Idk if you wrote it incorrectly. but im just going to avoid the first 5× soooo x= -1
One day, a girl named,"Amanda" wanted to share cookies in between 3 of her best friends.However, she only had 1/2 of her cookie left. So she divided her cookie by 3 to share her cookie with every single friend.
We want to find 
such that the object needs is in equilibrium:
We're told that 
, 
, and 
. We also know the angle between 
and 
is 95º, which means
is perpendicular to both and , so 
.
If we take the dot product of with the sum of all four vectors, we get
We can do the same thing with and :
Finally, if we do this with , we get
Answer:
-7 (7x^2-y^2-19)
Step-by-step explanation:
Hello.
A direct variation is when one variable affects the other variable. Let's take a look at each table that we've been given.
Table 1:
x = 1, y = 19
x = 2, y = 38
x = 3, y = 57
This table seems to have the effect of when x goes up by 1, y goes up by 19;
1, 19; 2, 38; 3, 57; and so on.
This means at least table 1 has a direct variation with it's variables. But let's continue with table 2 as we have answer choices that say both, neither, or individual tables have direct variations.
Table 2:
x = 5, y = 48
x = 6, y = 72
x = 7, y = 84
This doesn't appear to have a constant direct variation, aside from the first two sets of variables.
This leaves us with our answer:
A.) Table 1 only
I hope this helps!
