What is the partial fraction decomposition of<br> 7x squared- 6x +9/<br> 3x(4x squared +9)
Anit [1.1K]

9514 1404 393

Answer:

  1/(3x) =(x -2)/(4x^2 +9)

Step-by-step explanation:

The denominator cannot be factored further, so the final form will be ...

  A/(3x) + (Bx +C)/(4x^2 +9)

The value of this is ...

  (A(4x^2 +9) +(3x)(Bx +C))/(3x(4x^2 +9))

  = ((3B+4A)x^2 +3Cx +9A)/(3x(4x^2 +9))

Equating coefficients gives ...

  3B+4A = 7

  3C = -6   ⇒   C = -2

  9A = 9   ⇒   A = 1

Using the found value of A, we find ...

  3B +4 = 7   ⇒   B = 1

Then the decomposition is ...

  \dfrac{7x^2-6x+9}{3x(4x^2+9)}=\boxed{\dfrac{1}{3x}+\dfrac{x-2}{4x^2+9}}

Two consecutive integers have a sum of 67. What are the two integers?
Eduardwww [97]
<h3>♫ :::::::::::::::::::::::::::::: // Hello There ! //  :::::::::::::::::::::::::::::: ♫</h3>

➷  We can call the first integer 'x'

Thus, the second integer would be 'x + 1'

From this, we can form an equation:

x + x + 1 = 67

Simplify this:

2x + 1 = 67

- 1 from both sides:

2x = 66

Divide both sides by 2:

x = 33

Therefore, x + 1 = 34

The 2 integers are 33 and 34.

What is the interest rate if...<br> Principal = $1,250<br> Time = 4 years<br> Interest = $285.
alexandr402 [8]

Answer:

<h3>The answer is 5.7 %</h3>

Step-by-step explanation:

To find the rate given the principal , time and interest , we use the formula

r =  \frac{100I}{pt}  \\

where

p is the principal

t is the time

I is the interest

From the question

Principal = $1,250

Time = 4 years

Interest = $285

We have

r =  \frac{285 \times 100}{4 \times 1250}  =  \frac{28500}{5000}  =  \frac{285}{50}  \\  = 5.7

We have the final answer as

<h3>5.7 %</h3>

Hope this helps you

Solve the inequality for x. -4x -6 &lt;50
Nostrana [21]

Answer:

x >-14

Step-by-step explanation:

To solve the inequality, we need to isolate the variable, x

-4x -6 <50

Add 6 to both sides

-4x <56

Divide both sides by -4

Since we divided by a negative number, we must flip the inequality sign

x <-14

Flip the inequality sign

x> -14
