Answer:

$x=1$

Step-by-step explanation:

Given:

$3x-1=2x$

Taking the terms of 'x' to one side and the constants to the other side.

$3x-2x=1$

$x=1$

So, the value of 'x' is 1 for the given equation.

12) Write the equation of a rational function

aev [14]

Answer:

$\frac{4(x - 5)(x + 7)(x - 12)}{(x + 1)(x)(x - 12)}$

Step-by-step explanation:

A rational function is

$\frac{p(x)}{q(x)}$

where q(x) doesn't equal zero.

If p is a asymptote, or hole at that value, then we will use

$(x - p)$

Step 1: We have asymptote as 0 and -1 so our denomiator will include

$(x - 0)(x - ( - 1)$

Which is

$(x)(x + 1)$

So our denomator so far is

$\frac{p(x)}{x(x + 1)}$

Step 2: Find Holes.

Since 12 is the value of the hole,

$(x - 12)$

is a the binomial.

This will be both on the numerator and denomator so qe have

$\frac{(x - 12)}{x(x + 1)(x - 12)}$

Step 3: Put the x intercepts in the numerator.

Since 5 and -7 is the intercepts,

$\frac{(x - 12)(x - 5)(x + 7)}{x(x + 1)(x - 12)}$

Step 4: Horinzontal Asymptotes,

Multiply the numerator and denomiator out fully,

$\frac{ {x}^{3} - 10 {x}^{2} - 59x + 420 }{ {x}^{3} - 12 {x}^{2} + x - 12}$

Take a L

look at the coefficients,

Notice they have the same degree,3, this means if we divide the leading coefficents, we will get our horinzonral asymptote.

Multiply the numerator by 4.

$\frac{4(x - 12)(x - 5)(x - 7)}{x(x + 1)(x - 12)}$

Above is the function,

If f(x) = 7 + 4x and g(x)=1/2x, what is the value of (f/g)(5)?

Romashka [77]

<h2>Answer:</h2>

$d. \ \boxed{270}$

<h2>Step-by-step explanation:</h2>

In this exercise we need to make a division and evaluate the new function at $x=5$ . so we have two functions, namely:

$f(x)=7+4x \ and \\ \\ g(x)=\frac{1}{2x}$

Therefore:

$f(5)=7+4(5)=27 \\ \\ g(5)=\frac{1}{2\times 5}=\frac{1}{10}$

So:

$(f/g)(5)=\frac{27}{\frac{1}{10}}=270$
