• At store A, 3 pounds of apples cost $12.
• At store B, the cost is given by y = 2x where y is the cost in dollars and x is the number of pounds of apples.
• The cost of apples at store C is shown in the graph.
(don't worry about the graph I know how to do this one)
Answer the questions to find out which store's apples are the least expensive.
2. What is the unit price of apples at store B? How did you use the equation to find the unit price? (2 points)
Answers
Answer:
The unit price is the cost per unit of an item or the cost/price for each item.
1) 4$ per pound. By simplifying the proportion (constant ratio) between the cost, and the pounds of apples. 3 pounds of apples cost 12$ → 3/3 pounds of apples cost 12/3$ → 4 dollars for every pound.
2) 2$ per pound. By evaluating the rate of change (change in the y over x or dependent variable over independent) in the equation: y = 2x. y is the cost in dollars, and x is the pounds of apples. So there are 2 pounds (weight) of apples for every dollar.
3) 3$ per pound. Given a graph with a y scaled by 3, and an x scaled by 1 with a graph y = x or 1 unit up for every unit right. This must be equivalent to y = 3x. Where y is labeled as the cost in dollars, and x as the weight in pounds. So there are 3 dollars for every pound of apples.
4) Store B. Because 2 is less than 3 which is less than 4.

Rafi had a board that was 15 1/2 feet long. He cut three pieces off the board that are each 3 7/8 feet long. How much of the board is left?
Answers
Answer:
Step-by-step explanation:
To answer this question, first we need to figure out how much of the board Rafi cut off.
To do this, we need to multiply the length of each piece by the number of pieces he cut off.
3 7/8 = 3.875
3.875 * 3 = 11.625
Now, because we knew Rafi cut off 11.625 feet off of the board, we just need to subtract this length from the length of the entire board to find the remaining length.
15 1/2 = 15.5
15.5 - 11.625 = 3.875
There is 3.875 feet or 3 7/8 of the board left.

What is x?
Answers
Answer:
x = 4
Step-by-step explanation:
55x + 10 = 230
=> 55x = 230 - 10
=> 55x = 220
=> x = 4
Therefore, x = 4.
Hoped this helped.
Answer:
x= 4
Step-by-step explanation:
solving equation step-by-step.
55x + 10 = 230
Subtract 10 from both sides.
55x + 10 − 10 = 230 − 10
55x = 220
Divide both sides by 55.
55x/55 = 220/55
x= 4
Our Answer: x= 4

N'(-10,-15) is the image of N after a dilation with a scale factor of 5/4, centered at the origin. What are the coordinates of N?
Answers
When the point N is dilated, the coordinate of N changes to N'
The coordinate of point N is (8,12)
How to determine the coordinate of NThe given parameters are:
N' = (10,15)
k = 5/4
To calculate the coordinate of N, we make use of:
N * k = N'
So, we have:
N * 5/4 = (10,15)
Multiply both sides by 4
N * 5 = (40,60)
Divide both sides by 5
N = (8,12)
Hence, the coordinate of point N is (8,12)

how much water should be added to 5 gallons of 50% acid solution to get a 20% solution?
Answers
Answer:
7.5 gallons
Step-by-step explanation:
2.5/5+x=0.2
This question is based on the concept of solving an equation. Therefore, 7.5 gallons of water would be added to 5 gallons of 50% acid solution to get a 20% solution.
Given:
5 gallons of 50% acid solution to get a 20% solution.
According to question,
Let it be x gallons of water should be added to 5 gallons of 50% acid solution to get a 20% solution.
Now, forming the equation, we get,
0.50 ( 5 ) = 0.20 ( x + 5 )
Simplifying the equation.
We get,
2.5 = 0.2x + 1
1.5 = 0.2 x
x = 7.5
Therefore, 7.5 gallons of water would be added to 5 gallons of 50% acid solution to get a 20% solution.

Mallory puts $1.00 in a jar. The following week, she puts 2 times that original amount in the jar. For each of the next six weeks, Mallory continues to double the amout of money she places in her savings jar each week.
Determine if the relationship is linear or nonlinear. Explain your choice using examples with ordered pairs. (week, amount)
Answers
We want to see if the relationship between the number of weeks and the money put in the jar is linear or not, we will see that this is not a linear equation (it is exponential).
So a linear relation is something like:
y = a*x + b
Note that for any value of x, an increase of 1 unit gives:
y = a*(x+ 1) + b = (a*x + b) + a
So for increases of 1 unit in the x-value, we have increases of "a" units on the y-value.
In the given situation we have:
In week 1 she puts $1.00 in the jar.In week 2 she puts $2.00 in the jar (now the jar has $3.00 in it)In week 3 she puts $4.00 in the jar (now the jar has $7.00 on it)In week 4 she puts $8.00 in the jar (now the jar has $15.00 on it)and so on.
Writing that as points we have:
(1, $1)
(2, $3)
(3, $7)
(4, $15)
Notice that for equal increases in the x-value, (increases of 1 unit) we don't equal increases in the y-value (first increases by $2, then by $4, etc...) So this is not a linear equation, this is actually exponential.

The relationship of the ordered pair that represents Mallory savings is a nonlinear relationship.
Let x represents the number of weeks, and y represents the amount put in the jar, each week.
So, we have the following highlights for 6 weeks.
Week 1: (1, 1)Week 2: (2,2)Week 3: (3,4)Week 4: (4,8)Week 5: (5,16)Week 6: (6,32)The ordered pairs can then be represented as:
[tex](x,y) = (1,1)(2,2)(3,4)(4,8)(5,16)(6,32)[/tex]
As the x values increase, the y values increase too, but the y values do not increase at a constant rate.
This means that the relationship is not linear; it is an exponential relationship.
Hence, the relationship is a nonlinear relationship.
