Answer:

solution for the given inequality: (-\infty, -4)

Step-by-step explanation:

Given that: \frac{x+4}{2x-1}

Multiplying both sides by 2x-1 we get;

x+4< 0

Subtract 4 from both sides we get;'

x+4-4< 0-4

Simplify:

x< -4

Therefore, the solution for the given inequality: (-\infty, -4)

Given the function f(x) = 4x - 2, explain and show how to find the average rate of change between x = 2 and x = 4.
zalisa [80]

Answer:

The average rate of change between x = 2 and x = 4 is of 4.

Step-by-step explanation:

Average rate of change:

The average rate of change of a function f(x) in an interval [a,b] is given by:

A = \frac{f(b)-f(a)}{b-a}

In this question:

f(x) = 4x - 2, b = 4, a = 2

Thus:

f(b) = f(4) = 4(4) - 2 = 16 - 2 = 14

f(a) = f(2) = 4(2) - 2 = 8 - 2 = 6

Average rate of change:

A = \frac{f(b)-f(a)}{b-a}

A = \frac{14-6}{4-2}

A = \frac{8}{2}

A = 4

The average rate of change between x = 2 and x = 4 is of 4.

Which value of x is in the solution set of the following inequality -3×+5&gt;17
Sholpan [36]

Answer:

x < -4

Step-by-step explanation:

To solve the inequality, use inverse operations.

-3x + 5 > 17

-3x > 17 - 5                    Subtract 5 from both sides.

-3x > 12                         Divide both sides by -3.

x < -4                             Flip the inequality sign since you divided by a negative.

Hoochie [10]

Solution :

Given :

National mean score of the reading test that is conducted the NAEP = 288

Standard deviation of the score = 38

Therefore, P(X > x) = 0.25

P (Z > $\frac{x-288}{38} $ = 0.674)

$\frac{x-288}{38} = 0.674$

$x=288+(38 \times 0.674)$

x = 326.67

Therefore, the highest score that is needed for the students to be in the top of 25 percent among the students those who take the exam.
