If f(x) =tan(2x) then f'(pi/6)?
LiRa [457]
F ( x ) = tan ( 2 x );
f ` ( x ) = (1 / cos² x )· ( 2 x )` = 2 / cos² x
f` ( π/6 ) = 2 / cos² (π/6) = 2 / (√3/2)² = 2 : 3/4 =  8/3

Find the x-intercept and the y-intercept. then graph the equation. 11x+6y=-22
ra1l [238]

Answer:

x = \frac{-6}{11}y - 2

y = \frac{-11}{6}x + \frac{-11}{3}

Step-by-step explanation:

Let's solve for x.


y = \frac{-11}{6}x + \frac{-11}{3}


Step 1: Add -6y to both sides.

11x+6y+−6y=−22+−6y

11x=−6y−22

Step 2: Divide both sides by 11.

\frac{11x}{11} = \frac{-6y - 22}{11}

x = \frac{-6}{11}y - 2


Let's solve for y.

11x+6y=−22

Step 1: Add -11x to both sides.

11x+6y+−11x=−22+−11x

6y=−11x−22

Step 2: Divide both sides by 6.

\frac{6y}{6} = \frac{-11x - 22}{6} \\

y = \frac{-11}{6}x + \frac{-11}{3}
