Answer:
center: (-10,-4)
radius: 9
Step-by-step explanation:
Let's start off by moving the 35 to the other side and grouping the x and y terms we have
(x²+20x)+(y²+8y)= -35
Next we take the term with the x coeficcent, divide it by 2, and square it
so
for the x we would do (20/2)²=100
and make sure we add that to the 35
(x²+20x+100)+(y²+8y+16)= -35+100+16
next factor everythign to get
(x+10)²+(y+4)²=81
therefore the center is (-10,-4)
and the radius is √81 or 9

Answer:
30/80 is the fraction of decrease. Converting this to a fraction with a denominator of 100, we get the fraction;
37.5/100
Now we just take the numerator of the number to get the percent, which is the solution.
37.5%
since the original price was ninety we have to multiply 5/6 by 90
90/1(5/6)
=450/6
=75
