Answer:
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form 
or 
Let
c ----> the total cost of the boat rental
d ---> is the number of days, the family rents the boat
we know that
Kaya's family spends $105 to rent a boat for 7 days
so
For d=7 days, c=$105
Find the value of the constant of proportionality k
substitute the given values
therefore
The linear direct equation is equal to
For this problem you can create a proportion.
Since 31,100 copies is 7.8% of the total copies spoke up to date you can make this proportion:
31,100. 7.8%
——— =. ———
x. 100%
Now you cross multiply and you will get
7.8x=3,110,000
After this you solve for x by isolating the variable.
7.8x/7.8. 3,110,000/7.8
x=398,717.949
Since the question asks you to round to the nearest whole number which is 7 then the final answer would be 398,718
Answer: There has been 398,718 copies sold to date.
Yes he is correct because when you multiply 3 and 2 y
Answer:
3d one
Step-by-step explanation:
Answer:
C. (–4, 0), (–2, 0), (1, 0), and (3, 0).
Step-by-step explanation:
The points where the graph intersects the x axis have y coordinates of zero and the given x coordinates.
(–4, 0), (–2, 0), (1, 0), and (3, 0) is the answer.
