Which function is the inverse of f(x) =2x +3

Answer:

 -1

f     (x) = x/2 - 3/2

Step-by-step explanation:

I choose to address this question by actually finding the inverse of f(x) = 2x + 3.

1) replace f(x) with y:  y = 2x + 3

2) interchange x and y:  x = 2y + 3

3) solve this result for y:  2y = x - 3 , or  y = (x - 3)/2.  This is the same as the second answer choice.  Label this result as

 -1

f     (x) = x/2 - 3/2

F(x)=
f(x) = 2x + 3
let y = 2x + 3
make y subject of the formula
x = \frac{y - 3}{2}
replace y with x above
f ^{ - 1 }  =  \frac{x - 3}{2}

A business spends $14,000 to produce a new board game. Each game costs $1.90 to produce and is sold for $9.99. How many games mu
barxatty [35]
Divide $14,000 by $9.99 = 1401 board games

Since we know $14,00 is how much has been spent on the board game in total, the price to make each board ($1.90) game isn't necessarily relevant.

So you take the profit made from each game and divide that from how much was spent for the board game.

Evaluate the limit of tan 4x/ 4tan3x​
Brut [27]

Answer:

  1/3

Step-by-step explanation:

The ratio is undefined at x=0, so we presume that's where we're interested in the limit. Both numerator and denominator are zero at x=0, so L'Hôpital's rule applies. According to that rule, we replace numerator and denominator with their respective derivatives.

  \displaystyle\lim\limits_{x\to 0}\dfrac{\tan{(4x)}}{4\tan{(3x)}}=\lim\limits_{x\to 0}\dfrac{\tan'{(4x)}}{4\tan'{(3x)}}=\lim\limits_{x\to 0}\dfrac{4\sec{(4x)^2}}{12\sec{(3x)^2}}=\dfrac{4}{12}\\\\\boxed{\lim\limits_{x\to 0}\dfrac{\tan{(4x)}}{4\tan{(3x)}}=\dfrac{1}{3}}

I'm not sure how to set this up
masya89 [10]
So hmmm notice the picture below

recall the "inscribed angle" theorem, an angle inscribed is half the intercepted arc

now, the line BA goes through the center, and to each end, thus is a diameter, the point of tangency, where a tangent hits the diameter or radius of a circle, is always a right-angle

If f(x) = 6x +5 and g(x) = 2x – 7 find (fºg)(x)
adell [148]

Answer:

f(g(x)) = 12x - 37

Step-by-step explanation:

Step 1: Define

f(x) = 6x + 5

g(x) = 2x - 7

Step 2: Find f(g(x))

f(g(x)) = 6(2x - 7) + 5

f(g(x)) = 12x - 42 + 5

f(g(x)) = 12x - 37

Complete the equation.<br> (-1)^39=?
GalinKa [24]

Answer:

  -1

Step-by-step explanation:

The total number of minus signs is odd, so the product is negative.

  (-1)^39 = -(1^39) = -1
