Answer:
Step-by-step explanation:
-7x²=-448
x²=64
x=±8
Answer:
y=1, so (0, 1)
Step-by-step explanation:
Just subtract 3 from -2. Since there is no x in the problem, it means that this line is horizontal, meaning that the x can change but the y has to stay at 1.
The line is horizontal so there is no vertex point
Answer : option B
Given: center (4,2), vertex (9,2), and focus (4+2sqrt5,2)
The distance between vertex and center is 9-4 = 5
Center is (h,k) so h= 4 and k =2
focus is (h+c,k)
From the given focus (4+2sqrt5,2), c= 2sqrt(5)
Standard form of equation is

h= 4, k=2, a=5, c=2sqrt(5), we need to find out b




b^2 = 5
plug in all the values


Option B is correct
