Answer: [tex]x=\frac{1}{3}[/tex]

Step-by-step explanation:

You need to remember the Negative exponent rule:

[tex]a^{-n}=\frac{1}{a^n}[/tex]

Then, having the equation [tex]9x^{-1} - 2 = 25[/tex], you can rewrite it in this form:

[tex]\frac{9}{x} - 2 = 25[/tex]

Now add 2 to both sides of the equation:

[tex]\frac{9}{x} - 2+2 = 25+2\\\\\frac{9}{x}=27[/tex]

Multiply both sides of the equation by "x":

[tex](x)(\frac{9}{x})=27(x)\\\\9=27x[/tex]

 And finally divide both sides of the equation by 27.

The value of "x" is:

[tex]x=\frac{9}{27}\\\\x=\frac{1}{3}[/tex]

Answer:

C on edg

Step-by-step explanation:

For this case we must simplify the given expression:

Rewriting we have:

[tex]\sqrt [3] {\frac {2 * 5x ^ 5} {2 * 27x ^ 8}} =\\\sqrt [3] {\frac {5x ^ 5} {27x ^ 8}} =[/tex]

By definition of division of powers of equal base, the same base is placed and the exponents are subtracted:

[tex]\sqrt [3] {\frac {5x ^ {5-8}} {27}} =\\\sqrt [3] {\frac {5x ^ {- 3}} {27}} =\\\sqrt [3] {\frac {5} {27x ^ 3}} =[/tex]

We have to:

[tex]\sqrt [3] {27x ^ 3} = 3x[/tex]

Then, the expression is reduced to:

[tex]\frac {\sqrt [3] {5}} {3x}[/tex]

Option D

Answer:

its D jus trust

Step-by-step explanation:

For this case we must find the inverse of the following function:

[tex]f (x) = 4x + 7[/tex]

For it:

Replace f (x) with y:

[tex]y = 4x + 7[/tex]

We exchange the variables:

[tex]x = 4y + 7[/tex]

We solve for y:

We subtract 7 on both sides of the equation:

[tex]x-7 = 4y[/tex]

We divide between 4 on both sides of the equation:

[tex]y = \frac {x} {4} - \frac {7} {4}[/tex]

Finally, we change y by[tex]f ^ {- 1} (x)[/tex]:

[tex]f ^ {- 1} (x) = \frac {x} {4} - \frac {7} {4}[/tex]

ANswer:

[tex]f ^ {- 1} (x) = \frac {x} {4} - \frac {7} {4}[/tex]

the inverse function f-1(x) is (x - 7) / 4, which matches option B: f-1(x) = (x / 4) - (7 / 4).

The student asks which of the provided options is the inverse of the function f(x) = 4x + 7. To find the inverse function, we usually swap x and y and then solve for y. The steps to find the inverse are:

Therefore, the inverse function f-1(x) is (x - 7) / 4, which matches option B: f-1(x) = (x / 4) - (7 / 4).

Answer:

The probability of drawing three queens is 1/425

Step-by-step explanation:

* lets talk about the deck cards

- The deck cards has 52 cards

- It has four symbols (heart , diamond , clubs , spades)

- Each symbol has 16 cards (from 1 to 10 and king , queen , princess)

* Lets solve the problem

- We will drawing three cards

- The cards are not replaced

- That means the total of the card will reduce by 1 after each drawing

- The cards will drawing are queens

- The first card drawn will be a queen

∵ The first card drawn is queen

∴ The number of cards for the second drawn is 52 - 1 = 51

∵ There are 4 queens in the deck cards we took one for the first choice

∴ The number of queen for the second choice is 4 - 1 = 3

∴ The probability of second choice is 3/51

- Now there are 2 queens and 50 cards after the second choice

∴ The number of the queen is 3 - 1 = 2

∴ The number of the deck cards is 51 - 1 = 50

∴ The probability of third choice is 2/50

- The probability of the three cards is the product of the two fractions

∴ The probability of drawing three queens = 3/51 × 2/50 = 6/2550

- Simplify the fraction

* The probability of drawing three queens = 1/425

Answer:

y = 6x - 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, - 4) and (x₂, y₂ ) = (1, 2)

m = [tex]\frac{2+4}{1-0}[/tex] = 6

note the line crosses the y- axis at (0, - 4) ⇒ c = - 4

Answer:

y + 0.5 = 3(x - 2).

Step-by-step explanation:

We use the point-slope form of the equation which is y - y1 = m(x - x1).

Here m = 3 , x1 = 2 and y1 = -0.5, so the equation is:

y - (-0.5) = 3(x - 2)

y + 0.5 = 3(x - 2).

Answer:

∠1 = ∠4 and ∠3 = ∠5  ( alternate interior angle).

Step-by-step explanation:

Given : Triangle ABC with angle  1, 2, 3.

To find : Complete the statements to prove that the sum of the interior angles of ΔABC is 180°.

Solution : We have given that triangle ABC with angle  1, 2, 3.

Here, line DE and AC are parallel and BA is traversal line.

∠1 = ∠4 ( alternate interior angle)

∠3 = ∠5 ( alternate interior angle)

∠4 + ∠2+ ∠5 = 180  ( angle formed on line)

∠1 + ∠2 + ∠3 = 180.

Therefore, ∠1 = ∠4 and ∠3 = ∠5  ( alternate interior angle).

The angles in a triangle add up to 180 degrees.

The text that completes the proof is: alternate interior angle

From the question, we can see that the missing statement is on the 4th line

Where:

[tex]\angle 1 \cong \angle 4[/tex] and [tex]\angle 3 \cong \angle 5[/tex]

From the figure of the triangle, we can see that:

Hence, the statement that completes the proof is: alternate interior angle

Answer:

The third option, or 9, is the answer.

Step-by-step explanation:

The length of the apothem can be found using the pythagorean theorem. Since the length of each side of the hexagon is 10, the base of the triangle is 5, since 10/2=5. Plugging these two values into the pythagorean equation leaves 25+b^2=100.

B^2 = 75, so the length of the apothem is sqrt(75)

this is approximately 8.66, so the answer is 9.

The length of the apothem is 9 inch.

The apothem of a regular polygon is a line segment from the center to the midpoint of one of its sides.

Using the pythagoras theorem.

As, the length of each side of the hexagon is 10.

so, the base of the triangle is 10/2=5.

Now using two values we get

25+b²=100.

B² = 75

Hence, so the length of the apothem is √75 = 8.66 = 9 (approx)

Answer:

The angle made by line with positive x axis is more than 90°

Step-by-step explanation:

A line is represented in slope intercept form as

y=mx+c

Where m is called the slope of the line and c is called the y intercept .

Here by slope we means the tangent of the angle , the line makes with the positive x axis .

Now in the case when the coefficient of x is negative , that means the tangent of the angle which line makes with the positive direction of x axis is negative

or

tan [tex]\theta[/tex] = negative

[tex]\theta[/tex] > 90

that means our line makes an obtuse angle that is more than 90° with the positive x axis.

Answer:

"the original amount of the loan"

Step-by-step explanation:

x value would be the time in months and y value would be the loan amount that is left.

The y-intercept is basically the point where x is 0. So, we can say the y-intercept would be when time is 0.

That's basically when the loan started and the y-value represents the full loan amount., which is $22,000.

The correct answer is third option -- "the original amount of the loan".

Answer:

The correct option is C.

Step-by-step explanation:

It is given that a scatter plot is made to model the amount of money left to pay on a car loan.

From the given table we can conclude that the number or months represented by variable x and the amount of money owed is represented by variable y.

At y-intercept the value of x is 0. It means the y-intercept represents the amount of money owed when the number of months is 0.

In other words, the y-intercept of the model represents the original amount of loan.

Therefore the correct option is C.

Answer:

independent equations

Choice C is correct

Step-by-step explanation:

The system of linear equations that contains the equations;

Y = 1/2 X +2 and y =-3X +2 is said to be consistent since it has at least one solution;

The point (0,2)

If a consistent system of equations has exactly one solution, it is said to be independent.

Final answer:

The correct term describing a set of equations where each equation represents a different line that intersects at only one point is 'independent equations'.

Explanation:

The point (0,2) is mentioned as the only solution to the system of linear equations with equations y = 1/2x + 2 and y = -3x + 2. Since both equations have only one point of intersection, this means that the graphs of the two equations are two different lines that intersect at exactly one point. This means the system is consistent and the equations are independent, as they form two different lines.

Therefore, the term that describes a set of equations where each equation represents a straight line and they intersect at exactly one point is independent equations.
