3,100= 1,900 +84x
right since 84 months in 7 years
so 14.3% right?

Answer:
-2/5
Step-by-step explanation:
you have to do y2-y1 and x2-x1
The correct answers are B and D.
A is false because, even though it's true that 4 points are not necessarily on the same line, it is not required that they are collinear in order for them to be coplanar.
B is true: two points always lie on the same line (and thus also in infinite same planes), but four points are not always coplanar
C is false. As a counterexample pick the four points (0,0, 0), (1, 0, 0), (0, 1, 0), (0, 0, 1).
D is true: two points are always on the same line, three points always lie in a common plane, but 4 points are not necessarily coplanar.
Answer:
Y=√2
Step-by-step explanation:
We can use the pathagorian theorum: A²+B²=C² now in this case it would be X²+Y²=2² we also know that X and Y are the same number in this problem because they have the same corresponding angle (triangle angles always add to 180 and since we know 2 of the angles are 45 and 90 the remaining angle will also be 45) Because of this we can change our equation to Z²+Z²=2² (I'm using Z so that we do not confuse it with another letter we've already used) from there we can go to Z∧4=2² and then we will solve the equation. Z=√2 Z also equals X and Y therefore Y=√2
I hope this helps and please let me know if there is anything you don't understand I would be happy to clarify!
