Is there a picture we can see if it’s a whole pie than 1/2
Answer: 56.4102564% decrease
Explanation: First determine whether the number is increasing or decreasing. Since it changes from 39 to 17, it's going down so it's decreasing.
Now to find the percent decrease,
we divide the amount of change by the original number.
The amount of change is the difference between the two numbers
which in this case is 39 - 17 and the original number is 39.

39 - 17 is 22 so we're left with
which gives us 56.4102564
Remember however that our problem is asking for a <em>percent</em>, not a decimal. So we need to write 56.4102564 as a percent by moving the decimal point 2 places to the right to get 56.4102564.
So when a number changes from 39 to 17, it has decreased by 56.4102564%.
The "rule" being described here is nothing more than the input/output of a mathematical function.
For every input 'x' value supplied, you only need to subtract three to it. For every input 'y' value, you only need to add four to it.
Example: I'll use variable 'm' to represent this function. Variable 'p' will represent the current input point.
m(p) = p[x - 3, y + 4] = p[-7 - 3, 0 + 4] = p[-10, 4]. 'p[]" is just the point.

Answer:
2a^2b^4
Step-by-step explanation:
Substitution.
Here is an example.
Let x be equal to 3 and y equal to 3.

From this we can conclude that the values of both x and y are equal to three therefore x and y have the same value and are equal.

Here in your case we have:
