Answer: A and E
A function is a relation for which each value from the set the first components of the ordered pairs is associated with exactly one value from the set of second components of the ordered pair.
From all tables, table A, table C and table E could represent a function.
What is function?"It is a relation between input and output values.""In function, for each input there is exactly one output."For given question,
We have been given five tables.
Here, column x represents input values and column y represents the output values.
For table A,
each input value distinct output.
Hence table A could represent a function.
For table B,
there are two outputs -4 and -6 for the input 3.
So, table B could not represent a function.
For table C,
There is distinct output for each input.
So, table C could represent a function.
For table D,
There are four output values for the input 3.
So, table D could not represent a function.
For table E,
There is distinct output for each input.
So, table E could represent a function.
Therefore, table A, table C and table E could represent a function.

3. At a bargain store, Spongebob bought 3 items that each cost the same amount. Patrick bought 5 items that each cost the same amount, but each was $1.50 less than the items that Spongebob bought. Both Spongebob and Patrick paid the same amount of money. What was the individual cost of each person's items?
Answers
Answer: Cost of each item bought by Spongebob = $2.5
Cost of each item bought by Patrick = $1
Step-by-step explanation:
Let x be the cost of each item bought by Spongebob.
Then, cost of each item bought by Patrick = x- 1.50
Then, cost of 3 items bought by Spongebob = 3x
Cost of 5 items bought by Patrick = 5(x-1.50)
If both Spongebob and Patrick paid the same amount of money then
[tex]3x= 5(x-1.5)\\\\\Rightarrow\ 3x=5x-1.5\times5\\\\\Rightarrow\ 3x=5x-7.5\\\\\Rightarrow\ 5x-2x=7.5\\\\\Rightarrow\ 3x=7.5\\\\\Rightarrow\ x=\dfrac{7.5}{3}\\\\\Rightarrow\ x=2.5[/tex]
Cost of each item bought by Spongebob = $2.5
Cost of each item bought by Patrick = $2.5-$1.5=$1
Hence, Cost of each item bought by Spongebob = $2.5
Cost of each item bought by Patrick = $1
Answer: Cost of each item bought by Spongebob = $2.5
Cost of each item bought by Patrick = $1
Step-by-step explanation:
Let x be the cost of each item bought by Spongebob.
Then, cost of each item bought by Patrick = x- 1.50
Then, cost of 3 items bought by Spongebob = 3x
Cost of 5 items bought by Patrick = 5(x-1.50)
If both Spongebob and Patrick paid the same amount of money then
Cost of each item bought by Spongebob = $2.5
Cost of each item bought by Patrick = $2.5-$1.5=$1
Hence, Cost of each item bought by Spongebob = $2.5
Cost of each item bought by Patrick = $1
Write the equation of the line that passes through the points (3, -4) and (-3, 0) in slope-intercept form.
Answers
Step 1: Use the slope formula y₂ - y₁/x₂ - x₁ to find the slope.
[tex]\frac{0 - (-4)}{-3 - 3}\\ \\\frac{4}{-6} = -\frac{2}{3}[/tex]
Step 2: Plug the slope we found and one point into the slope-intercept formula, y = mx + b.
[tex]y = mx + b\\\\0 = -\frac{2}{3}(6) + b\\\\0 = -4 + b\\\\4 = b[/tex]
Step 3: Put it all together.

Given data
The total number of pumpkin is 8+6+15= 29 pumpkin
total cost of pumpkin=
8*3.5=$28
6*8=$48
15*1=$15
total is $28+$48+$15= $91
the total amount sold is not up to $95, so she will not receive the $10 bonus
But she will receive

Answers
Answer:
12:7
Step-by-step explanation:
Total number of kids = 76
Total number of kids that ordered chicken nuggets = 28
Total number of kids that did not order chicken nuggets = 76 - 28
= 48
The ratio of kids who did not order chicken nuggets to the number of kids who did is:
= 48 : 28

Step-by-step explanation:
first you have to make this an improper fraction my multiplying -3 by 11 then add the product of that to 6 and put it all over 11
[tex]-3\frac{6}{11}[/tex] → [tex]-\frac{39}{11}[/tex]
once you get this you have to do the reciprocal of this to get them to equal 1
[tex]-\frac{39}{11}[/tex] → [tex]-\frac{11}{39}[/tex]
then multiply the number by the reciprocal
[tex]-\frac{39}{11}* -\frac{11}{39}=\frac{429}{429}=1[/tex]

Answer:
use slope intercept form to find the x intercept
y = Mx +b
Step-by-step explanation:
x+4y=7
4y= -x+7
y= -1/4x +7/4
so when this line is on the x intercept.. then y =0 soooo plug in zero for y and solve
0= -1/4x + 7/4
-7/4 = -1/4x

Timothy and Alondra are cutting strips of poster paper for an art project.
Timothy cut 10 strips of poster paper that are each 3 feet inches long.
Alondra cut 10 strips of paper that are same length as Timothy’s strips of paper, but measured them as 106.68 centimeters long.
If Alondra cuts a strip of poster paper that is 220 centimeters long, what is the approximate length of the strip in feet that Timothy will measure.
please answer, fast!
Answers
Answer:
answer B
Step-by-step explanation:
I
there's 3 feet and 9 inches of paper on timothy's side
alondra cuts the zame amount of strips at 106.68m
there are 2.54 centimeters in one inch.
there are 12 inches in a foot
12 ×3 is 36 plus 9 is 45 inches
now, divide 106.68 by 2.54 to get 42 inches (we have 3 left over
if we subtract 220 by 106.68 we get 113.12
2.54 centimeters equals 1 inch, divide 113.12 to get 44.6
convert this to feet and we get 3 feet and 8 inches
3 feet 8 onches plus 3 feet 10 inches is 7.7 (by rounding)

Each gallon of gasoline costs $2.35. The equation y=2.35x can be used to represent this situation.
What is the constant of proportionality? Express your answer in decimal form.
Answers
Answer:
For every gallon of gas added to the tank, the buyer is charged $2.35
The constant of proportionality of the given equation y = 2.35x will be 2.35.
What is the equation?There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
More than one variable may be present inside a linear equation. An equation is said to be linear if the maximum power of the variable is consistently unity.
Let's x ∝ y
Then x = ky where k will be constant of proportional.
k = x/y which means when two variables are divided which were in proportion it will create a constant proportional.
So,
y /x = 2.35 will be constant of propotional.
Hence "The constant of proportionality of the given equation y = 2.35x will be 2.35".
