Answer:

Step-by-step explanation:
To solve, we need to take square root of both sides first:

Now we use the property of radical shown below to simplify square root of 28:
Property: 
Now, we have:

Now we take 4 to the other side and isolate x:

first answer choice is right.
Answer:
the price decreased by 7.06 percent
Step-by-step explanation:
100/354x329=92.93785311
100-92.93785311=7.06
If you want to solve that put it in the formula to find the slope
M=
Y1-y2
---------
X1-x2
And plug that into slope int form with one of the points to find the y int/ b value and then your have ur equ
Start at (0, 72), then (1, 64), (2, 56), ETC. I hope you see the pattern! Do it until you reach (9, 0)
