I believe the first and last one are polynomials. Usually they start with the highest exponent first and then work their way down.
Answer:
type=positive
Correlation refers to the degree of correspondence or relationship between two variables.
The answer is A. The Associative Property, followed by the Associative Property.
It's because they want you to group stuff, not simplify them.
A. x = 7, y = 4, z = 3
How?
Just plug in the numbers.
7 + 4 + 3 = 14
11 + 3 = 14
14 = 14
Next.
4 + 3 = 7
Next.
3 = 3
Plugging it in, we get (3)(2)+2y=-12 and 6+2y=-12. Subtracting 6 from both sides, we get -18=2y and dividing by 2 we get y=-9 to get (2, -9) since x is first in the pair
