Currently, you earn $10 a week for doing chores around the house. Your father realizes that you are trying to save up, and offers you the following deal. You can either be paid the $10, or you can pull two bills from a brown paper bag. In the bag there are two $1 bills, two $5 bills, and a $10 bill. For example, you might pull out a $1 bill followed by a $5 bill, and earn only $6. Or you might pull out the $10 bill followed by a $5 bill and earn $15. If you were given this option every week, what would be better for you to do in the long run? Is pulling two bills from the paper bag a great way to make money?

Explain why a V-shaped graph does not represent a linear function.
Answers
A V-shaped graph belongs to an absolute value function or a piecewise function, never to a linear function (these are graphed only with a single line).
Why a V-shaped graph does not represent a linear function?This is really trivial question.
A linear function has a graph that is a straight line.A V-shaped graph is not a straight line, is a V.So the answer is really trivial, as you can see.
But let's explain it a little bit more.
The only functions that have V-shaped graphs are piecewise functions (formed of two linear equations) or absolute value equations, neither of these are exactly linear (but they are made of "linear like parts").

5. Which of the equations show x and y DIRECTLY proportional to each relationship? For every one that does provide the constant of proportionality
Answers
A direct proportional relation can always be express as an equation of the form:
[tex]y=kx[/tex]where k is the constant of proportionality. (This means that y has to be the result of multiplying a number by x)
Now, let's see at the option we have.
a)
Solving the equation for y we have:
[tex]\begin{gathered} 2x+2y=0 \\ 2y=-2x \\ y=-\frac{2}{2}x \\ y=-x \end{gathered}[/tex]Since we can write the equation in the form as a direct proportional relationship we conclude that option a shows a directly proportional relationship and that the constant is -1.
b)
For this case we have the equation:
[tex]x=.125y[/tex]From it we already can see that this means that x is directly proportional to y and that the constatn of porportionality is 0.125.
Now if we want we can solve the equation for y, then we have:
[tex]\begin{gathered} y=\frac{1}{.125}x \\ y=8x \end{gathered}[/tex]this equation shows that y is directly proportional to x and that the constant of proportionality is 8.
Notice that the the constant of proportionality changes if we write the relation as x directly proportional to y or if we write it as y directly proportional to x. Either way the relation express the same and it is directly proportional.
c) and d)
For this equations that we have a division in which one of the variables is the divisor (or the denominator); this means that the equation show a relation between x and y but their are not directly proportional. In fact this means that the equations show an inversely proportional relations.

Answers
The linear equations are x + y = 10 and (11.90)x + (13.10)y = (12.86)(10) and the value of x and y are 2 and 8 respectively.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
A coffee distributor needs to mix a(n) Queen City coffee blend that normally sells for $11.90 per pound.
Let x and y be the quantity of Queen City coffee (lbs) and the quantity of Arabian Mocha coffee (lbs)
From the data given;
The equations can be framed:
x + y = 10
(11.90)x + (13.10)y = (12.86)(10)
After solving the substitution method:
x = 2
y = 8
Thus, the linear equations are x + y = 10 and (11.90)x + (13.10)y = (12.86)(10) and the value of x and y are 2 and 8 respectively.

The total profit from the Spanish club fundraiser varies directly with the number of dinner tickets sold. If the sale of 14 tickets results in a profit of $175, how many tickets must be sold to reach the fundraising goal of $600?
Answers
Spanish club has 48 tickets which must be sold to reach the fund-raising goal as profit of $600.
What is profit?
In mathematics, the term profit can be explained as the amount which is on the standard cost price. For the profit, the amount of the commodity can be designed by the shopkeeper which is bigger amount as per the cost price.
According to the question, the total profit from the Spanish club fundraiser varies directly with the number of dinner tickets sold.
If the sale of 14 tickets results in a profit of : $175.
Therefore, Profit in 1 ticket = 175/14 = 12.5 dollars
Let us assume 'x' tickets are sold in order to reach the fund-raising goal of $600.
x = (14/175)(600) = 48
x = 48 tickets
Hence, 48 tickets must be sold to reach the fund-raising goal as profit of $600.
