Step-by-step explanation:

Standard form: Ax + By = c, where a, b, and c are constants.

<u>Distribute</u>

y - 8 = -7x - 14

<u>Add 8 and 7x to both sides:</u>

If cosa=1/2(a+1/a), verify that. cos2a=1/2(a²+1/a²)​
Alborosie

Answer:

see explanation

Step-by-step explanation:

using the identity

cos2a = 2cos²a - 1 , then

cos2a

= 2[ \frac{1}{2}(a  + \frac{1}{a}) ]² - 1

= 2 [ \frac{1}{4} (a² + \frac{1}{a^2} + 2) ] - 1

= \frac{1}{2} (a² + \frac{1}{a^2} ) + 1 - 1

= \frac{1}{2} (a² + \frac{1}{a^2} ) ← thus verified
