f(x) = 6x

To find the inverse, replace f(x) with Y:

y = 6x

Now switch the variables:

x = 6y

Solve for Y by dividing both sides by 6:

y = x/6

Now replace y with f^-1 (x):

f^-1 (x) = x/6

Answer:

58°

Step-by-step explanation:

Start with the equation 2x + 2 + 90 = 148

( I got the 90 from Angle B since it is a right angle.)

Combine like terms 2x + 92 = 148

( 90 and 2 didn't have variables so you could add them together.)

Subtract 92 from both sides 2x + 92 = 148

-92 -92

(The opposite of addition is subtraction.)

Now write out the new equation 2x = 56

Divide both sides by 2 $\frac{2x}{2}$ = $\frac{56}{2}$

You'll end up with... x = 28

To find the measure of angle BAC, plug in 28 where the x value is 2(28) + 2

This gives you the answer 58°

Given: tangent to Circle O. If m C = 57°, then m BDR =

Romashka-Z-Leto [24]

∠BCD = 57°
∴ ∠BDR = ∠BCD = 57° (angle that meets the chord and the tangent is equi-angular to the angle at the alternate segment)
