Answer:

A. c = 1.56n

Step-by-step explanation:

In this situation n equals the independent variable. The independent variable means that no matter what the rest of the equation is this will be equal to a certain number.

Now, the correct answer will be A. This is because you will want to multiply 1.56 per pound. When you have a situation like this you know that the amount of money will be added to itself over and over depending on the independent variable. In other words, it will be multiplied by the independent variable.

Lets use this formula:

[tex]x * y = z[/tex]

x = Price of blackberries

y = Number of pounds

z = Total price of blackberries per y pounds.

Now change that to have our variables:

[tex]1.56* n = c[/tex]

or in other words:

[tex]c = 1.56n[/tex]

In the table below I will provide an example of what c will look like depending on n.

[tex]\begin{array}{|c|c|} \cline{1-2} \textbf{n} & \textbf{c} \\ \cline{1-2} 0 & 0 \\ \cline{1-2} 1 & 1.56 \\ \cline{1-2} 2 & 2.13 \\ \cline{1-2} 3 & 4.68 \\ \cline{1-2} 4 & 6.24 \\ \cline{1-2} 5 & 7.80 \\ \cline{1-2} \end{array}[/tex]

As you can see, n will be multiplied by 1.56 to find c. Thus proving our answer is A. [tex]c = 1.56n[/tex]

Answer:

The equation that represents the relationship between the total price and the pounds of blackberries purchased is c = 1.56n.

Step-by-step explanation:

We are given that the price of the blackberries is $1.56 per pound. Therefore, for each pound, the price increases by $1.56.

This is going to be a linear relationship, so our equation is going to be in the form of [tex]y = mx + b[/tex] (this is the parent function for a linear function).

For example, say an individual purchases 3 pounds of blackberries.

Therefore, the initial purchase is going to start at $0 (nothing has been paid for if no blackberries are purchased).

Then, we will have to add the price to itself three times to get our total payment: [tex]1.56+1.56+1.56 = \$4.68[/tex]

After we do this, we can realize that when we add the same value a certain number of times, we can just multiply that value by the amount of times we've added it.

If we purchase the 3 pounds of blackberries, we would multiply $1.56 by 3 to get the total price of the blackberries. So, if we label our pounds of blackberries with a variable, we can see this relationship.

Now, our three pounds of blackberries can be labeled as n. So, we are multiplying $1.56 by n.

[tex]\$1.56 \times n[/tex]

This would give us our total cost, c.

Therefore, our multiplication of $1.56 and n is equal to c, so we can set those equal to each other.

[tex]c=\$1.56\times n[/tex]

Finally, in math, there is a statement that says that when you multiply a constant by a variable, you can drop the multiplication symbol and simply combine the two (for example, [tex]3 \times n[/tex] becomes [tex]3n[/tex]). With this, our equation now becomes:

[tex]c= \$1.56n[/tex]

Therefore, our answer is Choice A.

Answer:

5.36 light years

Step-by-step explanation:

if a light-year = 9.46 x 1012

9.46 x 1012 = 9512.8

4.1 x 1013 = 4153.3

After that you would subtract

9512.8 - 4152.3 = 5.360.5

the real answer is 5.36 light years

So the distance in light years from earth is 5.36 light years

Answer:

strong and negative

Step-by-step explanation:

because the slope of the line is negative, this would be a negative correlation. Also, since all the points are generally next to each other and there seems to be a trend since there are no outliers, this is strong

Step-by-step explanation:

Space diagonals contrast with face diagonals, which connect vertices on the same face (but not on the same edge) as each other. For example, a pyramid has no space diagonals, while a cube (shown at right) or more generally a parallelepiped has four space diagonals.

Answer:

Step-by-step explanation:

Answer:

x: (5/2,0)

y: (0,5)

Step-by-step explanation:

To solve for x-intercept, substitute 0 for y.

-4x+7=2(0)-3

-4x+7=-3

-4x=-10

x=10/4 or 5/2

To solve for y-intercept, substitute 0 for x.

-4(0)+7=2y-3

7=2y-3

10=2y

y=5

Answer:

Step-by-step explanation:

because you said the you 1 ponit for every right ans and -0.25 for incorret ans so 15 right ans would give you 15 ponits and 5 incorret ans would give you -1.25  so i add up  

15+-1.25=13.75 or 55/4
