Answer:
(4,-8)
Step-by-step explanation:
Plug in the answers for the equations.
So if you want it to be 9 less than your number (x) then you would subtract nine.
So it would be:
x - 9.
So if your "number" is 12 then you would substitute x for 12 and it would be 12-9. The answer is 3. So 3 is 9 less than a number (12).
I believe
Area=length*height
Area=(25)*(8)
Area=200 feet^2
When the radius is 8, the area would be 201.06
Area of circle = pi x radius² (pi x 8²)
original quantity : 10 for $1
new quantity: 4 for $1
now we have to find each percent change
10-4=6
6÷100=0.06
0.06=6%
the quantity went down 6%
