Answer:
Step-by-step explanation:
Given
x^2 + y^2 - 16y - 36 = 0
x^2 + y^2 - 16y = 36
x^2 + y^2 - 16y + (16/2)^2 = 36 + 8^2
x^2 + (y - 8)^2 = 64 + 36
x^2 + (y - 8)^2 = 100
The center is at (0,8) and the radius is 10
Try and follow it from the graph below.
Answer:
Use the completing the square method
which is
(x+ (b/2))^2 - (b/2)^2 + c
x^2+6x+8 = 0
a = 1 b = 6 c = 8
b/2 = 3
(x+3)^2 - 9 + 8 = 0
becomes
(x+3)^2 -1 = 0
which becomes
(x+3)^2 = 1
ADDITIONAL:
i don’t know why they said (x-h) since there are no negatives in this
let me explain
(x-h) ^2 is the same as (x-h)(x-h) which leaves us with
x^2 - 2xh + h
but the equation we start with is
x^2 + 6x + 8 = 0
look at the signs
the middle term’s one is different
Answer:
Triangles MNO and DEF could not be similar.
Step-by-step explanation:
The multiplier for triangle JKL is 3, so it is similar. The multiplier for GHI is 2, so it is similar.
