A linear relationship is given in the table.
x −2 −1 0 1 2
y −12 −7 −2 3 8

What is the slope of the relationship?

A: 5
B: −5
C: one fifth
D: negative one fifth

Answer:

A function is a mathematical relation in which each input (domain value) is associated with exactly one output (range value). In other words, for a relation to be a function, each input can have only one corresponding output. Let's analyze the given pairings:

(a person’s age in years, that same person’s height in inches) - This can be a function because one person's age in years should correspond to a single height in inches.

(a person’s weight in pounds, that same person’s height in inches) - This can also be a function because one person's weight in pounds should correspond to a single height in inches.

(a person’s height in centimeters, that same person’s height in inches) - This can be a function because one person's height in centimeters should correspond to a single height in inches.

(a person’s telephone number, that same person’s height in inches) - This may not necessarily be a function. It's possible for two different people to have the same height in inches but different telephone numbers.

So, the pairings that always describe a function are:

(a person’s age in years, that same person’s height in inches)

(a person’s weight in pounds, that same person’s height in inches)

(a person’s height in centimeters, that same person’s height in inches)

These three pairings meet the criteria of a function, where each input corresponds to a unique output.

The pairing that always describes a function is option C. (a person’s height in centimeters, that same person’s height in inches)

A pairing describes a function when each unique input (domain element) is associated with exactly one unique output (range element). In other words, there should be no ambiguity or multiple outputs for a single input. Let's analyze the given pairings:

1. (a person’s age in years, that same person’s height in inches): This pairing may not always describe a function because multiple people can have the same age, but they might have different heights. So, there can be multiple outputs for the same input (age).

2. (a person’s weight in pounds, that same person’s height in inches): Similar to the first pairing, this may not always describe a function because different people can have the same weight but different heights.

3. (a person’s height in centimeters, that same person’s height in inches): This pairing describes a function because for each unique height in centimeters, there is only one corresponding height in inches.

4. (a person’s telephone number, that same person’s height in inches): This pairing may not always describe a function because multiple people can have the same telephone number, but they might have different heights. So, there can be multiple outputs for the same input (telephone number).

So, the pairing that always describes a function is: (a person’s height in centimeters, that same person’s height in inches)

Answer:

Area of five squares = 1289.09 square units

Perimeter =  194.6 units

Step-by-step explanation:

Area of square and perimeter:

   First find the length of each square, then find the area of each square.

To find the area of five squares, add all the area of each square.

Side of square1 = 27 units

\(\sf Side \ of \ square2 = \dfrac{2}{3}*27=2*9 = 18 \ units\\\\Side \ of\ square3= \dfrac{2}{3}*18=2*6=12 \ units\\\\Side \ of \ square4=\dfrac{2}{3}*12=2*4=8 \ units\\\\Side \ of \ square5=\dfrac{2}{3}*8=\dfrac{16}{3}=5.3 \ units\)

Area of square1 = 27*27 = 729 square units

Area of square2 = 18*18 = 324 square units

Area of square3 = 12*12 = 144 square units

Area of square4 = 8*8 = 64 square units

Area of square5 = 5.3*5.3 = 28.09 square units

Area of five squares = 729 + 324 + 144 + 64 +28.09

                                  = 1289.09 square units

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Perimeter of the composite figure = (27 + 27+27+9) + (18+18+6) +(12+12+4) + (8+8+2.7)+ (5.3+5.3+5.3)

                                                         = 90 + 42 + 28 + 18.7 + 15.9

                                                          = 194.6 units

Answer:

$2.76

Step-by-step explanation:

Price per pound times the number of pounds Ginny bought

Bananas:

2.2*0.49 = 1.078 -> 1.08

Grapes:

1.3*1.29 = 1.677 -> 1.68

Now, to find the total cost of both, add the prices together

1.08 + 1.68 = 2.76

Answer:

$2.76

Step-by-step explanation:

one pound of bananas cost $0.49 , multiply this cost by 2.2 to find the cost at this weight.

2.2*0.49=1.078=1.08

1.3*1.29=1.677=1.68

1.08+1.68=2.76

Change in y OVER change in x

Answer:

\(y = 1x + 0\)

Or, simplified:

\(y = x\)

Step-by-step explanation:

It's a very simple diagram but basically b is where the line cuts into the vertical y line (so in this case 0). m is then how many x there are per y. In this case it's just one.

Answer:

y=x

Step-by-step explanation:

y= mx+b

Pick any points that are on the line; for example (1,1) and (2,2)

for (x1=1, y1=1) and (x2=2, y2=2)

m = (y2-y1) /(x2-x1) = (2-1)/(2-1) = 1/1 = 1

If slope m = 1 then the equation is y = x+b now

Pick any point that is on the line again and substitute the coordinate in our equation to find b (the y-intercept) ; for example point (0,0) is on the line.

y = x+b, for (x=0, y=0) is

0 = 0 +b

0 =b

The equation in the slope intercept form of the given line is y = x, because the slope m=1 and the y-intercept , b=0
