Decide whether each table could represent a proportional relationship. In the essay box explain if the relationship could be proportional, what would be the constant of proportionality?
Annie’s Attic is giving away $5 off coupons.
Answer:
This table does represent a proportional relationship because the sale price and original price are going up at the constant rate of 10
Step-by-step explanation:
The equation of line is y = -x + 25 and the constant of proportionality is 5
What exactly is a line equation?A line's equation is written as y = mx + b, where m is the slope and b is the y-intercept.
Furthermore, y - y1 = m (x - x1).
y = second point's y-coordinate
y1 = point one's y-coordinate m = slope x = point two's x-coordinate
x1 = point one's x-coordinate
The slope is m = (y2 - y1) / (x2 - x1).
Given the data,
Let the line equation be written as A.
The value of A is now
Let P be the initial point ( 15 , 10 )
Let's call the second point Q. ( 25 , 20 )
The slope of the line is now m = (y2 - y1) / (x2 - x1).
m slope = [tex]\frac{(20-10)}{(25-15)}[/tex]
m slope = [tex]\frac{-10}{10}[/tex]
m slope = -1
The equation for the line is now y - y1 = m (x - x1).
y - 10 = -1 ( x - 15 )
Simplifying the equation yields y - 10 = -x + 15.
We get y = -x + 25 by adding 10 to both sides of the equation.
So, if the selling price x is $10, the original price y is $ 15.
Hence , the equation of line is y = -x + 25 and the constant of proportionality is 5

Answer:
I believe it would be the second one i'm not exactly sure.
Step-by-step explanation:
If x-y=6 and x^2+y^2=24, find x^3-y^3.
Answer:
162.06
Step-by-step explanation:
sorry i'm not the best an explaining but i'm confident in my answer.
the first thing to do is get rid of the ² in x²+y²=24, we do this by √24 which ≅4.90 (i rounded to the hundreth place)
then we have this
x-y=6
x+y=4.90
I am using the elmination method. To do that you need to get two letters to have the same coefficient (in 4x 4 is the coefficient) with oposite signs (one possitive one negitive)
In our equation here we see that the same coefficient is 0, and there is oposite signs for y. Therefore we can add the two equations and get
2x=10.9 (the y cancels out)
now we have a simple equation and all that is left is to solve it
10.9/2=5.45
x=5.45
Now we need to find y we do that by pluging the x value into one of the equations I choose the first one becasue its easiest.
(5.45)-y=6
y= - .55
now that we have both x and y plug them into the final equation (5.45)³-(-.55)³= 161.89-(-.17) =162.06
Therefore x³-y³≅162.06!

the quotient of a number x and 3 is at most 4
an inequality is ?
the solution is ?
Answer: The inequality is x/3 [tex]\leq[/tex] 4 and x [tex]\leq[/tex] 12
Step-by-step explanation:
The quotient of x and 3 is the same as x/3 and the at most sign is less than or equal to. x/3 has to be less than or equal to 4 which can be represented by the inequality,
x /3 ≤ 4 Solve for x by multiplying both sides by 3.
x ≤ 12
a number x divided by 8 is less than -2
Answer: x/ 8 < -2 and x< -16
Step-by-step explanation:
A numer x is divided by 8 is the same as x/ 8 and x/8 has to be the less than -2 so it will be x/8 < -2
x/8 < -2 TO solve the inequality, multiply 8 on both sides to get
x < -16
The solution of expression is,
⇒ x < - 16
We have to given that,
An algebraic expression is,
''a number x divided by 8 is less than -2''
We can write as,
⇒ x / 8 < - 2
Solve for x,
⇒ x/8 < - 2
Multiply by 8;
⇒ x < - 2×8
⇒ x < - 16
Therefore, The solution of expression is,
⇒ x < - 16

To transmit information on the internet, large files are broken into packets of smaller sizes. Each packet has 1,500 bytes of information. An equation relating packets to bytes of information is given by b=1,500p where p represents the number of packets and b represents the number of bytes of information.
1. How many packets would be needed to transmit 30,000 bytes of information?
2. How much information could be transmitted in 30,000 packets?
3. Each byte contains 8 bits of information. Write an equation to represent the relationship between the number of packets and the number of bits.
Answer:
45,000,000 information could be transmitted in 30,000 packets
Explaination:
b=1500p
p= 30,000
so,
b= 1500 x 30000 = 45,000,000
Answer:
1- 20 packets for this one you have to divide 30,000 by 1,500
2- 45,000,000 bytes for this one you have to multiply 1,500 by 30,000
3- so if each byte is 8 bits of information and 1,500 bytes equal one packet than each packet equals 187.5 bits of information and if you have 30,000 packets than there will be 3,750 bits of information the equation is the number of bytes in a packet divided by the number of bits of information in a byte which is 1,500/8 = 187.5 and the amount of packets you have you divide it by 8 because it is the number of packets divided by the number of bits of information
