Doss [256]

Answer:

Step-by-step explanation:

3/12 really is 1/4  (Divide top and bottom by 3) 3/3 = 1 and 12/3 = 4

1/5 + 1/4 = 4/20 + 5/20 = 9/20

There is something we don't know about this question. If you put a remark, I will come back and look at it.

How do you solve these equations? I don't want you to answer all of them, just tell me how to solve each type of equation on the
miss Akunina [59]

Answer:

8. Identify the common denominator; express each fraction using that denominator; combine the numerators of those rewritten fractions and express the result over the common denominator. Factor out any common factors from numerator and denominator in your result. (It's exactly the same set of instructions that apply for completely numerical fractions.)

9. As with numerical fractions, multiply the numerator by the inverse of the denominator; cancel common factors from numerator and denominator.

10. The method often recommended is to multiply the equation by a common denominator to eliminate the fractions. Then solve in the usual way. Check all answers. If one of the answers makes your multiplier (common denominator) be zero, it is extraneous. (10a cannot have extraneous solutions; 10b might)

Step-by-step explanation:

For a couple of these, it is helpful to remember that (a-b) = -(b-a).

<h3>8d.</h3>

\dfrac{5}{x+2}+\dfrac{25-x}{x^2-3x-10}=\dfrac{5(x-5)}{(x+2)(x-5)}+\dfrac{25-x}{(x+2)(x-5)}\\\\=\dfrac{5x-25+25-x}{(x+2)(x-5)}=\dfrac{4x}{x^2-3x-10}

___

<h3>9b.</h3>

\displaystyle\frac{\left(\frac{x}{x-2}\right)}{\left(\frac{2x}{2-x}\right)}=\frac{x}{x-2}\cdot\frac{-(x-2)}{2x}=\frac{-x(x-2)}{2x(x-2)}=-\frac{1}{2}

___

<h3>10b.</h3>

\dfrac{3}{x-1}+\dfrac{6}{x^2-3x+2}=2\\\\\dfrac{3(x-2)}{(x-1)(x-2)}+\dfrac{6}{(x-1)(x-2)}=\dfrac{2(x-1)(x-2)}{(x-1)(x-2)}\\\\3x-6+6=2(x^2-3x+2) \qquad\text{multiply by the denominator}\\\\2x^2-9x+4=0 \qquad\text{subtract 3x}\\\\(2x-1)(x-4)=0 \qquad\text{factor; x=1/2, x=4}

Neither solution makes any denominator be zero, so both are good solutions.

\bf f(x)=log\left( \cfrac{x}{8} \right)\\\\&#10;-----------------------------\\\\&#10;\textit{x-intercept, setting f(x)=0}&#10;\\\\&#10;0=log\left( \cfrac{x}{8} \right)\implies 0=log(x)-log(8)\implies log(8)=log(x)&#10;\\\\&#10;8=x\\\\&#10;-----------------------------

\bf \textit{y-intercept, is setting x=0}\\&#10;\textit{wait just a second!, a logarithm never gives 0}&#10;\\\\&#10;log_{{  a}}{{  b}}=y \iff {{  a}}^y={{  b}}\qquad\qquad &#10;%  exponential notation 2nd form&#10;{{  a}}^y={{  b}}\iff log_{{  a}}{{  b}}=y &#10;\\\\&#10;\textit{now, what exponent for "a" can give  you a zero? none}\\&#10;\textit{so, there's no y-intercept, because "x" is never 0 in }\frac{x}{8}\\&#10;\textit{that will make the fraction to 0, and a}\\&#10;\textit{logarithm will never give that, 0 or a negative}\\\\&#10;

\bf -----------------------------\\\\&#10;domain&#10;\\\\&#10;\textit{since whatever value "x" is, cannot make the fraction}\\&#10;\textit{negative or become 0, , then the domain is }x\ \textgreater \ 0\\\\&#10;-----------------------------\\\\&#10;range&#10;\\\\&#10;\textit{those values for "x", will spit out, pretty much}\\&#10;\textit{any "y", including negative exponents, thus}\\&#10;\textit{range is }(-\infty,+\infty)

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




now on 2)

\bf f(x)=\cfrac{3}{x^4}   if the denominator has a higher degree than the numerator, the horizontal asymptote is y = 0, or the x-axis,

in this case, the numerator has a degree of 0, the denominator has 4, thus y = 0


vertical asymptotes occur when the denominator is 0, that is, when the fraction becomes undefined, and for this one, that occurs at  x^4=0\implies x=0  or the y-axis

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


now on 3)

\bf f(x)=\cfrac{1}{x}


now, let's see some transformations templates

now, let's take a peek at g(x)
