Answer:
Step-by-step explanation:
The given trigonometric equation is
for 
.
We divide through by 5 to get;
We take the inverse tangent of both sides to obtain;
Since the tangent ratio is positive, it means 
could also be in the 3rd quadrant. But this is outside the given range.
Therefore the correct answer is A
Rotation counterclockwise 90 degrees has the rule
(x,y) -> (-y,x)
So the image is obtained, according to the rule,
(2,3) -> (-3,2)
Answer: no
Step-by-step explanation:
algebraic expression for "a number , n, divided by 4 is 4. I
put 3 into 15 than put 6 into 15 then the answer u get from putting 6 into 15 subtract that by 2 and the answer u get from the u multpy the answer that u got from putting 3 into 15 together
Answer: -89
Step-by-step explanation:
So your equation is
- 9(a) - 7(x) - 9(c) - 9(b) - 7(y)
You know that (a) (b) and (c) = -1
You also know that (x) and (y) = 7
So, when you put this into the equation, it will look like this:
- 9(-1) - 7(7) - 9(-1) - 9(-1) - 7(7)
When you work that out you will get left with your answer, which is -89.
HOPE THIS HELPS!!!
