Answer:
Option B.(4,-4)
Step-by-step explanation:
we know that
1) An angle 45 degrees means that the absolute value of the x-coordinate of the point on the terminal side is equal to the absolute value of the y-coordinate of the point on the terminal side
2) An angle of -45 degrees lies on the IV Quadrant
That means------> The x-coordinate is positive and the y-coordinate is negative
therefore
The point on the terminal sides of -45 degrees is the point (4,-4)
Let's look at the second equation and try multiplying it by 4:
4 * (3x + ky) = 4 * 27
Which gives us:
12x + 4ky = 108
This looks almost exactly like the first equation except that instead of -20y, there is 4ky. We could try making them equal to each other and solving for k:
-20y = 4ky
-20 = 4k
k = -5
Then, the answer is k = -5.
Answer:
An axiom is often a statement assumed to be true for the sake of expressing a logical sequence. ... These statements, which are derived from axioms, are called theorems. A theorem, by definition, is a statement proven based on axioms, other theorems, and some set of logical connectives.

Answer:
8 is the correct answer because coefficient lies before Exponent. Exponent is variable
So 8 is the coefficient.
