Answer:
Step-by-step explanation:
For problem #1 identify the coordinates of the point of intersection of the two lines. This point is (4, 2), and this is the solution to #1.
In problem #2 the lines never cross, and thus we conclude that there is no solution.
The center would be at (-5,-8)
Hope this helps :)
Answer:
The center (2,6) and the radius is 8
Step-by-step explanation:
The equation of a circle is (x-h)^2 + (y-k)^2 =r^2
where (h,k) is the center of the circle and r is the radius
We have
(x-2)^2 + (y-6)^2 =64
(x-2)^2 + (y-6)^2 =8^2
The center (2,6) and the radius is 8
Think of it as (24x)^1/2 then use chain rule. Which means first derive (24x)^1/2 as deriving u^1/2 (substitute u for 24x), then deriving 24x, finally write those 2 derivatives as a multiplication (as in a*b).
