What is the inverse of the function f(x)=-x?

1 answer:

6 0

To find the inverse we have to first change the function notation to 'y'

So

f(x) = -x becomes y = -x

Next, we have to switch the x and y values

So, y = -x becomes x = -y

Now, we have to solve for y.

y = -x

So the inverse of f(x) = -x is:

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

Tatiana wants to give friendship bracelets to her 32 classmates. She already has 5 bracelets, and she can buy

Aloiza [94]

4p+5=32 or 7 packages

I got this because there are 4 bracelets in one package and she doesn't know how many packages she needs so we put p for packages next to the 4 and you already have 5 so you add the 5 to it, all of that should come out to 32. If the equation wasn't what you were looking for you subtract 5 from 32 and get 27, then you divide 4 by 27 and you get 6.75, then you round it up and you get 7. The number of packages she needs is 7.

Answer:

Step-by-step explanation:

we know that the triangle to the center is an isosceles, so the two angle on the circle of that triangle are the same. both 41, so 41*2 =82

all the way around that isosceles triangle is 180 so

180-82 = 98

the angle at O is 98°

the arc BC spans 98°

angle 'a' is 1/2(98°)
