0.12 can be written as 12/100 or 3/25. It is very much a rational number as no square root is involved in the fractional form of the number.
The total to this would be $1,389.93 because $1,299 + 7% = $1,389.93
Answer:
c. f(x) x+1/x-1
Step-by-step explanation:
To answer this question, we need to check each answer one by one until we find the right one.
y = (x+6)/(x-6)
switch x and y
x = (y+6)/(y-6)
solve for y
x(y-6) = y+6
xy - 6x = y+6
y(x-1) = 6x+6
y = (6x+6) /(x-1) = 6(x+1)/(x-1)
f^-1(x) = 6(x+1)/(x-1)
y = (x+2)/(x-2)
switch x and y
x = (y+2)/(y-2)
solve for y
x(y-2) = y+2
xy -2x = y+2
y(x-1) = 2x+2
y = (2x+2)/(x-1)
f^-1(x) = 2(x+1)/(x-1)
y = (x+1)/(x-1) ------ correct one
switch x and y
x = (y+1)/(y-1)
solve for y
x(y-1) = y+1
xy - x = y+1
y(x-1) = x+1
y = (x+1)/(x-1)
f^-1(x) = (x+1)/(x-1)
f(x) = f^-1(x)
The value of x = -3/2 .
<h3>What is an Equation ?</h3>
An equation is a mathematical statement that relates unknown variable to constants to determine their value.
The equation given is
(2x+3 ) / 7 Divided by 1 = 0
2x +3 = 0
2x = -3
x = -3/2
Therefore the value of x = -3/2 .
The complete equation is
(2x+3)/7

The length of the rectangle is 0.25 or 1/4. This is because the area is equal to 5/8 or 0.625, and the width of the rectangle is 2 1/2 or 0.25. So 0.625/2.5 = 0.25 or 1/4.
