Find the inverse f(x)=8-9x
Sati [7]

Answer:

{f}^{ - 1} (x) =  -  \frac{1}{9} x  +  \frac{8}{9}

Step-by-step explanation:

f(x) = 8 - 9x

y = 8 - 9x

x = 8 - 9y

8 - 9y = x

- 9y = x - 8

y =  -  \frac{1}{9} x +  \frac{8}{9}

\boxed{\green{{f}^{ - 1} (x) =  -  \frac{1}{9} x  +  \frac{8}{9}}}

Choose the correct solution and graph for the inequality-5y<_-15
swat32

For this case we have the following inequality:

-5y \leq-15

To solve, we follow the steps below:

We divide between 5 on both sides of the inequality:

-y \leq \frac {-15} {5}\\-y \leq-3

We multiply by -1 on both sides taking into account that the sense of inequality changes:

y \geq3

Thus, the solution is given by all values of "y" greater than or equal to 3.

Answer:

y \geq3

See attached image

The vertical axis represents the "y" axis

The combined land area of the countries A and B is 159159​,973 square kilometers. Country A is larger by 473473 square kilometer
lora16 [44]

Answer:

The land area of country A and country B are 80223 sq.km. and 79750 sq.km. respectively

Step-by-step explanation:

Let the area of Country B be x

We are given that Country A is larger by 473 square kilometers.

Area of Country A = x+473

Total area of both countries = x+x+473

Total area of both countries = 2x+473

We are given that The combined land area of the countries A and B is 159​,973 square kilometers.

So, 2x+473=159​973

2x=159973-473

x=\frac{159973-473}{2}

x=79750

Area of Country A = x+473=79750+473=80223 sq.km.

Hence the land area of country A and country B are 80223 sq.km. and 79750 sq.km. respectively

What is the volume of a cube, if the length of one side is 12 cm?
irinina [24]
