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)}.

2x² - 7x + 3 = 0

2. Use the quadratic formula

Once in standard form, identify a, b, and c from the original equation and plug them into the quadratic formula.

3. Simplify

1. Evaluate the exponent

2. Multiply the numbers

3. Subtract the numbers

4. Evaluate the square root

5.  Multiply the numbers

6. Separate the equations

To solve for the unknown variable, separate it into two equations: one with a plus and the other with a minus.

7.  Solve

Rearrange and isolate the variable to find each solution

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).

Answer:

y = (-1/5)x

Step-by-step explanation:

The equation that represents a proportional relationship, or a line, is

y = k x , where is the constant of proportionality.

y = 2x + 5 (N0)

y equals one fifth times x minus 7 -------  y = (1/5)x -7  (No)

y equals negative one fifth times x ------y = (-1/5)x  (Yes)

y = −5 (No)

Answer:D -> y equals one fifth times x minus 7

Step-by-step explanation: In a proportional relationship, when x is multiplied by a constant, then y will also be multiplied by the same constant. This means that the ratio between x and y remains constant throughout. In the given options, the equation "y equals one-fifth times x minus 7" follows the proportionality rule because when x is multiplied by 5, then y is also multiplied by 5, which means that the ratio between x and y remains constant throughout. Therefore, the correct option is "y equals one-fifth times x minus 7

Answer: C 9/20

Step-by-step explanation:

the odds the yankees don't get rain is 3/5. The odds they win are 3/4. 3/5x3/4=9/20

Answer:

(C), 9/20

Step-by-step explanation:

If the probability that the next Yankees game will be rained out is 2/5, this must mean than, theoretically, two times out of five, the game will be rained out.

This also means than three times out of five, it will not be rained out, so the probability that it will not be rained out is 3/5 (1-(2/5)=3/5)

We know that the probability that they will win their next game is 3/4.

We need to find the probability that it doesn't rain and the Yankees win. TO do this, we multiply both probabilities together. So, we have:

[tex]\frac{3}{5} *\frac{3}{4} =\\\\\frac{9}{20}[/tex]

So, the answer is (C), 9/20.

Answer:

The equation that represents a linear function is:

y = 5x - 6

Step-by-step explanation:

This equation has a constant rate of change, which means that for every unit increase in x, there is a consistent and constant increase or decrease in y. This is a characteristic of linear functions, where the relationship between x and y is a straight line.

y = 5x - 6 is represents a linear function.

A linear function is a type of function in which the highest power of x is one. The graph of a linear function has only one solution, and intercept x - axis at only one point and intercepts y - axis at only one point as well.

Generally, the equation of a linear function is given as;

y = mx + c

where;

The graph of a linear function is usually directly proportional, either increasing or decreasing.

From the options, only the function, y = 5x - 6 is a linear function.

Answer:

A B D F

Step-by-step explanation:

quadratic equation normally comes with squares

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

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

Answer: It is D.  Carl had 8 pounds of ice after 2 minutes, didn't use any ice for 4 minutes, and then used one half pound each minute for 6 minutes.

Step-by-step explanation:

Answer:

Answer is option B

Step-by-step explanation:

48:6=8:1. applies to 64:8=8:1

Answer:b

Step-by-step explanation:

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.

The 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]

Extra section (optional):

We can use a spreadsheet to generate the 25 terms. This is to help check the answer.

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.

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.

The mixed fraction approximation for the given terms using the perfect squares method are:

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.

Answer:

1.5 miles less

Step-by-step explanation:

Step 1:  Find equation for Alexanda

[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]

[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
