Tell whether each graph is a function and justify your answer. Which graph is not a good representation of a real-world situation? Explain.
Answers
Using the function concept, it is found that:
Graph B is a function because each value of x corresponds to exactly one y-value.In a function, one value of the input can be related to only one value of the output.
In a graph, it means that for each value of x(horizontal axis), there can be only one respective value of y(vertical axis).In this problem, at Graph A, when x = 5, for example a vertical line crosses the function 3 times, hence there are 3 respective values of y for x = 5, and the same is valid for other values of x, hence it is not a function.
At Graph B, for each value of x, there is only one value of y, hence it is a function.
Hence:
Graph B is a function because each value of x corresponds to exactly one y-value.

Hey there!
“63 + 49”
21(3 + 2)
= 21(3) + 21(2)

Option A. isn’t the answer because the equation for that is: 63 + 42
7(9 + 7)
= 7(9) + 7(7)
= 63 + 49
= 112
Option B. could possibly be your answer
9(7 + 6)
= 9(7) + 9(6)

Roberto is a fan of the Los Angeles Angels baseball team. Since he works at night he only
goes to day games. Last year he attended all 16 home day games and saw his team win 11
and lose only 5 games, for a winning percentage of 68.8%. In their other games the team won
69 and lost 77, for a winning percentage of 47.3%.
Even though the p-value for a test
comparing these winning percentages is very small, explain how confounding prevents us
from concluding that Roberto’s attendance at those games is the cause of the Angels success
in those games.
Answers
Step-by-step explanation:
There are other factors than Roberto coming that could have affected the outcome of the game. For example, maybe the night games were against better teams to generate better ratings in prime time. Moreover, maybe the Angels do better at home due to home-field advantage. There are many factors such as these that could explain why Roberto witnessed such a high win rate at the games he went to, so it cannot be concluded that Roberto's attendance caused the Angels to win.

x=19
Step-by-step explanation:
The 2 angles are same side interior angles, so together they add to 180 degrees. So you can make this equation:
6x + 4 + 4x - 14 = 180
10x - 10 = 180 (Combine like terms)
10x = 190 (add 10 to each side)
x = 19 (divide both sides by 10)
So just add them together and make them equal to 180°
6x + 4 + 4x - 14 = 180
Add like terms
10x - 10 = 180
10x = 190
x = 19

y = 5/2
The x-intercept is found by setting y=0 and dividing by the coefficient of x.

Shirt Circuit Graphic Tees has fixed expenses of $25,560 for the production of their
t-shirts. They have a variable expense of $4.50 for each t-shirt that they
produce, and they sell their t-shirts for $22.50 each.
How many t-shirts does Shirt Circuit Graphic Tees have to sell to reach their
breakeven point?
Answers
Answer:
Step-by-step explanation:
Cost price = fixed expenses + variable expenses× number of products (x)
Selling price = total cost price + profit
At break even point,
Profit = 0
Therefore, total selling price = total cost price
X(22.50)= 25560 + x(4.50)
(22.50 - 4.50)x = 25560
18x= 25560
X = 1420

How can you tell if you’re finished solving a polynomial division problem ?
Answers
Answer:
Hope this helps :D
Step-by-step explanation:
Here are the steps in dividing polynomials using the long method:
Arrange the indices of the polynomial in descending order. Replace the missing term(s) with 0.
Divide the first term of the dividend (the polynomial to be divided) by the first term of the divisor. This gives the first term of the quotient.
Multiply the divisor by the first term of the quotient.
Subtract the product from the dividend then bring down the next term. The difference and the next term will be the new dividend. Note: Remember the rule in subtraction "change the sign of the subtrahend then proceed to addition".
Repeat step 2 – 4 to find the second term of the quotient.
Continue the process until a remainder is obtained. This can be zero or is of lower index than the divisor.
If the divisor is a factor of the dividend, you will obtain a remainder equal to zero. If the divisor is not a factor of the dividend, you will obtain a remainder whose index is lower than the index of the divisor.
When a divisor has more than one term or if the divisor is a polynomial containing more than one term, the four steps used to divide whole numbers— (divide, multiply, subtract, bring down the next term)—form the repetitive procedure for the polynomial long division.

of folded paper for a total of $54. How much does each roll cost? How much does each
package of folded paper cost?
Answers
Answer:
Rolls $6, Folded $4
Step-by-step explanation:
Minh: 6r + 2f = 44
Mikayla: 3r + 9f = 54
Multiply Mikayla's x 2: 6r + 18f = 108
Subtract Minh: 6r + 2f = 44
16f = 64
f = 4, Folded paper is $4.
Substitute 4 for f into one of the equations.
6r + 2(4) = 44
6r + 8 = 44
6r = 36

Answers
Answer:

Step-by-step explanation:
the money he spent in total is 9.53 subtract it to 12.80
The amount of money left after he purchased his lunch is $3.27.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that Josh had $12.80 to spend for lunch. For lunch, he purchased two hamburgers that cost $2.75 each, cheese fries that cost $1.85, and a drink that cost $2.18.
The amount of money left will be calculated as,
Money left = 12.80 - [(2 x 2.75 ) + 1.85 + 2.18]
Money left = 12.80 - 9.53
Money left = $3.27
Therefore, the amount of money left after he purchased his lunch is $3.27.
