No, they forgot to switch variable labels after solving for the independent variable...
y=-8x+4
y-4=-8x
(y-4)/-8=x
Now that you have solved for the independent variable x, you switch the variable labels...
y=(x-4)/-8
f^-1(x)=(x-4)/-8 which should really be rewritten as:
f^-1(x)=(4-x)/8 :P
Step-by-step explanation:
no of days = (15×12)/20= 9 days

Explanation:
The triangle is a right triangle if the lengths of its sides satisfy the Pythagorean theorem: <em>if the square of the length of the longest side is equal to the sum of the squares of the lengths of the other two sides</em>.
$403.75
Step 1: 415(.15)
Step 2: 475 - 415(.15)
Step 3: 403.75
A line parallel to y = 2/3 x - 5 will have a slope of 2/3.
The equation of a line passing through (-6, -1) with a slope of 2/3 is
y - (-1) = 2/3 (x - (-6))
