Answer:
y = 4(3)^x
Step-by-step explanation:
Here, we want to write the exponential equation
From the question, we have the equation tripling in x value every year and the original amount is 4
The exponential equation is of the form;
y = a(b)^n
In this case;
a = 4 , b = 3 and n = x
So we have the equation as;
y = 4(3)^x
If lucy has a card buiness she has an oder to make 65 cards she makes the same number of cards everyday for 7 days how many cards does she have to make on the last day
Answer:
2
Step-by-step explanation:
Total number of cards = 65
she makes the same number of cards everyday for 7 days
Number of days = 7
Cards per day = 65 / 7 = The result is 9 with a remainder of 2.
This means, she makes 9 cards per day for 7 days. Then on the last day she is left with 2 cards to make.

Book club A charges $20 for membership and $2 per book rental. Book club B charges $10 for membership and $3 per book rental. For how many movie rentals will the cost be the same at both book clubs? What does that cost?
Given:
Book club A charges $20 for membership and $2 per book rental.
Book club B charges $10 for membership and $3 per book rental.
To find:
The number of books for which the cost be the same at both book clubs.
Solution:
Let x be the number of books.
Book club A charges $20 for membership and $2 per book rental. So, the total cost is
[tex]C_1=20+2x[/tex] ...(i)
Book club B charges $10 for membership and $3 per book rental. So, the total cost is
[tex]C_2=10+3x[/tex] ...(ii)
Equating (i) and (ii), we get
[tex]10+3x=20+2x[/tex]
[tex]3x-2x=20-10[/tex]
[tex]x=10[/tex]
The total cost is
[tex]C_1=20+2(10)[/tex]
[tex]C_1=20+20[/tex]
[tex]C_1=40[/tex]
Therefore, the total cost at both book clubs are same for 10 rental books and that cost is $40.
Chau and Yoko each opened a savings account today. Chau opened his account with a starting amount of $460, and he is going to put in $60 per month. Yoko opened her account with a starting amount of $530, and she is going to put in $50 per month.
Let x be the number of months after today.
(a) For each account, write an expression for the amount of money in the account after x months.
Amount of money in Chau's account (In dollars) =
Amount of money in Yoko's account (in dollars) =
(b) Write an equation to show when the two accounts would have the same amount of money.
Answer:
A1-60x+460
A2-50x+530
B-60x7+460
50x7+530
Step-by-step explanation:
A1 and A2-since x is equivalent to number of months we multiply the number of months then add it to the original cost to get how much total you get in the account.
B-you add 50 to 530 and 60 to 460 until they equal the same amount in this case its 7 times.

All I can say is that the slope is 1/5
Answer:
Same thing as my last answer, but with a different graph.
Step-by-step explanation:
You know a point. X = 10 and y=40
by this definition you can without the hassle, know to divide both values by 10 to get the lowest numbers possible. y= 4x
using that, data of the slope, try and answer the question (follow my guides from last time ;) )

what must be multiplied to 3x + 7y to get 9x² - 49y²?
help.
Answer:
square the whole equation
Step-by-step explanation:
so, it will change from (3x + 7y)² to 9x² - 49y²
I hope this helps a little bit.
Answer:
(3x - 7y)
Step-by-step explanation:
we know that
.. (a + b) (a - b) = (a^2 - b^2)
=> (a + b) = (3x + 7y)
=>. (a^2 - b^2) = (9x^2 - 49y^2)
=> so, (a - b).= (3x - 7y)
hope it helps
X=
(-6x+125) (11x + 6)
9514 1404 393
Answer:
x = 7
Step-by-step explanation:
The base angles of an isosceles triangle are congruent, so ...
11x +6 = -6x +125
17x = 119 . . . . . . . . . add 6x-6 to both sides
x = 7 . . . . . . . . divide by 17

When a standard die is rolled, find the probability of getting a. 5 b. A number larger than 2 c. An odd number.
Answer:
P(getting a 5)=[tex]\frac{1}{6}[/tex]
P(number larger than 2)=[tex]\frac{2}{3}[/tex]
P(numbers which are odd) =[tex]\frac{1}{2}[/tex]
Step-by-step explanation:
When a standard die is rolled, we get sample space as {1,2,3,4,5,6}
So, let's use formula
P(E)=[tex]\frac{outcomes favorable to event E}{Total number of outcomes}[/tex]
For part A:
Event is getting a 5.
So, out of 6 samples , we get one 5 as outcome
So,
P(getting a 5)=[tex]\frac{1}{6}[/tex]
For part B:
The numbers larger than 2 are {3,4,5,6}
So, p(number larger than 2)=[tex]\frac{4}{6} =\frac{2}{3}[/tex]
P(number larger than 2)=[tex]\frac{2}{3}[/tex]
For part C:
The numbers which are odd are {1,3,5}
So, p(numbers which are odd)=[tex]\frac{3}{6 } =\frac{1}{2}[/tex]
P(numbers which are odd) =[tex]\frac{1}{2}[/tex]

A farmer is creating a rectangular garden such that the length is four times the width. The
area of the garden is 2077 square feet. Write and solve an equation to determine the width
of the garden, to the nearest tenth of a foot.
Answer:
Width of the garden = 22.8 foot
Step-by-step explanation:
Area of the rectangular garden = 2077 square feet.
Let
Width of the garden = x
Length of the garden = 4x
Area of a rectangular garden = length × width
2077 = 4x * x
2077 = 4x²
x² = 2077/4
x² = 519.25
find the square root of both sides
x = √519.25
x = 22.787057730211
To the nearest tenth of a foot.
x = 22.8 foot
Width of the garden = 22.8 foot

Sam is needing to make copies of a flyer for his new business. Store W charges $5 for unlimited copies and store Z charges $0.20 per copy and $2 for using the machine.
How many copies makes both stores cost the same amounts?
Answer:
I believe it would be 15 copies.
Step-by-step explanation:
Store W gives you unlimited copies for 5 dollars, so the number of copies doesn't matter for store W, they do not affect the cost. So, you will have to find how many copies from store Z will cost 5 dollars. Now, it tells you store Z charges 2 dollars for the use of the machine, so you can go ahead and subtract 2 from 5 (total amount to make it equal). That being done leaves you with 3 dollars for the copies themselves, it tells you each copy costs $.20. So, now all you have to do is divide 3 by 0.20, which gives you 15.
