(-2,17)(-1,13)(1,5)(2,1)(3,-3)<br> The rate of change is ____.

7nadin3 [17]

Answer:

The rate of change in -4

Step-by-step explanation:

The rate of change is also known as the slope

To do this, take two points {(-2, 17) , (-1, 13)} and find the slope

m = slope

m = change in y/change in x

m = 13 - 17/-1 - (-2)

m = -4/1

m = -4

The rate of change in -4

Furkat [3]

Answer:

186

Step-by-step explanation:

The area is given by ...

(f • g)(3) = f(3) • g(3) = (3+3) • (12•3 -5) = (6)(31)

(f • g)(3) = 186

In the library at lenape elmentary school, there are 3/8 as, many fiction books as there are nonfiction books. There are 44 book

N76 [4]

Answer:

12 fiction books.

Step-by-step explanation:

Let b represent number of non-fiction books.

We have been given that in the library at Lenape elementary school, there are 3/8 as many fiction books as there are nonfiction books. So number of fiction books would be $\frac{3}{8}x$ .

We are also told that there are 44 books in school library. We can represent this information in an equation as:

$x+\frac{3}{8}x=44$

Let us solve for x.

$\frac{8x}{8}+\frac{3}{8}x=44$

$\frac{8x+3x}{8}=44$

$\frac{11x}{8}=44$

$\frac{11x}{8}\cdot \frac{8}{11}=44\cdot\frac{8}{11}$

$x=4\cdot 8$

$x=32$

Therefore, there are 32 non fiction books in the library.

Number of fiction books would be $\frac{3}{8}x\Rightarrow \frac{3}{8}*32=3*4=12$

Therefore, there are 12 fiction books in the library.

If function and inverse be

$\\ \rm\longmapsto f(x)\:and\:f^{-1}(x)$

Both will seem to be opposite and similar .

Look at the first one

It is showing like 1 is function and other one is its inverse(Attachment )

Hence 1st one is the answer
