Answer:
The correct answer is d) the ratio of the change in y to the change in x along the line.
We can tell this by looking at the slope formula.
m (slope) = (y2 - y1)/(x2 - x1)
Answer:
I'm not sure what the answer is but, I'm thinking the answer w
Answer:
Center (-2 , 4)
Step-by-step explanation:
x^2 + 4x + y^2 - 8y = - 11
(x^2 + 4x + (4/2)^2 + (y^2 - 8y + (8/2)^2 ) = - 11 + 4 + 16
(x + 2)^2 + (y - 4)^2 = 9
Center (-2, 4)
Answer:
7.
I) must be true
II) 1 - 1 < 2 - 4 --> false
III) (-10)*(-10) < 1*1 --> false
IV) 1/2 < 2/10 --> false
So (B) 1 must be true
8.
x!·(x + 1)!/2 = (x + 1)!^2 / (2·(x + 1)) = (17 + 1)!^2 / (2·(17 + 1)) = 18!^2 / 6^2
(D)
9.
2·√3·6 = √((2·√3)^2 + 6^2)·h --> h = 3 --> (C)
