Use the Pythagorean theorem. The Pythagorean Theorem uses the following formula:

Plug in the known values into the equation:



Subtract both sides by 36.

Square root both sides to get b by itself.


The value of x is 8.
Answer:
decreasing
Step-by-step explanation:
since its negative it will slope down
You would subtract x from each side. It would then be 3y=-x-15. Then you would divide all of the equation by 3. Your final answer would be y=-3x-5.
Answer:
a=9
divide 81 by 9 on both sides and you get 9.
