                Hi my lil bunny!

❧⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯☙

Lets do this step by step.

Simplify \frac{3x - 2}{x} -4.

To write -4 as a fraction with a common denominator, multiply by \frac{x}{x}

\frac{3x - 2}{x} - 4 . \frac{x}{x} > 0

Combine  -4 and \frac{x}{x}.

\frac{3x - 2}{x} + \frac{-4x}{x} > 0

Combine the numerators over the common denominator.

\frac{3x - 2 -4x}{x} > 0

Subtract 4x from 3x.

\frac{-x -2}{x} > 0

Factor -1 out of -x.

\frac{-(-x) -2}{x} >0

Rewirte -2 as -1 (2).

\frac{-(x -1 (2)}{x} > 0

Factor -1 out of - (x) - 1 (2).

\frac{-(x + 2)}{x} >0

Simplify the Expression.

_______________

Rewrite - ( x + 2 ) as -1 ( x + 2 ) .

\frac{-1 ( x+ 2)}{x} > 0

Move the negative in front of the fraction.

- \frac{x + 2}{x} > 0

Then your going to find all the values where the expression switches from negative to positive by setting each factor equal to 0  and solving.

x = 0\\x + 2 = 0

Subtract 2 from both sides of the equation.

x = -2

Solve for each factor to find the values where the absolute value expression goes from negative to positive.

x = 0 \\x = -2

Consolidate the solutions.

x = 0, -2

________________

Find the domain of \frac{3x - 2}{x} -4

_________________

Set the denominator in \frac{3x - 2}{x}  equal to 0 to find where the expression is undefined.

x = 0

The domain is all values of x that make the expression defined.

( - ∞, 0 ) ∪ ( 0 , ∞)

Use each root to create test intervals.

x < -2 \\-2 < x < 0 \\x > 0

|Choose a test value from each interval and plug this value into the original inequality to determine which intervals satisfy the inequality.|

Test a value on the interval -2 < x < 0 to see if it makes the inequality true.

Ans : True

Test a value on the interval x > 0 to see if it makes the inequality true.

Ans : False

Test a value on the interval x < -2  to see if it makes the inequality true.

Ans : False

Compare the intervals to determine which ones satisfy the original inequality.

x < -2 = False\\-2 < x < 0 = True\\x > 0 = False

The solution consists of all of the true intervals.

-2 < x < 0

The result can be shown in multiple forms.

Inequality Form: -2  < x< 0

Interval Notation: ( -2 , 0 )

What is 25% of 400 5% of 20
stiks02 [169]

Hello there!


What is 25% of 400?

\frac{25*400}{100}

= \frac{10,000}{100}

= 100

Thus,

25% of 400 is 100


What is 5% of 20?

Well, we just need to follow the previous steps.

\frac{5*20}{100}

= \frac{100}{100} = 1

Thus,

5% of 20 is 1


I hope this answer helps. Let me know if you have additional questions about the answer. As always, it is my pleasure helping student like you.

If s(x) = x – 7 and t(x) = 4x2 – x + 3, which expression is equivalent to
Vlada [557]
The answer is If you would like to find the expression that is equivalent to (t*s)(x), you can calculate this using the following steps:

s(x) = x - 7
t(x) = 4x^2 - x + 3

(t*s)(x) = t(s(x)) = t(x - 7) = <span>4(x - 7)^2 - (x - 7) + 3 = 4(x - 7)^2 - x + 7 + 3

The correct result would be </span>4(x – 7)2 – (x – 7) + 3.

Given the original number n. Multiply the number by 9. Add 99. Divide this sum by 9. Subtract the original number, n, from the q
tangare [24]

Answer:

11

Step-by-step explanation:

Hello,

Given the original number n.

\large \boxed{n}

Multiply the number by 9.

\large \boxed{9n}

Add 99.

\large \boxed{9n+99}

Divide this sum by 9.

\large \boxed{\dfrac{9n+99}{9}=n+11}

Subtract the original number, n, from the quotient.

\large \boxed{n+11-n=11}

Thank you.
