Divide 2(x^4 +9) by x(x^2 +1)
1. We need to perform a division by multiplying the dividend with the reciprocal of the divisor. We can apply this rule:
[tex](\frac{A}{B})/(\frac{C}{D} )=(\frac{A}{B}) (\frac{C}{D})[/tex]In the problem... [tex]2(x^4 +9)/x(x^2 +1)[/tex]
A = [tex]2(x^4+9)[/tex]B = 1C =[tex]x(x^2+1)[/tex]D = 1[tex]2(x^4 +9)/x(x^2 +1)[/tex] changes to [tex](2(x^4+9))(\frac{1}{x(x^2+1)}[/tex]
2. We need to get rid of all the parenthesis in this term. [tex](2(x^4+9))(\frac{1}{x(x^2+1)}[/tex]
All negative factors will change the sign.In the problem [tex](2(x^4+9))(\frac{1}{x(x^2+1)}[/tex] there isn't any negative factors. So the sign will not change.[tex](2(x^4+9))(\frac{1}{x(x^2+1)}[/tex] is now [tex]2(x^4+9)(\frac{1}{x(x^2+1)}[/tex]
3. Lastly, we need to perform a multiplication.
We can use this rule: [tex]\frac{A}{B} C=\frac{AC}{B}[/tex]In the problem [tex]2(x^4+9)(\frac{1}{x(x^2+1)}[/tex] the new factors on the numerator are: [tex]2, (x^4+9), 1[/tex]Notice that all non-fraction factors are placed in the numerator.The new factors in the denominator are: [tex]x, (x^2+1),[/tex]Therefore, the answer is: [tex]\frac{2(x^4+9)}{x(x^2+1)}[/tex]

Answer:
-3/5
Step-by-step explanation:
Slope is calculated with the formula m=(y_2 - y_1)/(x_2-x_2). The starting point I put as (0,0) and the finish is (5,-3). I used one city block is equal to one. Thus 3 blocks south(y-axis), is -3 and 5 east(x-axis) is 5. So plug into the equation with y_2 as -3 and x_2 as 5 then y_1 and x_1 both as zero. Thus slope=m= -3/5.

The area of a regular nonagon is 150 square cm. What is the area of a regular nonagon with sides three times the sides of the smaller nonagon?
Answer:
1,350 square cm
Step-by-step explanation:
As we all know, we have to square a dimension of length to get the dimension of an area
So in this case, since the dimension of the length is increasing by a factor of 3, the dimension of the area will be increasing by a factor which is square the factor by which the dimension of the side is increasing
Thus, we have the area dimension increase by a factor of 3^2 = 9 times the area of the smaller
nonagon
So the area of the bigger nonagon will be :
150 * 9 = 1,350 square cm
1. Carter sold 9 of his video games online. The next day, he sold
27 video games. He collected a total of $900. If he charged the
same amount for each video game, how much did he sell each
game for?
Answer:
$25
Step-by-step explanation:
total of 36 games sold, gained a total of $900. To find the cost of each game, divide 900 by 36, which is 25. So each game costs $25.
Determine whether the equation below has a one solutions, no solutions, or an
infinite number of solutions. Afterwards, determine two values of x that support your
conclusion
2 + 6 = 9
The equation has infinite solutions
A value of x that makes the equation true is
3
which when substituted into the
equation and simplified makes the equation turn into
х
3
Another value of x that makes the equation true is -15 , which when substituted
into the equation and simplified makes the equation turn into 3

What is probability?Probability is the measure of the likelihood that an event will occur in a Random Experiment. Probability is quantified as a number between 0 and 1, where, loosely speaking, 0 indicates impossibility and 1 indicates certainty. The higher the probability of an event, the more likely it is that the event will occur.
Given:
Joe is shown 3 cards marked 2, 5 and 9.
we have write all the possible 3digit numbers
First taking 2 at hundred place value
259
295
Now, taking 5 at hundred place value

Determine the inverse of the following.

[tex]f^{-1}[/tex](x)=[tex]10^{-x+2}[/tex]+1
Step-by-step explanation:
A line has an x-intercept of 2 and a y-intercept of 5. What is the equation of the line?
Answer:
y = -2.5x + 5
Step-by-step explanation:
Here, given the x and y intercept, we want to write the equation of the line
The general equation form is;
y = mx + b
where m is the slope and b is the y-intercept
Using the given points, we have that;
(2,0) and (0,5)
b is 5
so we have;
y = mx + 5
to get m, set (2,0); x = 2 and y = 0
0 = 2m + 5
2m = -5
m = -5/2 = -2.5
So the equation is;
y = -2.5x + 5

54:19 To eliminate the terms and solve for y in the fewest steps, by which constants should the equations be multiplied by before adding the equations together? First equation: 9x + 3y = -18 Second equation: 8x + 7y = 10 The first equation should be multiplied by 3 and the second equation by 7. The first equation should be multiplied by -3 and the second equation by -7. The first equation should be multiplied by - 7 and the second equation by 3 . The first equation should be multiplied by -7 and the second equation by -3.
Answer:
The first equation should be multiplied by - 7 and the second equation by 3
Step-by-step explanation:
Given
[tex]9x + 3y = -18[/tex] -- (1)
[tex]8x + 7y = 10[/tex] -- (2)
Required
How to eliminate y
In (1), the coefficient of y = 3
In (2), the coefficient of y = 7
Multiply the first equation by -7
[tex]-7(9x + 3y = -18)[/tex]
[tex]-63x -21y = 126[/tex] --- (3)
Multiply the second by 3
[tex]3(8x + 7y = 10)[/tex]
[tex]24x + 21y = 30[/tex] -- (4)
Add the results together:
[tex]-63x -21y = 126[/tex]
[tex]24x + 21y = 30[/tex]
[tex]-------------------------[/tex]
[tex]-63x + 24x -21y +21y = 126+30[/tex]
[tex]-63x + 24x = 126+30[/tex]

A taxi charges $1.75 plus a fee of $0.75 for each mile traveled. The total cost of a ride, without a tip, is $4.75. How many miles is the trip?
Answer:
The trip contains 4 miles.
Step-by-step explanation:
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the rate of change or slopeb is the y-interceptGiven that A taxi charges $1.75, meaning the initial condition of the trip is to charge $1.75.
Thus, y-intercept b = 1.75
Also, the taxi charges a fee of $0.75 for each mile traveled.
Thus, rate of change or slope m = 0.75
Let 'y' be the total cost
Let 'x' be the number of miles
Given that the total cost of a ride, without a tip, is $4.75.
so substitute y = 4.75, rate of change or slope m = 0.75, and the y-intercept b = 1.75 in the slope-intercept form of the line equation
y = mx + b
4.75 = 0.75(x) + 1.75
switch sides
0.75(x) + 1.75 = 4.75
subtract 1.75 from both sides
0.75x + 1.75 - 1.75 = 4.75 - 1.75
0.75x = 3
divide both sides by 0.75
0.75x/0.75 = 3/0.75
x = 4 miles
Therefore, the trip contains 4 miles.
13x = 130 Solve for x
Answer:
x = 10
Step-by-step explanation:
You need to isolate x, so divide by 13. 130/13 = 10.
Simplified, x = 10.
The solution to the given equation is 10.
The given equation is 13x = 130.
The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.
Here, transpose 13 to the other side of the equation, we get
13x = 130
x=130/13
x=10
Therefore, the solution to the given equation is 10.

Allan needs 3 quarts of water to fill a pot for soup.How many times of he need to fill an 8-ounce measuring cup to fill the pot
Answer:
12 times
Step-by-step explanation:
1 quart = 32 ounces
3 quart = x
x = 3 × 32 ounces
x = 96 ounces
The number of times of he need to fill an 8-ounce measuring cup to fill the pot is calculated as:
= 96 ounces/8 ounces measuring cup
= 12 times
Therefore, Alan needs to fill an 8 ounce measuring cup 12 times in order to fill the pot of soup.

−4x−24x+24=10(12−2x) explain how you sloved it...i rllly need this!!!!
Answer:
x=-12
Step-by-step explanation:
first collect all the like terms -28x + 24 = 120-20x
then move variables and constants to the correct side -28x + 20x = 120-24
collect like terms again -8x = 96
divide both side by -8 so -8x/-x n 96/-8 you get x=-12 bc -8 time -12 = 96
Answer:
x = -12
Step-by-step explanation:
First, combine like terms
[tex]-4x-24x+24 = 10(12-2x)\\-28x+24 = 10(12-2x)[/tex]
Then, use the distributive property on the right side
[tex]-28x + 24 = 120 - 20x[/tex]
Now, add 28x to both sides to get the Xs all together
[tex]24 = 120 + 8x[/tex]
Next, subtract 120 from both sides:
[tex]-96 = 8x[/tex]
divide both sides by 8:
[tex]-12 = x[/tex]
This means the answer is x = -12
