Answer:
Y = 1/27x
Step-by-step explanation:
In order to find the inverse we switch places with x and y to get x = y27. In order to even out the equation, we divide both sides by 27 to get our answer. The answer would be y = x/27 or y = (1/27)x.
Apologies if I'm incorrect.
Answer:
Sales of trench coats increased 8.3 percentage points faster than total coat sales.
Step-by-step explanation:
<u>2006:</u>
top coats is 297,
parkas is 210,
jackets is 213,
raincoats is 137,
trench coats is 103
Total: 
<u>2007:</u>
topcoats is 223,
parkas is 210,
jackets is 285,
raincoats is 259,
trench coats is 127
Total: 
<u>Percent increase in total sales:</u>

<u>Percent increase in sales of trench coats:</u>

Since
sales of trench coats increased 8.3 percentage points faster than total coat sales.
Y=9x-2
3x-2y=7
3x-18x+4=7
-15x=3
x=-1/5
y= -19/5
Let x represent the larger number.
1/(x -28) +4/x = 1/6
Multiplying by the product of denominators, we have
6x +24(x -28) = x(x -28)
In standard form, this is
x^2 -58x +672 = 0
(x -42)(x -16) = 0
The two numbers are (-12 and 16) or (14 and 42).
