Which is the solution set to the inequality (4x-3)(2x-1)>0?

Lapatulllka [165]

Set each factor equal to 0
4x-3 = 0
2x-1 = 0

Solve for x.
4x-3=0
4x=3
x= 3/4

Solve for x.
2x-1= 0
2x= 1
x= 1/2

Eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

-2(w+4)+9< minus 11 plz help

Anestetic [448]

For this case we must resolve the following inequality:

$-2 (w + 4) +9$

We apply distributive property to the terms within parentheses:

$-2w-8 + 9$

We add similar terms from the left side of the equation:

$-2w + 1$

We subtract 1 from both sides of the inequality:

$-2w$

We divide between -2 on both sides taking into account that the sense of inequality changes:

$w> \frac {-12} {- 2}\\w> 6$

Answer:

$w> 6$
