Which of the following sets of ordered pairs represents a function?
A: {(−4, −3), (−2, −1), (−2, 0), (0, −2), (0, 2)}
B: {(−5, −5), (−5, −4), (−5, −3), (−5, −2), (−3, 0)}
C: {(−4, −5), (−4, 0), (−3, −4), (0, −3), (3, −2)}
D: {(−6, −3), (−4, −3), (−3, −3), (−2, −3), (0, 0)}
Answer:
A set of ordered pairs represents a function if each input (first coordinate) corresponds to one and only one output (second coordinate). In other words, there can't be two different second coordinates for the same first coordinate.
Using this definition, we can determine which of the sets of ordered pairs represents a function:
A: {(-4, -3), (-2, -1), (-2, 0), (0, -2), (0, 2)}
The input -2 has two different outputs (-1 and 0), and the input 0 also has two different outputs (-2 and 2). Therefore, this set does not represent a function.
B: {(-5, -5), (-5, -4), (-5, -3), (-5, -2), (-3, 0)}
The input -5 has four different outputs (-5, -4, -3, and -2), but each of the other inputs has only one output. Therefore, this set does not represent a function.
C: {(-4, -5), (-4, 0), (-3, -4), (0, -3), (3, -2)}
The input -4 has two different outputs (-5 and 0), but each of the other inputs has only one output. Therefore, this set does not represent a function.
D: {(-6, -3), (-4, -3), (-3, -3), (-2, -3), (0, 0)}
Each input has only one output, so this set represents a function.
Therefore, the set of ordered pairs that represent a function is D: {(-6, -3), (-4, -3), (-3, -3), (-2, -3), (0, 0)}.

21.36/2 - 8.98/2 = 6.19
Answer:
$6.19
Step-by-step explanation:
You want the difference in price per pound between the cost of salmon at store B and the cost at store A.
Cost per poundThe cost per pound is found by dividing the cost by the corresponding number of pounds. The difference in cost will be the difference of those quotients.
cost at Store B - cost at Store A = ($21.36/(2 lb)) -($8.98/(2 lb))
= ($21.36 -8.98)/(2 lb) = $6.19/lb
It is $6.19 per pound more expensive to buy salmon at Store B than at Store A.

Laila participated in a dance-a-thon charity event to raise money for the Animals are Loved Shelter. The graph shows the relationship between the number of hours Laila danced, x, and the money she raised, y.
Determine the slope and explain its meaning in terms of the real-world scenario.
The slope is 6, which means that the amount the student raised increases by $6 each hour.
The slope is one sixth, which means that the amount the student raised increases by $0.34 each hour.
The slope is 12, which means that the student will finish raising money after 12 hours.
The slope is 20, which means that the student started with $20.
Answer: The answer is A. The slope is 6, which means that the amount the student raised increases by $6 each hour.
Step-by-step explanation: I hope this help.
The correct interpretation is option (A) The slope is 6, which means that the amount the student raised increases by $6 each hour.
What is the Linear equation?A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.
The slope is 6, which means that the amount of money Laila raised increases by $6 for every hour she danced. In other words, for each additional hour of dancing, Laila raised an additional $6 in donations.
This indicates a linear relationship between the number of hours Laila danced and the amount of money raised.
The y-intercept is 20, which means that when Laila did not dance at all, she still managed to raise $20 for the Animals are Loved Shelter.

Answer:
1.5 miles less
Step-by-step explanation:
Step 1: Find equation for Alexanda
We can see from Fabian's equation that there is a linear relationship between miles (y) and gallons (x).Fabian's equation is in the slope-intercept form (y = mx + b), where m is the slope and b is the y-intercept. Although we're not given the equation for Alexandra, we can find it using the slope formula, which is[tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex].
If we allow (8, 345.6) to be our x1 and y1 and (12, 518.4) to be our x2 and y2, our slope is
[tex]m=\frac{(518.4-345.6)}{(12-8)}\\ m=\frac{172.8}{4}\\ m=43.2[/tex]
Now, we must find the y-intercept by plugging in 43.2 for m, 8 for x, and 345.6 for y into the general slope-intercept form and solving for b:[tex]345.6=43.2(8)+b\\345.6=346.6+b\\0=b[/tex]
Thus, the equation for Alexandra is y = 43.2x
Step 2: Plug in 1 for x for both Fabian and Alexandra's equations and subtract
Since x is is gallons, we plug in 1 for x for each equation and subtract Fabian's miles from Alexandra's miles to find how many miles less can Fabian drive one 1 gallon of gas than Alexandra:
Fabian: y = 41.7(1) = 41.7
Alexandra: y = 43.2(1) = 43.2
Difference of Alexandra and Fabian's miles: 43.2 - 41.7 = 1.5

2√(4)√(5/4)3√(1)√(2/1)2√(1)√(3/1)How do we approximate the square roots using the perfect squares?To approximate the square roots using the perfect squares method, we need to find the largest perfect square that is less than each of the given terms, and then simplify.
For 2√5:
The largest perfect square less than 5 is 4, so we can write 2√5 as 2√(4)√(5/4).
Simplifying, we get:
2√(4)√(5/4)
= 2(2)√(5/4)
= 4√(5/4)
= 4√5/√4
= 4√5/2
= 2√5.
For 3√2:
The largest perfect square less than 2 is 1, so we can write 3√2 as 3√(1)√(2/1).
Simplifying, we get:
3√(1)√(2/1)
= 3(1)√(2/1)
= 3√2/√1
= 3√2.
For 2√3:
The largest perfect square less than 3 is 1, so we can write 2√3 as 2√(1)√(3/1).
Simplifying, we get:
2√(1)√(3/1)
= 2(1)√(3/1)
= 2√3/√1
= 2√3.

A product-testing group compares two brands of trail mix to determine the number of raisins per ounce of mix. Two pounds of each brand's mix is separated into 32 one-ounce servings. The medians of the data distributions for Brand a and Brand B are -- Responses: A-equivalent to 12. B-greater than 12. C- less than 12. D- unable to be determined from the graph.
The data distribution for brand A is slightly skewed left while the data distribution for brand B is close to symmetric.
The medians of the data distributions for Brand A and Brand B are: greater than 12
How to identify the distribution pattern?Some of the terms in normal distribution spread are:
Right skewed: This is clearly where the mean is greater than the median. The mean overestimates the most common values in a positively skewed distribution.
Left skewed: This is clearly where the mean is less than the median.
Symmetric: In a symmetrical distribution, the mean, median, and mode are all equal.
1) Brand A distribution is left skewed because because there is a cluster of data on the right side
Brand B distribution is symmetric
2) The median of brand A will be the 16th and 17th dots which gives us:
(12 + 14)/2 = 13
Meanwhile, the median of brand B is:
(11 + 13)/2 = 12

Find the 25th term.
2, 10, 18, 26, 34, ...
25th term = [?]
an = a1 + (n - 1)d
Substituting the values
an = 2 + (n - 1)8
We have to find the 25th term n = 25
a25 = 2 + (25 - 1)8
a25 = 2 + (24)8
a25 = 2 + 192
a25 = 194
======================================================
Explanation:
The gap between adjacent terms is 8.
2+8 = 1010+8 = 1818+8 = 2626+8 = 34etcThe long way to get the answer would be to keep adding 8 to each term to generate the next one. You'd need to do this 20 times. There are 5 terms here already, so you need 25-5 = 20 more operations of "add 8".
I don't recommend this option. I recommend the shortcut mentioned in the next section.
--------
The shortcut would be to find the nth term of the arithmetic sequence
[tex]a_1 = 2 = \text{ first term}\\\\d = 8 = \text{ common difference}\\\\a_n = \text{ nth term}\\\\a_n = a_1 + d(n-1)\\\\a_n = 2 + 8(n-1)\\\\[/tex]
As a check, plug n = 1 into that formula to get [tex]a_1 = 2[/tex]. Plug n = 2 to get [tex]a_2 = 10[/tex] and so on. I'll leave this check portion for the student to do.
--------
The last step is to plug n = 25 into that formula to determine the 25th term.
[tex]a_n = 2 + 8(n-1)\\\\a_{25} = 2 + 8(25-1)\\\\a_{25} = 2 + 8(24)\\\\a_{25} = 2 + 192\\\\a_{25} = 194\\\\[/tex]
The final answer is 194-------
Extra section (optional):
We can use a spreadsheet to generate the 25 terms. This is to help check the answer.

John puts $70 in a savings account that earns 6% annually. The interest is not compounded. How many years will it take John to make at least $100 in interest?
Answer:
24 years
Step-by-step explanation:
If interest is not compounded, it is called simple interest.
Simple interest is calculated as a percentage of the principal amount and is applied only to the principal.
The formula for simple interest is:
[tex]\boxed{\sf I = Prt}[/tex]
where:
I = Total interest earned.P = Principal amount.r = Interest rate (in decimal form).t = Time (in years).The given values are:
I = $100P = $70r = 6% = 0.06Substitute the given values into the formula and solve for t:
[tex]\implies \sf 100=70 \cdot 0.06 \cdot t[/tex]
[tex]\implies \sf 100=4.2 t[/tex]
[tex]\implies \sf 4.2 t=100[/tex]
[tex]\implies \sf \dfrac{4.2 t}{4.2}=\dfrac{100}{4.2}[/tex]
[tex]\implies \sf t=23.8095238...\;years[/tex]
We need to round up to the next year. Therefore, it will take 24 years for John to make at least $100 in interest.
Answer:
approx. 24 years
Step-by-step explanation:
The formula to find the simple interest is:
[tex]\sf I= \frac{prt}{100}[/tex]
Here,
I ⇒ Interest ⇒ $ 100
p ⇒ principle ⇒ $ 70
r ⇒ rate ⇒ 6
t ⇒ time ( years )
Let us find the time taken using the formula.
[tex]\sf I= \frac{prt}{100}\\\\100=\frac{70*6*t}{100} \\\\100*100=420t\\\\10000=420t\\\\23.8\: years=t\\\\approx. \:24 \:years=t[/tex]
Point A, located at (5, -4) is reflected in the y-axis, resulting in the location of point A'. Which of the following statements is true?
Point A' is located at (-5,-4)
Point A' is located at (-5,4)
Point A is located at (4,5)
Point A' is located at (-4,5)
The correct answer is Point A' is located at (-5, -4).
When a point is reflected in the y-axis, its x-coordinate is negated and its y-coordinate remains the same. Therefore, the x-coordinate of point A changes from +5 to -5, and the y-coordinate remains -4. Hence, the coordinates of A' are (-5, -4).
