Answer:
See explanation
Step-by-step explanation:
We want to show that:

One way is to use the basic double angle formula:


We simplify further to get:

We simplify again to get;

This finally gives:

The square root and the squared cancel each other out so it would just be 27 to the first power,which is 27
Direct variation is y=kx, inverse variation is y=k/x....
-5y=-2x divide both sides by -5
y=2.5x
So this is a direct variation with a constant of 2.5
The solution is when the two functions meet x=2. The green function is f(x), and the red is g(x).
Answer:
(5,2)
Step-by-step explanation:
i am unsure of what your question is but if you want the point of intersection of the two lines its (5,2)
