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:
y=2x-6

There were 296 kids started at the beginning of the year
Answer is A.
The values of x must be greater than or equal to 1 and the value of x must be less than or equal to -2.
x >= 1.....x <= -2

You want to find out how many cups of flour Jaylin needs to make 30 biscuits.
We currently know 2 cups of flour makes 20 biscuits.
We can halve the recipe down to make it simplier - simply divide all ingredients by 2 to halve it.
1 cup of flour = 10 biscuits
Since 1 cup of flour equals 10 biscuits, and 2 cups of flour equals 20 biscuits, we can safely say 3 cups of flour equals 30 biscuits.
