the correct question is
Part A: Explain why the x-coordinates of the points where the graphs of the equations y = 4−x and y = 8-x^-1 intersect are the solutions of the equation 4−x = 8-x^-1.
Part B: Make tables to find the solution to 4−x = 8-x^-1. Take the integer values of x between −3 and 3. 
Part C: How can you solve the equation 4−x = 8-x^-1 graphically?

Part A.  We have two equations:  y = 4-x   and   y = 8-x^-1
Given two simultaneous equations that are both to be true, then the solution is the points where the lines cross. The intersection is where the two equations are equal. Therefore the solution that works for both equations is when
4-x = 8-x^-1
This is where the two graphs will cross and that is the common point that satisfies both equations.

Part B

The length of a rectangle is increasing at a rate of 3 cm/s and its width is increasing at a rate of 5 cm/s. when the length is 14 cm and the width is 9 cm, how fast is the area of the rectangle increasing?

Answers

area of rectangle = L * W

Differentiate with respect to time:

 dA
----- = L*(dW/dt) + W*(dL/dt)
 dt

Here, 

 dA
----- = (14 cm)*(5 cm/sec) + (9 cm)*(3 cm/sec)
 dt

Finish the indicated multiplication and addition to obtain your final answer.

The area of the rectangle at L = 14 cm and B = 9 cm is increasing at 97 cm²/s.

What is the area of rectangle?

The area of a rectangle is given by -

A[R] = L x B

Given is the length of a rectangle is increasing at a rate of 3 cm/s and its width is increasing at a rate of 5 cm/s.

Now, we can write -

dL/dt = 3 cm/s

dB/dt = 5 cm/s

We know, that the area is -

A = LB

differentiating both sides with respect to [t], we get -

dA/dt = L dB/dt + B dL/dt

dA/dt = 5L + 3B

At L = 14 cm and B = 9 cm.

(dA/dt) [14, 9] = 5 x 14 + 3 x 9 = 70 + 27 = 97 cm²/s

Therefore, the area of the rectangle at L = 14 cm and B = 9 cm is increasing at 97 cm²/s.

The cost function for kara's new clothing store where she sells t-shirts is c = $9.90n + 1060. what is the slope of the cost function for kara's new store?

Answers

Remember that in a linear function of the form [tex]y=mx+b[/tex], the slope, [tex]m[/tex], is the coefficient of the independent variable [tex]x[/tex].

In our cost function [tex]c=9.90n+1060[/tex], [tex]y=c[/tex] and [tex]x=n[/tex], so we can infer that the independent variable is [tex]n[/tex]. Since the coefficient of [tex]n[/tex] is 9.90, the slope of the cost function is 9.90.

We can conclude that the slope of Kara's new store cost function is $9.90

Answer:

The slope of the function is 9.90

Step-by-step explanation:

You can find the slope by looking at the coefficient of the independent variable in the equation. In this case, we would be looking for the coefficient of n.

How do you solve this problem?

Answers

Very nice problem. You should look up the history of this question. It has a very long one having to do with mirrors made between 50 BC and 50 AD.

Step One
Find AB, BC, AC
Before beginning this problem, I'm going to arbitrarily name 
c = AB
a = BC
b = AC It just makes the calculations easier.

AB = radius of the large circle - radius of the medium circle = 20.62 - 8.04 = 12.58
BC = Radii of the two smaller circles added together = 8.04 + 7.35 = 15.39
AC = Radius of the large circle - Radius of the small circle = 20.62 - 7.35 = 13.27

So
a = 15.39
b = 13.27
c = 12.58

Step Two
Find Angle A or <BAC
a^2 = b^2 + c^2 - 2*b*c * Cos(A)
15.39^2 = 12.58^2 + 13.27^2 - 2 * 12.58 * 13.27 * Cos(A)
236.852 = 158.26 + 176.1 -  333.87 * Cos(A)
236.852 = 334.4 - 333.87*Cos(A)
-97.55 = - 333.87 *  Cos(A) 
-97.55 / -333.87 = Cos(A)
0.2922 = cos(A)
A = cos-1(0.2922)
A = 73.01 degrees

Step Three
Just to see if you understand what was done, I'll give you the givens for finding c, and the answer and you can work through the calculations to see if your answer agrees with mine. If it doesn't PM me.
c = 12.58
b = 13.27
a = 15.39

12.58^2 = 13.27^2 + 15.39^2 - 2*13.27*15.39*Cos(C)
C = 51.42

Step Four
Find <B
Every triangle has 180 degrees so
B = 180 - <A - C
B = 180 - 51.42 - 74.01
B = <54.57. 
I have found a moderator who opened the question up so that I can show you why the Cos law is the only way to do this. If the circles are very disproportionate as in this diagram, then no simple assumption can be made. The cos law is all that will work.

The point is how to remove the brackets when a minus sign is on the left hand side. A second problem is how to get all the terms on one side over to the other.

Step One
Remove the brackets on the left side. This is an absolutely necessary step in the rest of your mathematical studies. What was done in this step affects all three terms on the inside of the brackets. Minus signs are real bad things to misuse. Study carefully how to change the signs when multiplying by a minus. 

Rule a minus sign outside the brackets, when multiplied by anything inside the brackets, change the sign to the opposite of what it was.

-20 + 4x + 5x^2 = 20 - 7x^2

Comment
Before doing the last step, look at the answers. Two of them are 40. That is the answer for 20 and -20 when transferred. It's 40 which is a plus. So you should be transferring from left to right.

Step Two 
Transfer from left to right.
-20 + 4x + 5x^2 = 20 - 7x^2      Add 20 to both sides.
4x + 5x^2 = 20 + 20 - 7x^2      Subtract 4x from both sides.
5x^2 = 40 - 7x^2 - 4x                Subtract 5x^2 from both sides
0 = 40 - 7x^2 - 5x^2 - 4x
0 = 40 - 12x^2 - 4x                   Now you have to put them in the right order.

0 = 40 - 4x - 12x^2 <<<<< Answer   


what is the quotient of 15p^-4q^-6/-20^12q^-3 in simplified form

Answers

The first step for solving this problem is to reduce the fraction with [tex] q^{-6} [/tex].
[tex] \frac{15p^{-4} }{-20^{12} q^{3} } [/tex]
Determine the sign of the fraction.
[tex] -\frac{15p^{-4} }{20^{12} q^{3} } [/tex]
Now if a negative exponent is in the numerator,, then you must move the expression to the denominator and then make the exponent positive. This will change the expression to the following:
[tex]- \frac{15}{ 20^{12} q^{3} p^{4} } [/tex]
Lastly,, use the commutative property to reorder the terms on the bottom of the fraction.
[tex]- \frac{15}{ 20^{12} p^{4} q^{3} } [/tex]
Since we cannot simplify this expression any further,, the correct answer to this question is [tex]- \frac{15}{ 20^{12} p^{4} q^{3} } [/tex].
Let me know if you have any further questions.
:)

The simplified form of the expression: [tex]\( -\frac{15}{2^{24} \times 5^{12} \times p^4 \times q^3} \)[/tex]

To simplify the expression [tex]\( \frac{15p^{-4}q^{-6}}{-20^{12}q^{-3}} \)[/tex], we can apply the rules of exponents and simplify each part of the expression separately.

First, let's rewrite [tex]\( -20^{12} \) as \( -(20^{12}) \)[/tex] to make it clear that the exponent applies to the entire term:

[tex]\[ \frac{15p^{-4}q^{-6}}{-(20^{12}q^{-3})} \][/tex]

Now, let's simplify each part:

1. \( p^{-4} \) can be rewritten as [tex]\( \frac{1}{p^4} \).[/tex]

2. \( q^{-6} \) can be rewritten as [tex]\( \frac{1}{q^6} \).[/tex]

3. [tex]\( 20^{12} \)[/tex] can be calculated.

[tex]\[ \frac{15}{-(20^{12})} \times \frac{1}{p^4} \times \frac{1}{q^6} \times \frac{1}{q^{-3}} \][/tex]

Now, let's calculate [tex]\( 20^{12} \):[/tex]

[tex]\[ 20^{12} = (2^2 \times 5)^{12} = 2^{24} \times 5^{12} \][/tex]

[tex]\[ = (2^4)^6 \times 5^{12} = 2^{24} \times 5^{12} \][/tex]

Now, we can rewrite the expression:

[tex]\[ \frac{15}{-(2^{24} \times 5^{12})} \times \frac{1}{p^4} \times \frac{1}{q^6} \times \frac{1}{q^{-3}} \][/tex]

[tex]\[ = -\frac{15}{2^{24} \times 5^{12} \times p^4 \times q^6 \times q^{-3}} \][/tex]

[tex]\[ = -\frac{15}{2^{24} \times 5^{12} \times p^4 \times q^3} \][/tex]

This is the simplified form of the expression.

The width of a rectangle is 6 kilometers less than twice its length. if its area is 108 square​ kilometers, find the dimensions of the rectangle.

Answers

Let x = the length 
2x - 6 = the width as given in the description.

Area of a rectangle is length * width. Now we plug in.

108 = x(2x - 6)
108 = 2x² - 6x

We are going to get all terms on the same side and factor. 

2x² - 6x - 108 = 0

Factor out and divide each term by a GCF of 2 to get: 

x² - 3x - 54 = 0

x² + 6x - 9x - 54 = 0
x(x + 6) - 9(x + 6) = 0

Your factors are (x + 6)(x - 9) = 0. Now we set each binomial equal to zero. This gives us x = - 6 and x = 9. Distance cannot be measure in negative numbers so we know to use x = 9 to find our measurements.

The length (x) is 9 kilometers. The width (2x - 6) is 12 kilometers when you plug in 9 where the x is. 

The dimensions of the rectangle are [tex]\( \boxed{9 \text{ km} \times 12 \text{ km}} \)[/tex].

Let's denote the length of the rectangle as [tex]\( l \)[/tex] kilometers, and its width as [tex]\( w \)[/tex] kilometers.

From the problem statement, we have two pieces of information:

1. The width is 6 kilometers less than twice the length:

  [tex]\[ w = 2l - 6 \][/tex]

2. The area of the rectangle is 108 square kilometers:

  [tex]\[ lw = 108 \][/tex]

Now we can substitute the expression for \( w \) from the first equation into the second equation:

[tex]\[l(2l - 6) = 108\][/tex]

Expand and simplify the equation:

[tex]\[2l^2 - 6l = 108\][/tex]

Subtract 108 from both sides to set the equation to zero:

[tex]\[2l^2 - 6l - 108 = 0\][/tex]

Divide every term by 2 to simplify:

[tex]\[l^2 - 3l - 54 = 0\][/tex]

Now, we'll solve this quadratic equation using the quadratic formula, [tex]\( l = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \)[/tex], where [tex]\( a = 1 \)[/tex], [tex]\( b = -3 \)[/tex], and [tex]\( c = -54 \)[/tex]:

[tex]\[l = \frac{-(-3) \pm \sqrt{(-3)^2 - 4 \cdot 1 \cdot (-54)}}{2 \cdot 1}\][/tex]

[tex]\[l = \frac{3 \pm \sqrt{9 + 216}}{2}\][/tex]

[tex]\[l = \frac{3 \pm \sqrt{225}}{2}\][/tex]

[tex]\[l = \frac{3 \pm 15}{2}\][/tex]

This gives us two possible solutions for [tex]\( l \)[/tex]:

[tex]\[l = \frac{18}{2} = 9 \quad \text{or} \quad l = \frac{-12}{2} = -6\][/tex]

Since length cannot be negative, we take [tex]\( l = 9 \)[/tex] kilometers.

Now, substitute [tex]\( l = 9 \)[/tex] back into the expression for [tex]\( w \)[/tex]:

[tex]\[w = 2l - 6 = 2 \cdot 9 - 6 = 18 - 6 = 12\][/tex]

Therefore, the dimensions of the rectangle are:

- Length [tex]\( l = 9 \)[/tex] kilometers

- Width [tex]\( w = 12 \)[/tex] kilometers

To verify, calculate the area:

[tex]\[l \times w = 9 \times 12 = 108 \text{ square kilometers}\][/tex]

Since this matches the given area, the dimensions [tex]\( l = 9 \)[/tex] kilometers and [tex]\( w = 12 \)[/tex] kilometers are correct.

Thus, the dimensions of the rectangle are [tex]\( \boxed{9 \text{ kilometers} \times 12 \text{ kilometers}} \)[/tex].

You have a government bond when a government bond issues a direct obligation.
Common and preferred stock both represent the ownership of a corporation, but preferred stockholders are paid before common stockholders, both in good and bad times.

The fact that we have two containers of water is all that matters. In this example,the water is like the polynomial. Combining the two containers of water into one will result in a greater amount of water. Combining water with water leads to more water.

Answer:

a) monomial
b) constant
c) binomial
d) trinomial
e) binomial
f) constant
g) monomial

Step-by-step explanation:

Let's start by defining the terms in the question:
A monomial is an expression with a single term, regardless of how many variables are in the term.
A binomial is an expression with two different terms, which cannot be combined into a single term due to their variables not matching.
A trinomial is an expression with three different terms, which cannot be combined into a binomial or monomial because their variables do not match.
A constant is an integer that lacks a variable attached to it. An integer with a variable attached to it would be a monomial, and the integer itself would be called a coefficient.

Now, we can get into the parts of the question:
a) 8a²b is two variables however it is still a single term so this is a monomial.

b) -39 is an integer with no variables attached. Therefore, it is a constant.

c) x + y is two variables and two different terms that cannot be combined into one single term. It is a binomial.

d) -12xy + 5y - x² showcases three different variables and three different terms that cannot be consolidated. Thus, it is a trinomial.

e) 2x² + 2y² demonstrates two different variables and two different terms that are not alike. As such, we have a binomial.

f) 3/4 is an integer with no variables in sight. We have here a constant.

g) -32m²n² has two variables but is only a single term on its own. This is a monomial.

Two angels re supplementary. The larger angle is 48 degrees more than the 10 times the smaller angle. Find the measure of each angle.

Answers

Supplementary angles are two angles that add up to 180°.

STEP 1:
find the value of x

x= smaller angle
10x + 48= larger angle

Add the two angles above to equal 180.

x + (10x + 48)= 180
combine like terms

11x + 48= 180
subtract 48 from both sides

11x= 132
divide both sides by 11

x= 12° smaller angle


STEP 2:
find the value of the second angle

=10x + 48
=10(12) + 48
=120 + 48
=168° larger angle


CHECK:
12° + 168°= 180°
180°= 180°


ANSWER: The smaller angle is 12° and the larger angle is 168°.

1.75 + 2 + 2.25 + 2.5 + 2.75 + 3 + 3.25 + 3.5 + 3.75 + 4 + 4.25 + 4.5 + 4.75 + 5 + 5.25 + 5.5 + 5.75 + 6 = 69.75

The answer is B) 69.75 mi

Hope this helps!
On the 18th day, Akim runs 1.75 + 17×0.25 = 6 miles. Then his average mileage each day over the period is (1.75 +6)/2 = 3.875 miles.

Akim's total mileage is 18×3.875 = 69.75 miles. . . . . . . matches the 2nd choice

You can print a copy of the graph, stick a pin in the origin, and rotate it 180° to see where the figure ends up.

The origin is the midpoint between each vertex and its image.
Negate every coordinate value, for example, J(-5, -3) gets rotated to J'(5, 3).


Marilyn uses a credit card with a 19.9% APR compounded monthly to pay for car repairs totaling $991.38. She can pay $410 per month on the card. What will the total cost of this purchase be?

$1,021.01

$1,188.66

$991.38

$1,192.39

Answers

Marilyn's finance charge at the end of the first month will be
  $991.38 × 0.199/12 = $16.44
The balance subject to the next month's finance charge will be
  $991.38 +16.44 -410.00 = $597.82

The finance charge at the end of the second month will be
  $597.82 × 0.199/12 = $9.91
The balance remaining after the second payment will be
  $597.82 +9.91 -410.00 = $197.73

The finance charge applied at the end of the third month is
  $197.73 × .199/12 = $3.28
so Marilyn can make one final payment of
  $197.73 +3.28 = $201.01
to pay off the balance.

In all, Marilyn has paid 2×$410.00 +201.01 = 
  $1021.01 . . . . . . . . corresponds to the first choice

_____
In real life, Marilyn's credit card may not accrue any finance charge until after the first statement on which the charge appears. Thus the total cost of the purchase may be only $1004.02. The attached spreadsheet shows the beginning balance and the finance charges for each month for the two different scenarios.

What is a correct first step in solving the inequality –4(3 – 5x)≥ –6x + 9?

Answers

use the distributive property to simplify the left side 

-12 + 20x >= -6x + 9
In order to solve the inequality, You need to work the parenthesis, -4(3-5x)>-6x=9.
-12+20x>-6x+9
-12+26x>9
26x>21
Now divide both sides by 26, and the answer is:
Answer: x is greater than or equal to 21/26 (21 over 26)

A 12.0-cm segment makes a 108.0-degree angle with a 16.0-cm segment. To the nearest tenth of a cm, find the third side of the triangle determined by this SAS information.

Answers

Begin by using the cosine rule to find the unknown side.

Where a- unknown side, b is 12, c is 16 and angle in between is 108° 

The cosine rule...

        a² = b² + c² - 2bc cosA

            = 12² + 16² - (2×12×16 cos108°)

            = 518.655076

Taking the positive square root...

         a = 22.774 

         a = 22.8 cm nearest tenth

Final answer:

The question involves finding the length of the third side of a triangle using the Law of Cosines. The known parameters are two sides and the included angle. The formula c² = (12 cm)² + (16 cm)² - 2*(12 cm)*(16 cm)*cos(108 degrees) can be used to calculate the length of third side.

Explanation:

In this problem, you're dealing with a triangle and need to find the length of the third side. This is a classic case of using the Law of Cosines - a geometric rule that helps you find the length of a side of a triangle when you know the lengths of the other two sides and the angle in between (or in this case, SAS information).

The Law of Cosines formula is: c² = a² + b² - 2ab*cos(C), in which 'a' and 'b' represent the sides of the triangle adjacent to angle 'C', and 'c' is the other side. In your case, 'a' is 12.0 cm, 'b' is 16.0 cm and angle 'C' is 108.0 degrees. The third side 'c' can be calculated accordingly.

So, in this scenario, c² = (12 cm)² + (16 cm)² - 2*(12 cm)*(16 cm)*cos(108 degrees). With some basic arithmetic and the use of a calculator to compute the cosine, you can determine the length of the third side, 'c', to the nearest tenth of a cm.
