<em>Answer: choice D.</em>
Step-by-step explanation:
<u>Trigonometric Functions</u>
We need to recall some properties and definitions of the trigonometric functions.


We need to simplify the following expression:

Substituting the identity for the secant:

Operating:

Substituting the definition of the tangent:

Correct choice D.
Answer: It has no solution.
Step-by-step explanation:
3x - 12 - 4 = 3x + 4 - 4
3x - 8 = 3x
3x - 8 - 8 = 3x - 8
we can't subtract 3x-8
Doesn't add up; they need to have one solution or more for it to work.
Answer: Exact Form: x
=
−
45
/2
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
-9,-5, -1, 10 is the right order
=3*2+bx-6
= 6+bx -6
= 6-6+bx
=0+ bx
B=x
