Hi there!
Finding the equivalen ratio means to find a equivalent numbers that’s equivalent to 6 and 7 which also means a number that 6 and 7 all goes into...
6,12,18,24,30,36,42
7,14,21,28,35,42
Final Result: 42
C...to show this, interchange letters: x = (y+1)/(y-1)xy-x = y + 1xy - y) = x + 1y(x-1) = x+1y = (x+1)/(x-1) ⇐ this is f-1(x) and it's identical to f(x). Note: <span>the equal sign is missing in the definitions of the functions c. & d.</span>
The answe to this question is 0.133333333
Supplementary angles add up to 180 degrees, so look for two angles by each other that add up to 180 degrees.
Hope this Helps!
