Lorraine writes the equation shown.
x^2 + y - 15 = 0
She wants to describe the equation using the term relation and the term function.
The equation represents:
A relation and a function
A relation but not a function
A function but not a relation
Neither a function or a relation
A function is a special relation whose every input corresponds with a single output. To be a function, each input is allowed to pair with only one output element.
[tex] x^2+y-15=0\\ Adding \; 15 \; subtracting \; x^2\; on\; both\; sides\\ \\ y=-x^2+15 [/tex]
For a parabola equation like above, there is no restriction in the domain. For every x value there is a unique y value.
Conclusion:
The equation [tex] x^2+y-15=0 [/tex] is BOTH a function and a relation!

Last year, a property manager bought five identical snow shovels and six identical bags of salt. The total cost of the snow shovels was $172.50, before tax and each bag of salt cost $6.20, before tax.
This year, the property manager bought two identical snow shovels and four identical bags of salt. The total cost of the snow shovels was $70.38, before tax, and the total cost of the bags of salt was $26.04, before tax.
Determine the item with the greatest percent increase in the rice from last year to this year. Be sure to include to the precent increase of this item to the nearest percent.
The item with the greatest percent increase in price from last year to this year is the bag of salt, with a 5% increase.
The item with the greatest percent increase in price from last year to this year is the bag of salt, with a 5% increase, compared to the 2% increase for the snow shovels.
To determine the item with the greatest percent increase in price from last year to this year, we need to calculate the price per unit for each item both years and compare the percentage increases. Last year, the property manager bought five snow shovels for $172.50, meaning each shovel costs $34.50 ($172.50 \/ 5). This year, two snow shovels cost $70.38, so each costs $35.19 ($70.38 \/ 2). To find the percent increase for the snow shovels, we subtract last year's price from this year's price, divide by last year's price, and multiply by 100: (($35.19 - $34.50) \/ $34.50) \times 100 = 2% (rounded to the nearest percent).
For the bags of salt, each cost $6.20 last year. This year, the total cost for four bags was $26.04, so each costs $6.51 ($26.04 \/ 4). Using the same formula for percent increase, we get the percent increase for the bags of salt: (($6.51 - $6.20) \/ $6.20) \times 100 = 5% (rounded to the nearest percent).
Therefore, the item with the greatest percent increase in price from last year to this year is the bag of salt, with a 5% increase.

Formulate a system of equations to represent this situation, with f = the amount of money that Frank spent and r = the amount of money that Rachel spent. Frank and Rachel spent a total of $15.75. If Rachel spends twice as much money as Frank, how much money did they each spend?
A)
B)
C)
D)
Rachel and Frank spends $10.5 and $5.25 respectively.
It is given to us that
f is the amount of money that Frank spent and
r is the amount of money that Rachel spent.
Frank and Rachel together spent a total of $15.75.
Rachel spends twice as compare to Frank
The equation that represents this situation:
1. f + r = $15.75
2. r = 2f
Substituting r = 2f in equation 1.
f + r = 15.75
f + 2f = 15.75
3f = 15.75
f = 5.25
Substituting f = 5.25 in equation 2.
r = 2f
r = 2(5.25)
r = 10.5
Thus, Rachel spends $10.5 and Frank spends $5.25.

Create a pattern with the rule n+3
Answer:
6, 7,8,9,10
When we set n= 3
Step-by-step explanation:
Step one
The rule n+3 states that we are allowed to add 3 to any number starting from n
Step two
To practically express this rule
Say n = 3
The pattern is
= 3+3, 4+3, 5+3,6+3,+3
= 6, 7 ,8 ,9 ,10
In this exercise we have to create a pattern by placing a rule, so this pattern is:
[tex]n+3=5, 6, 8, 10...[/tex]
We know that it is not an unknown that can be any value, so the values of n will only be prime numbers and its formula can be described as:

how long will it take you to drive 135 miles at a speed of 45 miles per hour
Answer: The required time taken to drive 135 miles is 3 hours.
Step-by-step explanation: We are given to find the time taken to drive 135 miles at a speed of 45 miles per hour.
We will be using the UNITARY method to solve the problem.
We have
Time taken to drive 45 miles = 1 hour.
So, time taken to drive 1 mile will be
[tex]\dfrac{1}{45}~\textup{hour}.[/tex]
Therefore, the time taken to drive 135 miles is given by
[tex]\dfrac{1}{45}\times135=3~\textup{hours}.[/tex]
Therefore, the required time taken to drive 135 miles is 3 hours.

The first pentagon is dilated to form the second pentagon. Drag and drop the answer to correctly complete the statement. The scale factor is . A pentagon with a side length of 4. An arrow points to a larger pentagon with a side length of 5
Final answer:
To find the scale factor for the dilation of a pentagon from a side length of 4 to a side length of 5, divide the new dimension by the original dimension, resulting in a scale factor of 1.25.
Explanation:
The question asks about finding the scale factor used to dilate a pentagon from a side length of 4 to a side length of 5. To find the scale factor, we compare the new dimension to the original dimension. In this case, the side length of the second pentagon is 5, and the side length of the first pentagon is 4. To find the scale factor, we divide the new dimension by the original dimension, which is 5/4. Hence, the scale factor is 1.25.
To clarify, the scale factor is determined by dividing the new dimension (5) by the original dimension (4), yielding 5/4. Therefore, the scale factor is indeed 1.25. This indicates that each side of the pentagon has been multiplied by 1.25 to achieve the dilation from a side length of 4 to a side length of 5.

An exponential number is the product of the base multiplied by itself "n" times.
A number that is formed by repeated multiplication by the same factor is called an exponential number or a power. It is typically represented in the form "a^n," where "a" is the base and "n" is the exponent. The exponent indicates how many times the base is multiplied by itself.
For example:
2³ is read as "2 raised to the power of 3," and it means 2 × 2 × 2 = 8.
3² is read as "3 raised to the power of 4," and it means 3 ×3 × 3 × 3 = 81.

The ratio of lipsticks to eyeshadow is 1:9. The ratio of eyeshadow to mascara is 3:2. Given I have 3 more eyeshadows than mascaras how many lipsticks do i have?
We can find L using [tex]\( L = \frac{1}{9}E \)[/tex]:
[tex]\[ L = \frac{1}{9} \times 9 = 1 \][/tex]
So, you have 1 lipstick.
To solve this problem, we'll work step by step.
Let's denote:
- L as the number of lipsticks.
- E as the number of eyeshadows.
- M as the number of mascaras.
Given:
1. The ratio of lipsticks to eyeshadows is 1:9, which means L:E = 1:9 .
2. The ratio of eyeshadow to mascara is 3:2, which means E:M = 3:2 .
3. You have 3 more eyeshadows than mascaras, so E = M + 3.
First, we'll use the information to establish the relationship between L, E, and M.
From the ratio L:E = 1:9, we can express L in terms of E:
[tex]\[ L = \frac{1}{9}E \][/tex]
From the ratio E:M = 3:2, we can express M in terms of E:
[tex]\[ M = \frac{2}{3}E \][/tex]
Now, we can substitute E = M + 3 into the equation for M:
[tex]\[ M = \frac{2}{3}(M + 3) \][/tex]
3M = 2(M + 3)
3M = 2M + 6
M = 6
Now that we have found M, we can find E using E = M + 3:
E = 6 + 3 = 9
Now that we have found E, we can find L using [tex]\( L = \frac{1}{9}E \)[/tex]:
[tex]\[ L = \frac{1}{9} \times 9 = 1 \][/tex]
So, you have 1 lipstick.

A cross section of an attic is shaped like a trapezoid. It has an area of 37.4 square meters one base is 6.4 meters and the other base is 12.3 meters long. What is the height of the cross section
Final answer:
To find the height of the trapezoid, use the formula for the area of a trapezoid which is (1/2) x (sum of bases) x height. Calculate the height by substituting the given values for the area, and the lengths of the bases into the formula to find the height as 4 meters.
Explanation:
Area of a trapezoid = (1/2) x (sum of bases) x height
Given area = 37.4 m², base1 = 6.4 m, base2 = 12.3 m
37.4 = (1/2) x (6.4 + 12.3) x h
37.4 = (1/2) x 18.7 x h
h = (37.4 x 2) / 18.7 = 4 meters
Louise is walking 12 miles to raise funds for a local cause. If she has completed

12 x 3/4 = 36/4 = 9
she has walked 9 miles
Final answer:
Louise has walked 9 miles after completing 3/4 of her 12-mile fundraising walk. Thus, option b is correct.
Explanation:
The student's question asks how many miles Louise has walked if she has completed 3/4 of her 12-mile fundraising walk. To find the distance walked, multiply the total distance by the fraction completed. So, Louise has walked 3/4 of 12 miles, which is calculated as follows:
Multiply 3/4 by 12.
3/4 * 12 = 9.
Thus, Louise has walked 9 miles.
