Answer
C. (5/2, -1/3)
Step by step explanation
Here we use the rational root theorem.
The possible roots are
+1, +3, +5, +15, +1/2, +3/2, +5/2, +15/2, +1/3, +5/3, +1/6 and +5/6
We have to use the synthetic division to find the correct root of this function.
Here the roots are 5/2 and -1/3
Others are not roots of this function.
Let's check x = 5/2 with synthetic division.
5/2) 6 -13 13 -39 -15
- 15 5 45 15
--------------------------
6 2 18 6 0
Similarly x = -1/3 is also root of this function.
Answer: C. (5/2, -1/3)

Answer:
y=5
x=7
Step-by-step explanation:
When given an expression in the form a⁻ᵇ the expression is the same as 1/aᵇ where a and b are integers.
Solving the question by giving the equivalents of the expression:
Therefore (-j)⁻⁷ is the same as 1/j⁷
The value of x=7
k⁻⁵+m⁻¹⁰=1/k⁵+1/m¹⁰
Therefore the value of y is 5.
Cot x = cos x csc x
1/tan x = cosx (1/sin x)
1/(sin x / cos x) = cos x / sin x
cos x / sin x = cos x / sin x
The domain of validity is all real number values of x except for sin x = 0.
