ivanzaharov [21]

<u>ANSWER:</u>

Kari bought 3 boxes of cookies to share. The algebraic expression is \frac{36}{x}

<u>Solution:</u>

Given, Kari bought 3 boxes of cookies to share with a book club.  

Each box contains 12 cookies.  

So, in total we have 3 x 12 cookies = 36 cookies.

Now, we have to find how many cookies can each person p will get.

Let, the total number of persons be x.

Then, after equally sharing the cookies,

\text { Number of cookies with each person }=\frac{\text {number } of \text { cookies available.}}{\text {total number of persons}}

=\frac{36}{x} \text { cookies. }

Hence, the algebraic expression is \frac{36}{x}

Given the function defined in the table below, find the average rate of change, insimplest form, of the function over the interv
Reil [10]

To find the average rate of change in a interval

a\leq x\leq b

We use the following formula:

\frac{f(b)-f(a)}{b-a}

Applying this to our interval

6\leq x\leq15

We have the following rate of change:

\frac{f(15)-f(6)}{15-6}=\frac{107-53}{9}=\frac{54}{9}=6

We have an average rate of change equals to 6.

What is the slope of a line perpendicular to the line that passes through (4, -3) and
m_a_m_a [10]

Answer:

1/2

Step-by-step explanation:

The slope of the points (4,-3) and (3,-1) is -2

The slope of a line perpendicular to said points would be the opposite reciprocal which would be 1/2

heres how you'd find the initial slope of the points

(4, -3)

-1  +2

(3, -1)

Slope= rise/run= 2/-1= -2
