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

Valentin [98]

Hello,

The inverse of the function is f^-1(X)=-3-x

How?

f (x)=-x-3

replace f(X) with y

y=-x-3

interchange the variables

x=-y-3

solve for y and replace f^-1 (X)

Hope this helps

What is the slope of the line through (1, -1)and (5,-7)<br> Choose 1 answer:

nalin [4]

Answer:

-3/2

Step-by-step explanation:

the formula for slope is y1-y2/x1-x2

where

y1 is the first point's y coordinate

x1 is the first point's x coordinate

y2 is the second point's y coordinate

x2 is the second point's y coordinate

so now we can plug our points in

-1-(-7)/1-5

6/-4

simplify

-3/2

Question 9

Wittaler [7]

Answer:

Part A) Barbaroid will be executed

Part B) 75 more globin soldiers

Step-by-step explanation:

The army sizes of ORC leaders are

normally distributed with a mean of 5600 goblin soldiers and a standard deviation of 750 goblin soldiers.

The rule is that, if an Orc Leader shows up with an army of a z-score lower than

-1.5, he is immediately executed.

We want to determine whether Lord Barbaroid, an Orc Leader, who appears with an army of 4400 goblin soldiers,

based on the Orc Rule, will he be executed or not.

We find the z-score corresponding to 4400 using

$z = \frac{x - \mu}{ \sigma}$

We substitute x=4400 , the standard deviation and the mean to get:

$z = \frac{4400 - 5600}{750} = - 1.6$

Since Lord Barbaroid's z-score , -1.6 is less than -1.5 he will be executed.

Part B)

We want to find how many more goblin soldiers Lord Barbaroid have needed in order to NOT be executed and meet that Z-Score.

So we need to find the number of globin soldiers that corresponds to -1.5.

$- 1.5 = \frac{x - 5600}{750}$

$750 \times - 1.5 = x - 5600$

$- 1125 = x - 5600 \\ x = 5600 - 1125$

$x = 4475$

Therefore Barbaroid needed 4475-4400=75 more globin soldiers.
