Step-by-step explanation:

Given

f(x) = 2x - 5

f^-1(x) = ?

we know

Let

y = f(x)

Or y = 2x - 5

Now Interchanging the role of x and y we get

x = 2y - 5

or 2y = x + 5

therefore y = (x+5) / 2

Therefore, f^-1(x) = ( x + 5 ) / 2

Hope it will help :)❤

An american roulette wheel has 38 slots, of which 18 are red, 18 are black, and 2 are green (0 and 00). if you spin the wheel 38

Alexeev081 [22]

Intuitively, one would think the ball would land in the green spot 2 out of the 38 times, since there are 38 slots and 2 are green.

The probability that it lands in a green section is 2/38. Multiplying this by the number of times the experiment is performed, we get (2/38)(38) = 2.

A used-droid dealership buys a droid for $2900 and then sells it for $4300. What is the percent increase?

Anna71 [15]

The percent increase is 48.28

Step-by-step explanation:

Given,

Purchase price of used-droid = $2900

Selling price of used=droid = $4300

Profit = Selling price - purchase price

Profit = 4300-2900 = $1400

Percent increase = $\frac{Profit}{Purchase\ price}*100$

$Percent\ increase=\frac{1400}{2900}*100\\\\Percent\ increase=\frac{140000}{2900}\\\\Percent\ increase=48.275\%$

Rounding off to nearest hundredth;

Percent increase = 48.28%

The percent increase is 48.28

What are the range values of the function f (x ) = 3x + 4 for the domain values {-5, -1, 0, 2, 7}?

Airida [17]

Answer:

Range values are:

{-11, 1, 4, 10, 25}

Step-by-step explanation:

Domain values are the possible x values that can be entered into the function, or the inputs. Range values are the y values, or the outputs. By inserting every value in the set into the function, we get the outputs (y values)

-15 + 4 = -11

-3+4 = 1

0 + 4 = 4

6 + 4 = 10

21 + 4 = 25

Remember to put them in order.
