Answer:

Exact Form:  x = 1 /4

Decimal Form:  x = 0.25

Step-by-step explanation:

Solve for  x  by simplifying both sides of the equation, then isolating the variable.

Himpunan penyelesaian pertidaksamaan nilai mutlak |2x-4| > |3x+2|
Stells [14]

Answer:

The solution in interval notation is:

(-6,\frac{2}{5}).

The solution in inequality notation is:

-6.

Step-by-step explanation:

I think you are asking how to solve this for x.

Keep in mind |x|=\sqrt{x^2}.

|2x-4|>|3x+2|

\sqrt{(2x-4)^2}>\sqrt{(3x+2)^2}

If \sqrt{u}>\sqrt{v} then u>v.

(2x-4)^2>(3x+2)^2

Subtract (2x-4)^2 on both sides:

0>(3x+2)^2-(2x-4)^2

Factor the difference of squares a^2-b^2=(a-b)(a+b):

0>((3x+2)-(2x-4))((3x+2)+(2x-4))

Simplify inside the factors:

0>(x+6)(5x-2)

(x+6)(5x-2)

The left hand side is a parabola that faces up.  I know this because the degree is 2.  

The zeros of the the parabola are at x=-6 and x=2/5.

We can solve x+6=0 and 5x-2=0 to reach that conclusion.

x+6=0

Subtract 6 on both sides:

x=-6

5x-2=0

Add 2 on both sides:

5x=2

Divide both sides by 5:

x=2/5

Since the parabola faces us and (x+6)(5x-2) then we are looking at the interval from x=-6 to x=2/5 as our solution.  That part is where the parabola is below the x-axis.  We are looking for where it is below since it says the where is the parabola<0.

The solution in interval notation is:

(-6,\frac{2}{5}).

The solution in inequality notation is:

-6.

You are choosing numbers from the set S ={A, B, C, D, E, F, G, H}. Let x = the number of ways to choose 3 letters from S without
worty [1.4K]

The equivalent of x is (a) the number of ways to choose 5 letters from S without replacement

<h3>How to determine the equivalent of x?</h3>

The set is given as:

S ={A, B, C, D, E, F, G, H}

The above set has 8 elements.

To select 3 elements from S, we use the following parameters:

n = 8

r = 3

And the number of ways is:

Ways = ^8C_3

As a general rule, the above expression is equivalent to

Ways = ^8C_{8-3}

Evaluate

Ways = ^8C_{5

This means that the number of ways to select 3 elements is equivalent to selecting 5 elements

Hence, the equivalent of x is (a)
