what is the rate of change of the function enter - 1

Answer 1
Answer:

Answer:

The rate of function is: 5/2                            

Step-by-step explanation:

As we know that the rate of change of a function is a ratio that compares the difference between the output values to the difference between the corresponding input values

rate of change = change in y-values / change in y-values

So, all we need is to find the slope between any two points as the slope is basically termed as the rate of change.

\mathrm{Slope}=(y_2-y_1)/(x_2-x_1)

\left(x_1,\:y_1\right)=\left(-5,\:18\right),\:\left(x_2,\:y_2\right)=\left(-3,\:23\right)

m=(23-18)/(-3-\left(-5\right))

m=(5)/(2)

Thus, the rate of function is: 5/2

The number of roses (r) in a garden increases when the number of weeds (w) decreases. Write the correct equation for this scenario, and solve for the number of roses when there are 5 weeds.Weeds Roses
10 20
20 10

Answers

Number of roses (r) in a garden increases when the number of weeds (w) decreases, this supports an inverse relationship between the two variables. 
The formula is then therefore, r = k/w
Solve for constant first.
r = k/w
20 = k/10
200 = k

r=200/5
r=40 roses
40 roses when there are 5 weeds.

Answer:

The Inverse variation says that:

y \propto (1)/(x),

then the equation is of the form:

y = (k)/(x) or xy = k

Here, r represents the number of roses and w represents the number of weeds.

As per the statement:

The number of roses (r) in a garden increases when the number of weeds (w) decreases.

by definition of inverse variation:

rw = k          ....[1]

From the given table:

take any points

r = 20 and w = 10 then;

Substitute in [1] we have;

(20)(10)= k  

Simplify:

k = 200

The equation becomes: rw = 200  

We have to find the number of roses when there are 5 weeds.

⇒w = 5

then;

r(5) = 200  

Divide both sides by 5 we get;

r = 40

Therefore, the number of roses are 40 when there are 5 weeds.

A bookstore manager marks down the price if older hardcover books, which originally sell for b dollars, by 46%a. Write the mark down as a decimal
b. Write two expressions for the sale price of the hardcover book
c. What is the price of a hardcover book for which the original retail price was $29.00
d. If you buy the book in part c how much do you save by paying the sale price?

Answers

Answer:

a) 46% reduction = 1-(46/100)= 0.54

b) 46% reduction = 1-(46/100)= 0.54

price after reduction: b*0.54 =0.54b

or b-(b*46)/100 = b-(46b/100)= (100b-46b)/100 = 54b/100

c) 29*0.54=$15.66

gold 29-(54*29)/100 = $15.66

d) $29-$15.66=$13.34
