Students are selling raffle tickets for a school fundraiser. They collect $24 for every 10 raffle tickets they sell.
a. Suppose is the amount of money the students collect for selling raffle tickets. Write an equation that reflects the relationship between and .
b. Label and scale the axes and graph this situation with on the vertical axis and on the horizontal axis. Make sure the scale is large enough to see how much they would raise if they sell 1000 tickets. (LOOK AT THE PHOTO)

Answers

Answer:

The answer is m= 2.4r.

The equation that represents and reflects the relationship between x and y is [tex]\mathbf{y =2.4x}[/tex]

Let y represents the amount they collect, and x represents the number of raffle tickets they sell.

So, the ratio is represented as:

[tex]\mathbf{y : x =24 : 10}[/tex]

Express the ratio as fractions

[tex]\mathbf{\frac{y }{ x} =\frac{24 }{ 10}}[/tex]

Divide 24 by 10

[tex]\mathbf{\frac{y }{ x} =2.4}[/tex]

Multiply both sides by x

[tex]\mathbf{y =2.4x}[/tex]

So, the equation that represents and reflects the relationship between x and y is [tex]\mathbf{y =2.4x}[/tex]

See attachment for the graph of [tex]\mathbf{y =2.4x}[/tex]

Group of answer choices

Answers

Answer:15.5

Step-by-step explanation:

Answer:

15.5 feet

Step-by-step explanation:

To work out the perimeter of any shape, you need to add the lengths of all the sides together for the total perimeter.

4.5 + 6.4 + 4.6 = 15.5 ft

The minimum/maximum value of the function y = a(x − 2)(x − 1) occurs at x = d, what is the value of d?

Answers

Answer:

[tex]d=\frac{3}{2}=1.5[/tex]

Step-by-step explanation:

We have the function:

[tex]y=a(x-2)(x-1)[/tex]

And we want to find x=d for which the minimum/maximum value will occur.

Notice that our function is a quadratic in factored form.

Remember that the minimum/maximum value always occurs at the vertex point.

And remember that the x-coordinate of the vertex is the axis of symmetry.

Since a quadratic is always symmetrical on both sides of its axis of symmetry, a quadratic’s axis of symmetry is the average of the two roots/zeros of the quadratic.

Therefore, the value x=d such that it produces the minimum/maximum value is the average of the two roots.

Our factors are (x-2) and (x-1).

Therefore, our roots/zeros are x=1, 2.

So, the average of them are:

[tex]d=\frac{1+2}{2}=3/2=1.5[/tex]

Therefore, regardless of the value of a, the minimum/maximum value will occur at x=d=1.5.

Alternative Method:

Of course, we can also expand to confirm our answer. So:

[tex]y=a(x^2-2x-x+2)\\y=a(x^2-3x+2)\\y=ax^2-3ax+2a[/tex]

The x-coordinate of the vertex is still going to be the place where the minimum/maximum is going to occur.

And the formula for the vertex is:

[tex]x=-\frac{b}{2a}[/tex]

So, we will substitute -3a for b and a for a. This yields:

[tex]x=-\frac{-3a}{2a}=\frac{3}{2}=1.5[/tex]

Confirming our answer.
