Lets take 6/9. 9 is a multiple of 27, multiply 9 times 3 for a denominator of 27. Whatever we to do the bottom, we do to the top. So multiply 6 by 3 as well for numerator of 18. This gives us our answer, 18/27.

Answer: 18/27

Step-by-step explanation: 9 times 3 is 27. To multiply, you have to multiply both the top and the bottom to identify the final answer.

$\bf \stackrel{x-intercept}{(\stackrel{x_1}{2}~,~\stackrel{y_1}{0})}\qquad \stackrel{y-intercept}{(\stackrel{x_2}{0}~,~\stackrel{y_2}{6})} \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{6-0}{0-2}\implies \cfrac{6}{-2}\implies -3 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-0=-3(x-2)\implies y=-3x+6$

-7x - 12 = - 7х + 3(-4 - x)

dsp73

Answer:

$x=0$

Step-by-step explanation:

$-7x - 12 = - 7x + 3(-4 - x)$

Open up the parentheses

$-7x - 12 = - 7x -12-3x$

-7x cancels out on both sides

$-12 =-12-3x$

-12 cancels out on both sides

$0=-3x\\x=0$

I hope this helps!

State if the given functions are inverses. f(x) = 1/x + 3 g(x) = 4/x + 2

Stolb23 [73]

Answer:

they are not inverses

Step-by-step explanation:

f(1) = 1/1 +3 = 1 +3 = 4

g(4) = 4/4 +2 = 1 +2 = 3 ≠ 1

If the functions were inverses, we would have g(f(1)) = 1, which we do not.

The given functions are not inverses.

_____

The same would be true if your functions were

f(x) = 1/(x+3) and g(x) = 4/(x+2)

f(1) = 1/(1+3) = 1/4

g(1/4) = 4/(1/4 +2) = 4/(9/4) = 16/9 ≠ 1
