Answer:
40%
Step-by-step explanation:
Every week you he buys 4 number of 2 Litres bottle of lemonade.
Thus, let's say cost of each bottle is X.
This means he total cost is 4X
Now, total litres = 4 × 2 = 8 litres
Thus, cost per litre = 4X/8 = ½X
Now, we are told that Last week the bottles on the shelf were limited edition “2.5 litres for the price of 2 litres” bottles ".
This means that now, it is cheaper.
However, the supermarket also had a “buy 3 bottles, get another one free” offer.
Now since he buys 8 litres weekly, now since it's 2.5 L bottle, he will buy 3 since he will be given 1 free for every 3 he buys.
Thus, total litres he is paying for = 2.5 × 3 = 7.5 litres
Thus, cost per bottle is; 3X
Since he is getting 1 bottle free, then total bottle he gets is; 7.5 L + 2.5 L = 10L
Thus;
cost per litre is now; 3X/10
Difference in costs per litre is;
½X - 3X/10 = X/5
percentage of the cost of four bottles of lemonade lower than usual last week = (X/5)/(½X) × 100% = 2/5 × 100% = 40%

How would you find the quadratic that goes through the point (4,0), the axis of symmetry is x=7, and it also goes through the point (1,5)?
9514 1404 393
Answer:
y = (5/27)(x -7)^2 -5/3
Step-by-step explanation:
Use the given points to find the unknowns in the equation.
If the axis of symmetry is x=7, then the equation can be written in the form ...
y = a(x -7)^2 +b
Filling in the two point values, we have two equations:
0 = a(4 -7)^2 +b ⇒ 9a +b = 0
5 = a(1 -7)^2 +b ⇒ 36a +b = 5
__
Subtracting the first equation from the second, we have ...
(36a +b) -(9a +b) = (5) -(0)
27a = 5
a = 5/27
Substituting that value into the first equation gives ...
9(5/27) +b = 0
5/3 +b = 0
b = -5/3
So, the quadratic can be written in vertex form as ...
y = (5/27)(x -7)^2 -5/3

The variables are x and y, the coefficients are -2 and 3/4, and the constant is 3/7 in the given algebraic expression 3x/4 − 2y + 3/7.
What is the algebraic expression?Algebraic expressions are mathematical statements that comprise at least two variables or integers.
What are arithmetic operations?Arithmetic operations can also be described via subtracting, dividing, and multiplying built-in functions.
We have been the given algebraic expression as :
⇒ 3x/4 − 2y + 3/7
Here variables are x and y
The coefficients are -2 and 3/4
The constant is 3/7
Therefore, the variables are x and y, the coefficients are -2 and 3/4, and the constant is 3/7 in the given algebraic expression 3x/4 − 2y + 3/7.

y = -4x - 12
What is the slope(m) and the y-intercept (b)
Answer:
x=6.0
Step-by-step explanation:
the slope (m) is -4, indicating a downward slope, and the y-intercept (b) is -12,
In the equation y = -4x - 12, the coefficient of x, -4, represents the slope of the line. The slope (m) is the ratio of the vertical change to the horizontal change between any two points on the line. In this case, the slope is -4, indicating that for every unit increase in x, the y-value decreases by 4.
The constant term, -12, represents the y-intercept (b). The y-intercept is the point where the line intersects the y-axis. In this equation, the y-intercept is -12, which means that the line crosses the y-axis at the point (0, -12).
To summarize, the slope (m) is -4, indicating a downward slope, and the y-intercept (b) is -12, representing the point where the line crosses the y-axis.

The double number line shows that 4 pounds of tomatoes cost $14. Draw tick marks and write labels to show the prices of 1, 2, and 3 pounds of tomatoes.
Answer:
every tick is 3.50
Step-by-step explanation:
14/4=3.5
The price of one, two, and three pounds of tomatoes is $10.5. Each quantity is represented by its own number line in a double number line, with corresponding pairs of values lined up.
How are double number lines created?Equal ratios are represented by two parallel number lines in a double number line diagram. The tick marks are in the same places on both number lines.Despite the fact that the other numbers change frequently, the tick marks labeled with 0 always line up.Diagrams with a double number line can show you how two quantities are related in terms of their ratios.They work best when the quantities have different units. (The unit rate is represented by the number 1) Students can more easily "see" that the same ratio can take many different comparable shapes when using double number line diagrams.Therefore,
Given,
4 pounds of tomatoes cost = $14
We find the prices of 1, 2, and 3 pounds of tomatoes
14/4 = 3.5
So,
1 lb = 3.5
2 lbs = 2× 3.5 = 7
3 lbs= 3 × 3.5 = 10.5
Hence, The price of one, two, and three pounds of tomatoes is $10.5.
