Answer:
2
Step-by-step explanation:
The graphs intersect at 2 points.
The 2 solutions are x = -2 and x = 6.
Answer:
Since 6X2 + 6Y2 = 13 xy
-- 6X2 / XY + 6Y2/XY =13
---> 6 X/Y + 6 Y/X =13
6a + 6/a =13
---> 6a2 + 6 =13a
---> 6a2 -13a +6 =0
---> 6a2 -9a - 4a +6 =0
---> (2a-3) (3a-2) =0
2a-3 = 0
a= 3/2
So the Ratio will be = 3:2
Answer:
b = 45 / 4 = 11 1 /4.
Step-by-step explanation:
We are dealing with a (30,60,90)-triangle, therefore z = 15 sqrt(3) / 2. So as well b = (15 sqrt(3) / 2) sqrt(3) / 2 = 45 / 4.
