What is the simplified form of x+6/2x+5 + x+5/x+3

Answer:

2

4

8

increases

Step-by-step explanation:

The average rate of change between x-values can be calculated by using the formula [tex](f(x2) - f(x1))/(x2 - x1).[/tex]. For x = 1 and x = 2, the rate is 2; for x = 2 and x = 3, the rate is -4; and for x = 3 and x = 4, the rate is 8.

The question asks about the average rate of change between certain points on an x-axis. In mathematics, the average rate of change is calculated by dividing the change in the output by the change in the input. In other words, it reflects how much the function's value (y-coordinate) changes when the input (x-coordinate) moves 1 unit.

To find the average rate of change, use the formula [tex](f(x2) - f(x1))/(x2 - x1).[/tex] In this case:

Answer:

Tom can cut 12 (15 inch pieces) from the two boards.

Step-by-step explanation:

We're first given foot measurements and we're asked to find the answer in inches. That means we must convert 8 feet to inches, which is a 1:12 inches conversion. 8 times 12 will give you 96, so now you will multiply that value by 2 because Tom has 2 8-foot long boards. That will give you 192 inches. Since the question is asking for 'how many 15 inch pieces he can cut from the two boards?', you will need to divide 192 inches by 15 to find the answer. This will give you 12.8 boards. Because you can't have parts of an object, the answer will be 12 whole boards.

Lainey paid 30 cents (equivalent to $0.30) for each marker in the set.

To find the cost of 1 marker, you can divide the total cost by the number of markers.

Cost of 1 marker = Total cost / Number of markers

In this case, the total cost is $6, and the number of markers is 20.

Cost of 1 marker = $6/20

Simplifying the expression:

Cost of 1 marker=$0.30

Therefore, the cost of 1 marker is $0.30.

Think of the cost as being divided equally among all 20 markers. By dividing the total cost ($6) by the number of markers (20), we find the share of the cost for each marker ($0.30).

Final answer:

There are 4 cups in 1 quart of milk.

Explanation:

In 1 half quart of milk, there are 2 cups. To find out how many cups are in 1 quart of milk, we can set up a proportion:

2 cups / 1 half quart = x cups / 1 quart

Cross multiplying, we get:

2 * 1 quart = 1 half quart * x cups

2 quarts = 0.5 quarts * x cups

Dividing both sides by 0.5 quart, we find that:

x = 2 * 2 = 4

Therefore, there are 4 cups in 1 quart of milk.

Answer:

"Domain of set B: {2, 4,-4, 0}"

Step-by-step explanation:

When it the set A,B,C (and others) are given in this form it means that the coordinate pairs are the domain and range of each set, respectively.

The first coordinate is part of the domain (x) and the second coordinate is part of the range (y).

For example, the domain of A is all the numbers that are the first in each coordinate pair, so domain of A would be 1, -1, and 6.

Likewise, the domain of B would be 2, 4, -4, and 0.

Hence,

Domain of set B: {2, 4,-4, 0}  --  is the correct answer.

Step-by-step explanation:

Given (x, y) is a point on f(x), then the corresponding point on the inverse g(x) is (y, x)

Hence

(8, 3) → (3, 8)

(4, 1) → (1, 4)

(0, - 1) → (- 1, 0)

(- 4, - 3) → (- 3, - 4)

That is the last set of points represents g(x)

Answer:

40(1.25-t)

Step-by-step explanation:

There are 3 components to consider; time, speed and distance

Time and Speed are given.

The distance has to be calculated.

Distance for trip to home

Speed = Distance/Time

40 = Total Distance/1.25-t

Total Distance = 40(1.25-t)

Therefore, 40(1.25-t) is the correct answer.

!!

Answer:

Option C. 40(1.25 - t)

Step-by-step explanation:

Eduardo's average speed on his commute to work = 55 miles per hour

On the way home his average speed was = 40 miles per hour

Round trip took him 1.25 hours.

Let t be the total time taken by Eduardo for the trip to work.

Then time taken on the way home = Total time for round trip - Time taken from work to home

                                                          = (1.25 - t) hours

Average speed = [tex]\frac{\text{Distance}}{\text{Time}}[/tex]

40 = [tex]\frac{\text{Distance}}{(1.25-t)}[/tex]

Now the distance for his trip home can be represented by

Distance = 40(1.25 - t)

Option C. 40(1.25 - t) will be he answer.

Answer:

x>-2

Step-by-step explanation:

Solving x+2>0 gives you x>-2

Answer:

(g°f)x =16 when x = 5

Step-by-step explanation:

It might be easier to understand if you wrote this the other acceptable way.

g(x) = x^4

f(x) = 2x - 8

g(f(x))  means that in g(x) wherever you see and x you put f(x)

g(f(x)) = (f(x) ) ^ 4 Now put in the general value for f(x)

g(2x - 8) = (2x - 8)^4

You really don't want to expand this (although it would give you the right answer eventually).

g(2*5 - 8) = (2 * 5 - 8)^4

g(2*5 - 8) = (10 - 8)^4

g(2*5 - 8) = 2^4

Answer:  The required simplified answer in standard form is [tex]8y^6-88y^5-6y^3+61y^2+55y.[/tex]

Step-by-step explanation:  We are given to multiply the following polynomials and write the answer is standard form :

[tex]M=(-6y+8y^4-5)(y^2-11y)~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]

To multiply the given polynomials, we need to multiply each term of one polynomial to each term of the other polynomial.

From (i), we have

[tex]M\\\\=(-6y+8y^4-5)(y^2-11y)\\\\=y^2(-6y+8y^4-5)-11y(-6y+8y^4-5)\\\\=-6y^3+8y^6-5y^2+66y^2-88y^5+55y\\\\=8y^6-88y^5-6y^3+61y^2+55y.[/tex]

Thus, the required simplified answer in standard form is [tex]8y^6-88y^5-6y^3+61y^2+55y.[/tex]

Answer:

7740° / 45

Step-by-step explanation:

The sum of the interior angles is given by this formula: (n - 2) * 180°. So a regular 45-gon would have interior angles that add up to: (45 - 2) * 180°. = 43 * 180°. = 7740°. Now divide that by the 45 angles to find the measure of one interior angle

hope that helped :(

The measure of each exterior angle of a regular 45-gon is calculated using the formula: Exterior Angle = 360° / Number of Sides. Hence, each exterior angle of a 45-gon measures 8°.

In mathematics, the measure of each exterior angle of a regular polygon can be found using the formula: Exterior Angle = 360° / Number of Sides. So, to find the measure of an exterior angle in a 45-sided shape, or 45-gon, you would perform the calculation: 360° / 45 = 8°.

This indicates that each exterior angle of a regular 45-gon measures 8 degrees. This is a key concept to remember when working with regular polygons, as it can be used to determine other characteristics of the shape such as the sum of the exterior angles, which in any polygon is always 360°.

Answer:

See explanation

Step-by-step explanation:

Let x be the number of spade shovels, y -the number of flat shovels and z - the number of square showels sold that day.

The store keeps an inventory of 80 shovels, then

x+y+z=80

The store always buy twice as many spade shovels as square, so

x=2z

The total cost of all shovels is

16x+9.60y+12.80z=1,072

a) The system of three equations is

[tex]\left\{\begin{array}{l}x+y+z=80\\ \\x=2z\\ \\16x+9.60y+12.80z=1,072\end{array}\right.[/tex]

b) In matrix form this is

[tex]\left(\begin{array}{ccc}1&1&1\\ 1&0&-2\\ 16&9.60&12.80\end{array}\right)\cdot \left(\begin{array}{c}x\\y\\z\end{array}\right)=\left(\begin{array}{c}80\\0\\1,072\end{array}\right)[/tex]

c) The determinant is

[tex]\left\|\begin{array}{ccc}1&1&1\\ 1&0&-2\\ 16&9.60&12.80\end{array}\right\|=0-32+9.60-0+19.20-12.80=-16[/tex]

d) Find three determinants:

[tex]\left\|\begin{array}{ccc}80&1&1\\ 0&0&-2\\ 1,072&9.60&12.80\end{array}\right\|=0-2,144+0-0+1,536-0=-608[/tex]

[tex]\left\|\begin{array}{ccc}1&80&1\\ 1&0&-2\\ 16&1,072&12.80\end{array}\right\|=0-2,560+1,072-0+2,144-1,024=-368[/tex]

[tex]\left\|\begin{array}{ccc}1&1&80\\ 1&0&0\\ 16&9.60&1,072\end{array}\right\|=0+0+768-0-0-1,072=-304[/tex]

So,

[tex]x=\dfrac{-608}{-16}=38\\ \\y=\dfrac{-368}{-16}=23\\ \\z=\dfrac{-304}{-16}=19[/tex]

e) If the store doubled all prices and inventory, then the new matrix is

[tex]\left(\begin{array}{ccc}1&1&1\\ 1&0&-2\\ 32&19.20&25.60\end{array}\right)\cdot \left(\begin{array}{c}x\\y\\z\end{array}\right)=\left(\begin{array}{c}160\\0\\2,144\end{array}\right)[/tex]
