Answer:
Step-by-step explanation:
- 2/3x - 9 - 2x + 2 = 1
- 2/3x - 2x - 7 = 1
- 2/3x - 6/3x - 7 = 1
- -4/3x - 7 = 1
Correct option is B
Since beta is in the first quadrant, the final answer will be positive.
To find cos(beta) so we can use the half angle identity, we can substitute into the Pythagorean identity. Doing so gives us that

So, this means that

Observing there is a difference of +8 between each f(x).
The slope of this sequence is 8.(y2-y1)/(x2-x1)
Using the point slope equation,
y-y1 = m(x-x1) yields
y = 8x -4 as the answer.
Answer:
B. 4
