<h2>
Stella is correct about center and wrong about radius </h2>
Step-by-step explanation:
Equation of circle with (h,k) as center and radius r is given by,
(x-h)²+(y-k)² = r²
Here equation is
x²−8x+y²+2y=5
Changing in to (x-h)²+(y-k)² = r² form
x²−8x + 16 - 16 +y²+2y+1 - 1=5
(x-4)² - 16 + (y+1)² -1 = 5
(x-4)² + (y+1)² = 22
(x-4)² + (y+1)² = 4.69²
Center is (4,-1) and radius is 4.69
Stella is correct about center and wrong about radius
Answer:
x=10, y = -20
Step-by-step explanation:
y = –5x + 30
x = 10
Substitute the second equation into the first
y = –5*10 + 30
y = -50 +30
y = -20
x=10, y = -20
Answer:
i think 1
remember like this: y=mx+b
m is slope
b is y intercept
Answer:
Square is a kind of kite.
Step-by-step explanation:
Consider the provided information.
Kite is a flat shape with two pairs of sides and each pair is made of two adjacent sides that are equal in length.
Square has four equal sides and four equal angles of 90°
Square is a kind of kite because it has two pairs of equal adjacent side.
Hence, square is a kind of kite.
Hello from MrBillDoesMath!
Answer:
Slope = 4/5
Discussion:
Slope = (change in y) / (change in x)
Slope =
(1-5)/(0-5) =
-4/-5 =
4/5
Thank you,
MrB
