 3 and shading to the left

Step-by-step explanation:

Equation : [tex]5(x+2)\geq (7x+2(x-1)[/tex]

[tex]5x+10 \geq 7x+2x-2[/tex]

[tex]12 \geq 4x[/tex]

Divide by 4 both sides

[tex] 3 \geq x[/tex]

So, [tex]x\leq 3[/tex]

So, Therefore, the solution set is:

(-∞, 3]

So,  A number line with a closed circle on 3 and shading to the left
