Which are correct representations of the inequality 6x ≥ 3 + 4(2x – 1)? Check all that apply.

telo118 [61]

Answer:

Both

1 ≥ 2x

and

6x ≥ 3 + 8x – 4

Step-by-step explanation:

Correct representations are representations which are equivalent and represent the exact same relationship. To find these, you can simplify the inequality.

6x ≥ 3 + 4(2x – 1)

6x ≥ 3 + 8x - 4

6x ≥ 8x - 1

-2x ≥ -1

2x ≤ 1

x ≤ 1/2

Can someone help me find the inverse of this? Please show steps. :(<img src="https://tex.z-dn.net/?f=f%28x%29%3D%20%5Cfrac%7B1%7

miss Akunina [59]

$\frac{1}{9}( 3^{x}) = 3 ^ {x-2}$
So the inverse is
$(log _{3} {x}) + 2$
