Which function is the inverse of f Superscript negative 1 Baseline (x) = negative one-fifth x minus four-fifths?
DedPeter [7]

Answer:

f(x) = -5x - 4

Step-by-step explanation:

We want to get the inverse of the following function:

f^-1(x) = (-1/5)x - 4/5

To do that, we have to replace x with f(x) and f^-1(x) with x, as follows:

x = (-1/5)f(x) - 4/5

And then solve for f(x), the inverse of f^-1(x).

x + 4/5 = (-1/5)f(x)

f(x) = -5x + (-5)4/5

f(x) = -5x - 4

To check our result we compute a pair (x, f(x))

x   f(x)

1   -5*1 - 4 = -9

which has to be equivalent to (-9, 1) in the original function

x      f^-1(x)

-9     (-1/5)*(-9) - 4/5 = 1

a plane averaged 400 mph on a trip going east, but only 280 mph on the return trip. The total flying time in both directions was
Liula [17]

Answer:

1400 miles

Step-by-step explanation:

Speed is the time rate of change of distance. It is the ratio of distance to time and is given by the equation:

Speed(S) = \frac{distance(d)}{time(t)}\\ S=\frac{d}{t}

plane averaged 400 mph on a trip going east, but only 280 mph on the return trip.

The time spent (t₁) in going east is given by:

S=\frac{d}{t_1}\\ t_1=\frac{d}{S} =\frac{d}{400mph}

The time spent (t₂) in going east is given by:

S=\frac{d}{t_2}\\ t_2=\frac{d}{S} =\frac{d}{280mph}

The total time (t) = t₁ + t₂

t = t₁ + t₂ = 8.5 hours

\frac{d}{400}+\frac{d}{280}  =8.5\\280d+400d=952000\\680d=952000\\d=1400miles\\

Therefore the one way distance is 1400 miles

Nina had 9 apples to share with 5 of her friends. If all 6 people get equal share , how many apples will each person get? How do
Umnica [9.8K]
<span> Nina + her 5 friends = 6 people
Then she has 9 apple to share with her and her friends.
Let’s calculate how many apple will each people get when they equally divide it with each other:
=> 9 – 6 = 3
Thus already have 1 apple each, now, let’s divide the remaining 3 apples
=> 3 / 6 = .5
So they have half of apple each. Let’s add
=> 1 + .5 = 1.5
Each person will get 1.5 apple.
=> 1.5 * 6 = 9</span>
