X=-b/2a=4/14=2/7
Plug this value back into the function to find the corresponding Y value
Answer:
108
Step-by-step explanation:
16-10=6in2
Answer:
± 5
Step-by-step explanation:
= 5 or - 5 , written ± 5 ( ± plus or minus )
Since 5 × 5 = 25 and - 5 × - 5 = 25
The true question should be like this:
<span>What is the center and radius of the following circle: x^2 + (y _ 6)^2 = 50,
circle quation formula is (x-a)^2 + (y-b)^2 = R², so by identifying each term, we find </span>(x-a)^2=x^2 = (x-0)^2, (y-b)^2= (y _ 6)^2, R² = 50, implies R =5sqrt(2),
it is easy to identify that the center is (a,b)= (0, 6)
the radius is R =5sqrt(2),
