Answer:she incorrectly transformed the equation standard form
Step-by-step explanation:
First you need to combine like terms
13x+8-15x=6+x+11
-2x+8=x+17
-x -8 -x -8
-3x=9
--- ----
-3 -3
x=-3
I hope I've helped!
The equation is y = 250(0.89)^x and the decay rate is 11%.
<h3>How to calculate the values?</h3>
The initial value will be:
= 250(0.89)^x
= 250(0.89^0)
= 250
The decay rate will be:
= 1 - 0.89
= 0.11
= 11%
In conclusion, the equation is y = 250(0.89)^x and the decay rate is 11%.

Answer:
with exponents, you take a number and multiply it by itself.
Step-by-step explanation:
the root of a number is the number that can be multiplied a certain amount of times to get us that number.
therefore roots get you to the root of a number.

I believe the answer would be 198.54
First, find the circumference of the circle which for a diameter of 25, would be roughly 78.54 (according to goo gle) and the equation for circumference, C= πd
Then, add the 120, because of the rectangle in between the two half circles.
So my thought process was find the circumference, assuming that it was a full circle because it has two halves of a circle on either end. Then after that, you would add the two sides of the rectangle that contribute to the size of the perimeter
Please correct me if Needed and have a good day!
