Evaluate the expression. 50 points!!

C

Step-by-step explanation:

If you notice, this is what the tangent-difference identity resembles. The tangent-difference identity is:

We have the expression:

So, our α is π/7 and our β is π/8. Therefore:

Simplify:

Subtract:

So, our answer is C.

And we're done!

answer: you need the equation in the question so i can answer it

step-by-step explanation:

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
