Question

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

Answer 1

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

Answer 2

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

Explanation:

Equation :
`5(x+2)\geq (7x+2(x-1)`

`5x+10 \geq 7x+2x-2`

`12 \geq 4x`

Divide by 4 both sides

`3 \geq x`

So,
`x\leq 3`

So, Therefore, the solution set is:

(-∞, 3]

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