The condition for an expression to be an <u>identity </u>is that both sides of equality must give the same value.
In this case, the equation that fulfills that condition is the first equation (1).
<u>Let’s prove it:</u>
1)
Applying distributive property:
Joining together similar terms on both sides of the equality:
<h2>
>>>>>>>This is true and fulfills the condition of identity</h2>
The other equations do not fulfill the condition:
2)
>>>>>>>This is not logic
3)
>>>>>>>This is not logic
4)
>>>>>>>This is not logic
Answer:B
y=13cos(1/13x)+13
Step-by-step explanation:
3t=7+5=12
3t=12
t=4
6t=6×4=24
The answer is 24
A. Y=1/2x + 2
