Answer:
1/8
Step-by-step explanation:

Since we are translating this graph one unit to the right, replace x with (x-1)
Note: If you are translating a graph to the left by k units, replace x with (x+k), and if by the right, replace x with (x-k)

After simplifying, we now have the following equation:

This is the new equation. Let me know if you need any clarifications, thanks!
angle for triangle is 180°
angle ACB is 75° because it has mention that is an isosceles triangle
So that angle of BAC is 180°-75°-75°=30°

Short answer: 0.69Take 100. 31% = 31, 100-31=69Of course, when you increase the result by 31 percent you do not get the 100 back. But that was not the question.But, for completeness what do I multiply by to get the number, when adding 31 percent, gives me the original number, it is 0.7633 (1/1.31)

Your measure start at 16. So that is the basis (unless stated otherwise) upon which you reference the change.
That is:
16
20−16
is you fraction.
This gives:

For this to be a percentage we need the denominator such that it becomes 100. Thus we have:
