How to solve f(x)=2x+1 when x=a-b?

f(2) = 3/2

Step-by-step explanation:

Let u = 2x-1.

Then x = (u+1)/2.

Substituting into f(2x-1) = x, we get f(u) = (u+1)/2.

Thus, f(2) = (2+1)/2 = 3/2.

Do a u-substitution!

Let u = 2x-1.

Then x = (u+1)/2.

Substituting into f(2x-1) = x, we get f(u) = (u+1)/2.

Thus, f(2) = (2+1)/2 = 3/2.

yes

yes yes yes

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
