If f(x) = 6x + 3, find −1 ().

lianna [129]

Answer:

$f^{-1}(x)=(1/6)x-(1/2)$

Step-by-step explanation:

we have

$f(x)=6x+3$

Find the inverse function $f^{-1}(x)$

step 1

Let

y=f(x)

$y=6x+3$

step 2

Exchanges variables, x for y and y for x

$x=6y+3$

step 3

isolate the variable y

$x=6y+3$

$6y=x-3$

$y=(1/6)x-(1/2)$

step 4

Let

$f^{-1}(x)=y$

$f^{-1}(x)=(1/6)x-(1/2)$

A baker is selling a ton of pies. She puts them in crates and boxes. There are 65 crates and 121 boxy. Each crate contains 43 ap

marta [7]

Let's first find the number of apple pies.

apple pies = 65 crates x 43 apple pies per crate = 2795 apples pies

If each apple pie cost $12 then...

money from apple pies = 2795 apple pies x $12 = $33540

total pies sold = 2795 apple pie + 121 boxes x 76 sweet potato pies = 11991 pies

Zara has forgotten her 4-digit PIN code. She knows the first digit is a prime number and the 4 digits make a number divisible by

vredina [299]

Answer:

2,500 different sets

Step-by-step explanation:

According to the scenario, calculation of the given data are as follows,

Let 4-digit PIN code be WXYZ

As first digit is a prime number

So, W = 1, 2, 3, 5, 7

n(W) = 5

X and Y are number from 0 - 9

So, n(X) = 10 & n(Y) = 10

Z makes the whole number divisible by 2.

So, Z must even number

So, Z = 0,2,4,6,8 or n(Z) = 5

We can calculate the number of different sets by using following formula,

n(W) × n(X) × n(Y) × n(Z)

By putting the value, we get

5 × 10 × 10 × 5 = 2,500

4. When finding the intersection of two lines from both Algebra I and Geometry, you first "set the linear

Masteriza [31]

Answer:

The intersection point is (-4,-19)

Explanation:

The two given equations are:

y = 5x + 1

y = 2x - 11

To find the intersection point, we will start by equating the two given equations and solving for x

This is done as follows:

5x + 1 = 2x - 11

5x - 2x = -11 - 1

3x = - 12

x = -4

Then, we will use the x and substitute in any of the equations to get the value of y

Using the first equation:

y = 5x + 1 = 5(-4) + 1 = -19

Check using the second equation:

y = 2x - 11 = 2(-4) - 11 = -19 ................? checked

Therefore:

The intersection point between the two given equations is (-4,-19)

Hope this helps :)
