Answer:
tan²x
Step-by-step explanation:
Using the Pythagorean identity
sin²x + cos²x = 1
Divide all terms by cos²x
+
=
, that is
tan²x + 1 = sec²x ( subtract 1 from both sides )
tan²x = sec²x - 1
The right answer is Option C: x< -5 or x>2
Step-by-step explanation:
Given inequalities are;
2x – 2 < –12 or 2x + 3 > 7
We will solve first inequality;
2x – 2 < –12
Adding 2 on both sides;
Dividing both sides by 2
Solving the second inequality
2x + 3 > 7
Subtracting 3 from both sides
Dividing both sides by 2
Therefore;
x< -5 or x>2
The right answer is Option C: x< -5 or x>2
