Alyssa's company makes a profit of $175,000.

miskamm [114]

So the initial profit is 175000
If it falls by 25000 per month, this is 25000m
175000-25000m
(Insert the 5)
175000-25000(5)= 50,000

So the net profit after 5 months is $50,000

Hope this helps!

A. Use composition to prove whether or not the functions are inverses of each other. B. Express the domain of the compositions u

Kryger [21]

Given: $f(x) = \frac{1}{x-2}$

$g(x) = \frac{2x+1}{x}$

A.)Consider

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

$f(\frac{2x+1}{x} )=\frac{1}{(\frac{2x+1}{x})-2}$

$f(\frac{2x+1}{x} )=\frac{1}{\frac{2x+1-2x}{x}}$

$f(\frac{2x+1}{x} )=\frac{x}{1}$

$f(\frac{2x+1}{x} )=1$

Also,

$g(f(x))= g(\frac{1}{x-2} )$

$g(\frac{1}{x-2} )= \frac{2(\frac{1}{x-2}) +1 }{\frac{1}{x-2}}$

$g(\frac{1}{x-2} )= \frac{\frac{2+x-2}{x-2} }{\frac{1}{x-2}}$

$g(\frac{1}{x-2} )= \frac{x }{1}$

$g(\frac{1}{x-2} )= x$

Since, $f(g(x))=g(f(x))=x$

Therefore, both functions are inverses of each other.

B.

For the Composition function $f(g(x)) = f(\frac{2x+1}{x} )=x$

Since, the function $f(g(x))$ is not defined for $x=0$ .

Therefore, the domain is $(-\infty,0)\cup(0,\infty)$

For the Composition function $g(f(x)) =g(\frac{1}{x-2} )=x$

Since, the function $g(f(x))$ is not defined for $x=2$ .

Therefore, the domain is $(-\infty,2)\cup(2,\infty)$

What is the distance between the coordinates (9, 3) and (-8, 3)?

den301095 [7]

Answer:

17

Step-by-step explanation:

The y-value, 3, doesn't change, so you just take the absolute value of -8, 8, and add it to 9, 8 + 9 = 17

Which expression is equivalent to 4(12+5)+3?

AVprozaik [17]

Answer:

I think it is 17/85

Step-by-step explanation:

1/5. = 2/10. = 3/15. = 4/20. = 5/25. = 6/30. = 7/35. = 8/40. = 9/45. = 10/50. = 11/55. = 12/60. = 13/65. = 14/70. = 15/75. = 16/80. = 17/85
