The value of x = -5/2

To solve this question we must understand the concept of indices.

<h3>What are Indices?</h3>

Indices in mathematics show the power to which an expression or variable is raised.

Here, the correct format of the equation given in the question as follows:

\mathbf{2 \sqrt[3]{3x +2}} \mathbf{= \sqrt[3]{4x -9} }

2(3x+2)^{1/3} = (4x -9)^{1/3} \\ \\ (6x + 4)^{1/3} =(4x -9)^{1/3}

Multiply the power of both sides by 3

(6x + 4) =(4x -9)

6x - 4x = -9 + 4      

2x = -5

x = -5/2

What is the slope of this line?
Brums [2.3K]

Answer:

slope=\frac{1}{4}

Step-by-step explanation:

The slope of a line can be seen as:

\frac{rise}{run}

Rise over run is the change in the y values over the change in x values. For example, in this graph, you would start on one of the points given. From there, you would move up first. After moving up a certain number of spaces, you would move to the side until you reach the other point.

In the graph, you would move up until you are in line with one of the other points. Starting at (-4,5), move up one space, then to the left 4 spaces to reach the point (0,6). Using the spaces moved in the rise over run:

\frac{1}{4} =\frac{rise}{run}=slope

Therefore, the slope is \frac{1}{4}.

This is true for any two points on the line.

:Done

*When you move up, the number will be positive (\frac{+y}{x} ). If you move down, the number will be negative (\frac{-y}{x} ). If you move left, the number will be positive (\frac{y}{+x}). If you move right, the number will be negative (\frac{y}{-x} ). Keep this in mind. It is very important.

**Always <em>move along the y-axis first</em>, then move along the x-axis. If you do it the other way, the slope will be wrong.

Write the area as a product:<br> 3x^2 - 7x - 6
bulgar [2K]

Answer:

product is a ⋅ c = 3 ⋅ − 6 = − 18 and whose sum is b = − 7 .

Step-by-step explanation:

Factor

− 7 out of − 7 x .

3 x 2 − 7 ( x ) − 6

Rewrite

−7 as 2 plus −9

3 x 2 + (2−9) x −6

Apply the distributive property.

3 x 2 + 2 x − 9 x − 6

Explain how you can find 4 times 754 using two different methods
ANEK [815]
Method 1:

4(754)

=4(700+50+4)

=2800 + 200 + 16

=3000+16

=3016

-----------------

Method 2:

4(754)

=4(250+250+250+4)

=1000+1000+1000+16

Write the expression in terms of sine and cosine and simplify so that no quotients appear in the final expression. Show work.
AlexFokin [52]
<h3>Answer:</h3>

sec²(x)

<h3>Explanation:</h3>

As required:

... = (sin²(x)/cos²(x))(1 +(cos²(x)/sin²(x))

... = (sin²(x)·(sin²(x)+cos²(x)) / (cos²(x)·sin²(x))

... = 1/cos²(x) = sec²(x)

_____

Alternatively, multiply out the given expression, then use trig identities.

... = tan²(x) + (tan(x)·cot(x))² = tan²(x) +1 = sec²(x)
