Confirm that f and g are inverses by showing that f(g(x)) = x and g(f(x)) = x.

charle [14.2K]

ANSWER

See below

EXPLANATION

Given

$f(x) = \frac{ {x}- 9 }{x + 5}$

and

$g(x) = \frac{ - 5x - 9}{x - 1}$

$(f \circ \: g)(x)= \frac{ (\frac{ - 5x - 9}{x - 1})- 9 }{(\frac{ - 5x - 9}{x - 1} )+ 5}$

$(f \circ \: g)(x)= \frac{ \frac{ - 5x - 9 - 9(x - 1)}{x - 1}}{\frac{ - 5x - 9 + 5(x - 1)}{x - 1} }$

Expand:

$(f \circ \: g)(x)= \frac{ \frac{ - 5x - 9 - 9x + 9}{x - 1}}{\frac{ - 5x - 9 + 5x - 5}{x - 1} }$

$(f \circ \: g)(x)= \frac{ \frac{ - 5x - 9x + 9 - 9}{x - 1}}{\frac{ - 5x + 5x - 5 - 9}{x - 1} }$

$(f \circ \: g)(x)= \frac{ \frac{ - 14x }{x - 1}}{\frac{ -14}{x - 1} }$

Since the denominators are the same, they will cancel out,

$(f \circ \: g)(x)= \frac{ - 14x}{ - 14} = x$

You need to buy 8 packages of meat for a cookout. A package of hot dogs costs $2.19 and a package of hamburgers costs $5.89. You

Daniel [21]

Answer:

1.89x + 5.19y = 31.62.

Step-by-step explanation:

Let the pagke of hot dags be x

Let the pakage of hamburgers be y

Now they total up tp 8 packages.

xEliminate the cost

x+y=8

y=8-x

Cost of hotdogs = $1.89

Cost of hamburgers = $5.19

1.89x+5.19y=31.62

1.89x+5.19(8-x)=31.62

1.89x+41.52-5.19=31.62

-3.3x=--9.9

x=3

y=8-3

y=5
