Answer: No, because an identity is an equation that is always true and cos(theta) - sin(theta) does not always equal 1.
Hope this helped! :)
In Step 6, the equation is ...
-12 = x - 36
In step 7, the equation is ...
-12 +36 = x -36 +36
Clearly, to get to step 7, 36 has been added to both sides of the equation.
Adding 36 to both sides of the equation is justified by ...
... C) Addition Property of Equality

<em>More about the addition property of equality</em>
The addition property of equality says you can add the same value to both sides of an equation without changing the values of the variables that make the equation true. Here, x=24 makes the equation of step 6 true, and x=24 makes the equation of step 7 true.
Answer:
b=3 b=0
Step-by-step explanation:
-8|4b-6|+9=-39
Subtract 9 from each side
-8|4b-6|+9-9=-39-9
-8 | 4b-6| = -48
Divide by -8
-8/-8 | 4b-6| = -48/-8
| 4b-6| = 6
When solving the absolute value, there is a positive and a negative solutions
4b-6 = 6 and 4b-6 = -6
Add 6 to each side
4b-6+6 =6+6 4b-6+6 = -6+6
4b =12 4b = 0
Divide by 4
4b/4 =12/4 4b/4 = 0/4
b=3 b=0
