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.
Thus, the rate of function is: 5/2
10 20
20 10
Answer:
The Inverse variation says that:
,
then the equation is of the form:
or
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:
....[1]
From the given table:
take any points
r = 20 and w = 10 then;
Substitute in [1] we have;
Simplify:
k = 200
The equation becomes:
We have to find the number of roses when there are 5 weeds.
⇒w = 5
then;
Divide both sides by 5 we get;
r = 40
Therefore, the number of roses are 40 when there are 5 weeds.
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?
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
