Answer:
C
Step-by-step explanation:
Everything else can be simplified to 2/5, except for 9/20
Answer:
Step-by-step explanation:
If you factor the first one you get 
The 6x times 5 gives 30x, added to 30x, the middle term so it works.
For the 2nd one you know the factoring has to be 
so its easy to multiply to get 48x as the middle term.
-69>22 or 224 is what I think the answer is not too sure
Answer:
C, (6,4)
Step-by-step explanation:
The points (x,y) that lie on the line must fit into the equation correctly. So, we can test out the 4 options to see whether they fit correctly into the equation.
A:
y-4
= -4 -4 = -8
-2(x-6)
= -2 (-6-6)
= 24
Since -8≠24, so A is incorrect.
B:
y -4 = -6-4 = -10
-2(x-6) = -2 (-4-6) = 20
-10≠20, so B is incorrect.
C:
y-4 = 4 -4 = 0
-2(x-6) = -2(6-6) = 0
Both sides are equal. C is correct.
But lets test D out too.
y-4 = 6-4 = 2
-2(x-6) = -2(4-6) = 4
2≠4, so D is incorrect.
