The partial fraction of [tex]\frac{x+4}{x^{2} +x}[/tex] is as follows

[tex]\frac{x+4}{x^{2} +x} =-\frac{3}{x+1}+\frac{4}{x}[/tex]

Partial fraction is the result of writing a rational expression as the sum of two or more fractions.

Therefore,

[tex]\frac{x+4}{x^{2} +x} =\frac{A}{x+1}+\frac{B}{x}[/tex]

Let's find the zeros of (x + 1) and (x)

when x = -1

Ax + B(x + 1) = x + 4

x + 4 = A(-1) + B(-1 + 1)

-A = -1 + 4

A = -3

when x = 0

A(0) + B(0 + 1) = 0 + 4

B = 4

Therefore,

[tex]\frac{x+4}{x^{2} +x} =-\frac{3}{x+1}+\frac{4}{x}[/tex]

Answer:

-12

Step-by-step explanation:

Apply the radical rule :  [tex]\sqrt[n]{-a} =-\sqrt[n]{a}[/tex]

Therefore, [tex]\sqrt[3]{-1728} =-\sqrt[3]{1728}[/tex]

Factorise 1728:   [tex]1728=12^3[/tex]

Therefore, [tex]\sqrt[3]{-1728} =-\sqrt[3]{12^3}[/tex]

Apply the radical rule:  [tex]\sqrt[n]{a^n} =a, \ \ \ \ a\geq 0[/tex]

Therefore, [tex]-\sqrt[3]{12^3}=-12[/tex]

Answer:

$2,975

Step-by-step explanation:

Discount = Original Price x Discount %/100

Discount = 3500 × 15/100

Discount = 3500 x 0.15

You save = $525.00

Final Price = Original Price - Discount

Final Price = 3500 - 525

Final Price = $2,975.00

Answer:

add x to both sides. once you do this, you will get x+y=15

Answer:

14/21

Step-by-step explanation:

14/21 is the correct answer because

We need to find the LCM or least common multiple between the denominator of 2/3 (which is 3) and 21.

The least common multiple between 3 and 21 is 21. This is because 21 is a multiple of 3.

21/3= 7

Both the numerator and denominator of 2/3 needs to be multiplied by 7 which gives a value of 14/21.

2×7= 14

3×7= 21

Answer:

6

Step-by-step explanation:

#1: 4x - 8 = 16 (You want to remove -8)

#2: 4x = 24 (In order to remove -8 you need to cancel it out, add 8 to -8, also add 8 to 16)

#3: 4x = 24 (Now you need to get the x by itself, divide 4x by 4 to only get x and also divide 24 by 4)

#4: x = 6

Answer:

see explanation

Step-by-step explanation:

to find f(g(x)) , substitute x = g(x) into f(x)

f(g(x))

= f(3x + 1)

= (3x + 1)² + 9(3x + 1) ← expand parenthesis

= 9x² + 6x + 1 + 27x + 9 ← collect like terms

= 9x² + 33x + 10

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

to find g(f(x)), substitute x = f(x) into g(x)

g(f(x))

= g(x² + 9x)

= 3(x² + 9x) + 1 ← distribute parenthesis

= 3x² + 27x + 1

Answer:

blue line: 20

black line: -20

Step-by-step explanation:

use rise (y) over run (x)! as the blue line goes from points (8,80) to (9,100) the difference in the x or run is 1 while the difference in the y or rise is 20 which makes it 20/1 = 20. for the black line, because it's going down it indicates it will be a negative slope, use the same trick as last time, our first point is (5,20) and our next point is (6,0) the difference in x is 1 and the difference in y is -20, so -20/1 = -20! hope this helped :-)

1) For our first job, PROBLEM A, it has a mean of 515 points and a standard deviation of 114 points. We're given the goal of calculating what % belongs between 401 and 629. As we can see, if we remove 515, then subtract 114 from 515, we obtain our first value of 401, then if we add our standard deviation tournament, we get our second number of 629. So, using the empirical rule, we know that in this scenario, 68 of our data points will fall inside this range.

2) Part B requires us to identify the scores that are less than 401 and larger than 629. So, in part A, we have the inclusive section of this, and now we have the exclusive section. Simply remove 60 percent from 100 percent, and we get 32 percent outside of this range.

Answer: 1/4

Step-by-step explanation: we need a common denominator of 3 and 12, by multiplying 3 x 4 = 12 then 1 x 4, we then have the fraction 4/12. subtract 1/12 then you have 3/12 we then simplify by dividing the numerator and denominator by the same number = 1/4

Answer:

1/3 - 1/12 = 4/12 - 1/12= 3/12

Step-by-step explanation:

- Get 1/3 the same denominator as the 1/12

- to do that you multiply the 3 by 4 you get 1/12

- I was taught whatever you do at the bottom you have to do on top so multiply the 1 by 4 and now you have 4/12

- plug in 4/12 to the equation

- 4/12 -  1/12 = 3/12 or the simplified version is 1/4

Answer:

Equation: y - 3x/4 + 4

Step-by-step explanation:

using the formula:

So using the formula:

Answer:

y = 3/4(x) + 4

Step-by-step explanation:

The slope-intercept equation of a line can be written as y = mx + b, where y = y-coordinate, m = slope, x = x-coordinate, and b = y-intercept.

We are given the slope (m) as 3/4 and the y-intercept (b) as 4. Thus, when we plug in values of m and b, we get the equation of y = 3/4(x) + 4.

Answer:

This is a nonlinear function.

Not in s straight line.

Step-by-step explanation:

Linear functions are straight lines, however a nonlinear function is a curved line. At the end of the line, the line curves a little bit.

The graph of a function is non linear function because it is not a straight line.

The given graph is a non linear function.

The graph represents a non-linear function, which means that it does not follow a straight line.

The relationship between the x-values and the corresponding y-values is not linear.

The graph is rising from right to left, indicating that as the x-values decreases, the corresponding y-values increase.

Answer:4.7 qt of liquid is needed. If doubled, 8/7 qts of liquid is needed. if halved, 2/7 qts of liquid is needed.

Step-by-step explanation:

Add the two amounts of liquid to get the total amount of liquid:

1/7 qt + 3/7 qt = 4/7 qt (cannot be simplified further)

To double the recipe, multiply the total liquid amount by 2.

4/7 * 2/1 = 8/7

To half the recipe, multiply the total liquid amount by 1/2.

4/7 * 1/2 = 4/14 --> 2/7
