Answer:

see explanation

Step-by-step explanation:

Using the trigonometric identity

tanx = \frac{1}{cotx}

Consider the left side

\frac{cotA-1}{cotA+1} ← divide terms on numerator/denominator by cotA

= \frac{\frac{cotA}{cotA}-\frac{1}{cotA}  }{\frac{cotA}{cotA}+\frac{1}{cotA}  }

= \frac{1-tanA}{1+tanA}

= right side , thus proven

x+6=4x-21

If $60 is the original price and $9 is the amount discount what is 15% of the original price
pantera1 [17]

I'm kinda confused by this question, but, If $60 is the original price, and you want to know what 15% of the original price ($60) is.. It would be $9, the "amount discount".

If this isn't the answer you wanted please tell me and explain the question a bit more to me if you can and I will try my best to help.

Thank you.
