1. x= Jacksons Cups y= Lucius Cups2. x - y= 5 6x + 3y = 300Substitution: 6 (y+5) + 3y = 300 6y + 30 + 3y = 300 9y = 270 dived both by 9 y=30 Sub y for other equation x - 30 = 5 add 30 to both sides x = 35 Answer: (35, 30) Graphing: x- y = 56x+ 3y = 300solve both for y y = x-5 6x + 3y = 300minus 6x from both sides the points are in y = mx + b y= 1x -5 y= -2x + 100 I will also leave the ss of the graph in the comments if you cannot see it My labels for the x-axis is Jacksons cups and y Is luscious cups. Elimination:x - y = 5 6x + 3y = 300 First I manipulated the equations by the following - 6 (x - y = 5 ) 1(6x + 3y = 300 ) -6x + 6y = -30 6x + 3y = 300 The 6 x's cancel and add the y's and real numbers together 9y = 270 dived both by 9 y= 30 Sub y for other equation x - 30 = 6 add 30 to both sides x= 30 The points are (35, 30) The solution is (35,30)They represent how many cups they sold. 35 is Jackson cups and 30 is Lucious's cups

if 9 calculators cost £96.30. How much do 13 calculators cost
Step-by-step explanation:
First, you want to start by creating an equation to find the unit rate
calculators = c
9c = 96.30
Solve!!!
9c/9 = 96.3/9
c= 10.7
A calculator costs $10.70 (Sorry I will be using the dollar sign instead)
Now you want to set an expression for 13 calculators
13c
Substitute 10.7 in
13(10.7)
Multiply them
$139.10
13 calculators cost $139.10
I hope this helps!!!

7,707 ÷ 24 with remainder
Answer:
321 remainder 3
Step-by-step explanation:
The remainder of 7,707 ÷ 24 is 3
What is the quotient remainder theorem?When we want to prove some properties of modular arithmetic we often make use of the quotient remainder theorem. It is a simple idea that comes directly from the long division. Given any integer A and a positive integer B, there exist unique integers Q and R such that
A= B * Q + R where 0 ≤ R < B
Given here 7,707 ÷ 24 this can be written as follows:
7707 = 321×24 + 3
Thus comparing with the above equation we get the remainder as 3
Hence the required form is 7707 = 321×24 + 3

All of the middle-school mathletes solve math problems at the same pace. Working together, six mathletes complete all of the summer homework in 22 hours. How many hours will the homework take if the number of mathletes? PLEASE HELP
Answer:
44 hours
Step-by-step explanation:
because if its half it will take twice as long
Answer:
44 hours
Step-by-step explanation:
If you decrease the amount of participants in half, the amount of time that it takes per work load automatically doubles. So if the original amount of hours that it took with six participants is 22. If we cut six into half, then 22 hours would double into 44. Then it would become 44 hours with three people. Also, for check, I did have this problem for RSM.

If c= 16, solve for b. (Timed!!!)
Answer:
b is 8√3 ⇒ A
Step-by-step explanation:
In the given triangle
∵ The Δ is the special right triangle 30°: 60°: 90°
∴ There is a ratio between its sides
∵ a is opposite to the angle of measure 30°
∵ b is opposite to the angle of measure 60°
∵ c is opposite the angle of measure 90°
∴ a: b: c = 1: √3: 2
∵ c = 16
→ By using the ratio between its sides
→ 30°: 60°: 90°
→ 1 : √3: 2
→ a : b : 16
→ By using cross multiplication
∵ b × 2 = √3 × 16
∴ 2b = 16√3
→ Divide both sides by 2
∴ b = 8√3

1. Melissa took out a loan of $50,000 with an interest rate of 2.3% for the start-up of the Math Cafe. How much will she owe the bank if the loan term is for five years? Explain how you got your answer.
Answer:
$55,750 a
Step-by-step explanation:
Given Principal P = $50,000
Rate R = 2.3%
Time T = 5 years
Get the interest first
Simple interest = PRT/100
Simple interest = 50,000*2.3*5/100
Simple interest = 500*2.3*5
Simple interest = $5,750
Amount = Principal + Interest
Amount = $50,000 + $5,750
Amount = $55,750
Hence she will owe the bank $55,750 after 5 years

g(x) is the transformation the parent function f(x)=x2 after being reflected over the x-axis and translated 4 units left. What is the equation for g(x)?
Answer:
Reflection across the x-axis: y = − f ( x ) y = -f(x) y=−f(x) The concept behind the reflections about the x-axis is basically the same as the reflections about the y-axis. The only difference is that, rather than the y-axis, the points are reflected from above the x-axis to below the x-axis, and vice versa.
the equation for g(x) after reflected over x axis and translated 4 units left
[tex]g(x)=-(x+4)^2[/tex]
Given :
Parent function is [tex]f(x)=x^2[/tex]
When a graph is reflected over x-axis then f(x)=-f(x)
When a graph is translated 'a' units left then we add 'a' with
f(x) becomes f(x+a)
Parent function f(x) is reflected over x-axis , multiply -1 with f(x)
so , [tex]f(x)=-x^2[/tex]
Now we translate 4 units to the left, add 4 with x
[tex]g(x)=-x^2\\g(x)=-(x+4)^2[/tex]
The final equation of g(x) is
[tex]g(x)=-(x+4)^2[/tex]

the product of digits in a two digit number is 12. the number formed by interchanging the digits of that number will be 9 less than the original number. find the original number.
Answer:
Let the tens digit of the required number be x and the units digit be y. Then,
x+y=12 .........(1)
Required Number = (10x+y).
Number obtained on reversing the digits = (10y+x).
Therefore,
(10y+x)−(10x+y)=18
9y−9x=18
y−x=2 ..........(2)
On adding (1) and (2), we get,
2y=14⟹y=7
Therefore,
x=5
Hence, the required number is 57.
Step-by-step explanation:
Hope it is helpful...
Step-by-step explanation:
Let X be the 1st digit and Y be the 2nd digit of the two digit number.
We have X * Y = 12 and (10X + Y) = (10Y + X) + 9.
=> XY = 12 and 9X = 9Y + 9
=> XY = 12 and X = Y + 1
Therefore X = 4 and Y = 3. => Number is 43.

Which graph has a rate of change of zero?
Answer:
The horizontal line
Step-by-step explanation:
Answer:
The horizontal line has a rate of change of 0, since it has a slope of 0Step-by-step explanation:
On the other hand, the vertical line has an undefined slope.
Slope is rise/run or change n y over change in x.
If the y axis coordinate never changes, then rise = 0. The only number that changes is x. x changes 1 for every 0 y changes. 0/1 = 0.
In a vertical line, however, the x coordinate is the one that doesn't change. We reverse the number from before, but we have a problem 1/0 is an undefined number since you cannot divide by 0.

and comment me to tell your country
I need help with this please
Answer:
omg whats the answer
Step-by-step explanation:
Someone please help me on these 2 problems!
1) function 2) not a function
the first one is a function because its y values are the same number (3), which means it is a horizontal line and horizontal lines are functions.
the second one is not a function because the coordinates cannot have different inputs but different outputs. each input must have only one output.
the coordinates for the second one are:
(2,5); (1,1); (1,2); (3,2)
and a function cannot have two same x-coordinates. it must pass the vertical line test which is a way to tell if something is a function or not. since the second graph does not pass the vertical line test, it is not a function
hope this helps :)
