Answer:
B
Step-by-step explanation:
A. 37 isn't a number sentence
B. 49 + (-12) = 49-12. They're the same thing because 49 minus 12 can also be written as 49 plus negative 12
C. 49 + 12 doesn't equal 49-12
D. 12- 49 = -37 which isn't equivalent to 49-12.

Answer: See step by step. Replace the x with theta
Step-by-step explanation: Since sin is less than zero, and secant is positive. This means the trig values are in Quadrant 4.
We know that secФ=17/15. We need to find sin,cos,tan,csc, and cot.
We can find tangent by using the identity
where x is theta.



tan x=
, Tangent in the fourth quadrant is negative so the answer is instead

We can find cotangent by taking the recipocial of tan so

We can find cos by taking reciprocal of sec remeber that cosine is positive in 4th quadrant so the answer is

We can find sin by doing quoteint identies.



To find csc, take reciprocal of sine.

Answer: x is greater than or equal to 16
You have to have the same base numbers
2^4x = 2^7x
now you can cancel out the 2s and set the powers equal to each other.
4x= 7x
-11x = 0
x = 0???
im not 100% sure but i think this is what you do
