Answer:
That is wrong graph, pls show the other ones
Both Lines need to cross each other 1 time to have one solution.
Answer:
x²y² - z²
Step-by-step explanation:
Note that
(xy + z)(xy - z) are the factors of a difference of squares
a² - b² = (a + b)(a - b)
here a = xy and b = z, thus
(xy + z)(xy - z) = (xy)² - z² = x²y² - z²
48
1st seat 6 possible for each 6 only 1 possible(spouse) for seat 2
3rd seat 4 possible for each 4 only 1 possible(spouse) for seat 4
5th seat 2 possible for each 2 only 1 possible(spouse) for seat 6
6 x 4 x 2 = 48
OR 3 couples possible arrangements 3 x 2 x1 = 6
each couple 2 possible 2 x 2 x 2 = 8
therefore 6 x 8 = 48
Answer:
D. 
Step-by-step explanation:
We want to find the distance between (-6, 4) and (-8, 6).
First, we find the difference:
d = (-8 - (-6), 6 - 4)
d = (-8 + 6, 2)
d = (-2, 2)
We now find the magnitude:
where x = x coordinate, y = y coordinate
The answer is Choice D.
<u>GEOMETRIC :</u> Only 1 straight line can pass through two distinct points simultaneously.
<u>NONSENSICAL :</u> Infinite lines can pass through two distinct points to be exact - (2*Infinite - 1)
Explanation.
Let the points be A and B
A can have infinite lines pass through it
B can have infinite lines pass through it
A & B together has one line pass through them
A+B = A + B - (A&B) = Inf + Inf - 1 = 2*Inf - 1 (Approx Inf).
