Answer:

<h3>The answer is option D.</h3>

Step-by-step explanation:

First we must first find the LCM

The LCM of x² + 3x + 2 and (x + 2)(x + 1 ) is

x² + 3x + 2

So we have

\frac{x}{ {x}^{2} + 3x + 2 }  -  \frac{1}{(x + 2)(x + 1)}  \\  \\  =  \frac{x - 1}{ {x}^{2} + 3x + 2 }

Hope this helps you

Simplify: (3a – 4b)(a + b). . A.. 3a2– ab – 4b2. . B.. 3a2 – 7ab – 4b2. . C.. 3a2 – 12ab – 4b2. . D.. 3a2 + ab – 4b2.
-Dominant- [34]
To simplify the expression, we distribute terms accordingly. It is done as follows:

<span>(3a – 4b)(a + b)
3a</span>² + 3ab -4ab -4b²
3a² - ab -4b²

Therefore, the correct answer is option A, <span>3a^2– ab – 4b^2. 

Hope this answers the question. Have a nice day. Please feel free to ask more questions.</span>

Find the slope intercept form.<br><br>passes through the points (4,3) and (7,-2)
11111nata11111 [884]

(\stackrel{x_1}{4}~,~\stackrel{y_1}{3})\qquad (\stackrel{x_2}{7}~,~\stackrel{y_2}{-2}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{-2}-\stackrel{y1}{3}}}{\underset{run} {\underset{x_2}{7}-\underset{x_1}{4}}} \implies \cfrac{-2 -3}{7 -4} \implies \cfrac{ -5 }{ 3 }

\begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{3}=\stackrel{m}{-\cfrac{5}{3}}(x-\stackrel{x_1}{4}) \\\\\\ y-3=-\cfrac{5}{3}x+\cfrac{20}{3}\implies y=-\cfrac{5}{3}x+\cfrac{20}{3}+3\implies y=-\cfrac{5}{3}x+\cfrac{29}{3}

Give the equation for each of the following statements.
emmasim [6.3K]

Answer:

Step-by-step explanation:

1. Y varies jointly as R and T

Y = k*R*T

Y = kRT

Where,

k = constant of proportionality

2. B is directly proportional to the square of A and inversely proportional to the cube of C.​

B = k(A²) / C³

B = kA²/C³

Where,

k = constant of proportionality

The gross federal debt y​ (in trillions of​ dollars) for a certain country in year x is approximated by the following​ equation,
miskamm [114]

Answer: 2008

Step-by-step explanation:

Given : The gross federal debt y​ (in trillions of​ dollars) for a certain country in year x is approximated by the equation y =1.18x +1.58 , where x is the number of years after 2000.

To find the year in which the federal debt will be $10.68 trillion, we substitute y= 10.68 in the above equation , we get

10.68 =1.18x +1.58\\\\\Rightarrow\ 1.18x=10.68-1.58\\\\\Rightarrow\ 1.18x =9.1\\\\\Rightarrow\ x=\dfrac{9.1}{1.18}=7.7118644067\approx8

The required year will be = 2000+8=2008.

Hence, in 2008  the federal debt will be $10.68 trillion.
