Incomplete question. The full question read;
My local store sometimes runs offers on some of its products. There are three different types of offers that could be in place:
Buy a certain number of a particular product and get an extra one for half price.A percentage discount (always a multiple of 5%) on one particular product.A percentage discount (always a multiple of 5%) on purchases worth a total of more than $10.The store only ever has one of these offers in place at any time.
Last week I bought
3 cartons of orange juice for $4 each1 loaf of bread for $35 packets of snacks for $1 eachThis week I bought the same set of items, but only paid $18 even though the individual items still had the same price.
(4) There are two possible offers that could be applied to orange juice that would each explain this reduction in the total bill.
What are these two offers?
(5) What are the other two offers that could explain the reduction in the total bill?
Answer:
1. Buy a certain number of a particular product and get an extra one for half price
Step-by-step explanation:
By buying 2 and getting one at half the price matches the offer:
Buy a certain number of a particular product and get an extra one for half price.This means two (2) cartons of orange juice cost $8 (4*2) + $2 cost the extra one at half price.
solve for X (3X+1) (10) (22) (7x-1)
Answer:
The value of x is 8
Step-by-step explanation:
In the given triangle
∵ A line segment joining points on two sides and parallel to the 3rd side
→ That means this line segment divided the two sides into equal ratios
∵ It divided the 1st side into 10 and 3x + 1
∵ It divided the 2nd side into 22 and 7x - 1
∴ [tex]\frac{10}{3x+1}[/tex] = [tex]\frac{22}{7x-1}[/tex]
→ By using cross multiplication
∵ 10(7x - 1) = 22(3x + 1)
∴ 10(7x) - 10(1) = 22(3x) + 22(1)
∴ 70x - 10 = 66x + 22
→ Subtract 66x from both sides
∵ 70x - 66x - 10 = 66x - 66x + 22
∴ 4x - 10 = 22
→ Add 10 to both sides
∴ 4x - 10 + 10 = 22 + 10
∴ 4x = 32
→ Divide both sides by 4
∴ x = 8
∴ The value of x is 8
Compare the function with the parent function. Without graphing, what are the vertex, axis of symmetry, and transformations of the given function?
y = 8x - 21 - 7
Answer:
The parent function is: y = x
First, here we have two types of transformations, and we could define them in a general way as:
if we start with a function f(x)
Vertical dilation/contraction: A vertical dilation/contraction of scale factor A (A is always positive) is written as:
g(x) = A*f(x)
Vertical translation:
We can write a vertical translation of A units upwards as:
g(x) = f(x) + A
And a vertical translations of A units down can be written as:
g(x) = f(x) - A.
In this case, the transformations are:
first, a dilation of scale factor 8.
Then a translation down of 21 units
then another translation down of 7 units.
y = 8*X - 21 - 7
y = 8*x - 28.
As this is a linear equation, there are no axis of symmetry, we only could have a line of symmetry along the same line y = 8*x - 28
Again, as this function is a linear equation there is no vertex.

Answer:
65 miles
Step-by-step explanation:
Answer:
65MPH (or 65 miles)
Step-by-step explanation:
I used a proportion:
487.5MI/7.5HR = ?MI/1HR
(mi/hr = mi/hr)
cross multiply:
487.5 x 1 = 487.5
then divide:
487.5 divided by 7.5 =
65 miles

You use substitution to solve a system of equations and, after simplifying, end with a statement that says 7 = 7. Describe what this statement means about the number of solutions and about the graph of the system. .
Answer:
System of equations are independent, if 2nd equation is not multiplication of firstequation by some number . ... Simplify the 2nd equation: ... y - 2x = -7 ... If you solve the equationsalgebraically and you get a solution such as 5=5, then ... If you use either method and end up with astatement that's always true i hope this helps
Step-by-step explanation:
Answer:
Sample Response: Since the statement is true, there are an infinite number of solutions to the system. This statement also indicates that the lines are equivalent.

Answer:
The student had a total of 25 questions on his test.
Step-by-step explanation:
Given that:
Number of questions answered correctly in the test = 20
Percentage scored in the test = 80%
Let,
x be the total number of questions on test.
We know that 80% of the test is 20 questions, therefore,
80% of x = 20
[tex]\frac{80}{100}x=20\\0.8x=20[/tex]
Dividing both sides by 0.8
[tex]\frac{0.8x}{0.8}=\frac{20}{0.8}\\x=25[/tex]
Hence,
The student had a total of 25 questions on his test.

A student bought 3 boxes of pencils and 2 boxes of pens for $6. He then bought 2 boxes of pencils and 4 boxes of pens for $8. Find the cost of each box of pencils and each box of pens.
Answer:
.
Step-by-step explanation:
Each box of pens are valued at $1.50, thus for 2 boxers it would be 1.50 x 2 = $3. Thus, 2 boxes of pens = $3. Each box of pencils cost $1. therefore 3 boxes of pencils valued at $1 each = to $3. Final equation $3 + $3 = $6 for the first purchase. Using the same numbers we valued the 2 boxes of pencils at $1 each = $1 pencil box + $1 pencil box = $2 for 2 boxes. Then 4 pen boxes valued at $1.50 each = to $1.50 x 4 = $6 Final equation $6pen + $2pencil = $8 final

v2+4v-21=0 (solve by factoring)
Answer: (v + 7)(v -3)
Step-by-step explanation:
(v +7)(v -3)
v x v = v^2
v x -3 = -3v
7 x v = 7v
7 x -3 = -21
v^2 -3v +7v -21 = v^2 +4v -21 = 0
Answer:
The answer is (v - 3)(v + 7).
Step-by-step explanation:
First, you have to elaborate it :
v² + 4v - 21 = 0
v² - 3v + 7v - 21 = 0
Next, you have to collect like terms :
v(v - 3) + 7(v - 3) = 0
(v - 3)(v + 7) = 0
