Answer:

W = -57.6         PS: I'm in 8th grade.

Step-by-step explanation:

W/6 + 7.2 = -2.4   Step 1: Use Inverse operations (subtract 7.2 on both sides)

W/6 = -2.4 - 7.2    Step 2: Combine Like terms (-2.4 - 7.2)

W/6 = -9.6            Step 3: Use Inverse Operations (multiply by 6 on both sides)

W = -9.6 x 6         Step 4: Simplify

Using the Factor Theorem, the quadratic functions are given as follows:

The Factor Theorem states that a polynomial function with roots [tex]x_1, x_2, \codts, x_n[/tex] is given by:

[tex]f(x) = a(x - x_1)(x - x_2) \cdots (x - x_n)[/tex]

In which a is the leading coefficient.

For this problem, the roots are given as follows:

[tex]x_1 = -3, x_2 = 8[/tex]

Hence:

f(x) = a(x + 3)(x - 8)

f(x) = a(x² - 5x - 24).

It opens upward with a positive leading coefficient, that is, a > 0, hence one example is a = 1 as follows:

f(x) = x² - 5x - 24.

It opens downward with a negative leading coefficient, that is, a < 0, hence one example is a = -1 as follows:

f(x) = -x² + 5x + 24.

By solving a system of equations we can see that the quadratic equation is:

y = x^2 + 3x + 10

A general quadratic equation is given by:

y = a*x^2 + b*x + c

We want this quadratic equation to pase through the points (-2, 8), (1, 14), and (0, 10).

using the last point, we know that when x = 0, we must have y = 10, then:

10  = a*0^2 + b*0 + c

10 = c

So our quadratic equation is:

y = a*x^2 + b*x + 10

Now we use the other two points to write a system of equations:

8 = a*(-2)^2 + b*(-2) + 10

14 = a*(1)^2 + b*1 + 10

If we simplify these, we get:

-2 = 4*a - 2b

4 = a + b

Isolating a in the second equation we get:

a = 4 - b

Now we replace that in the other equation:

-2 = 4*(4 - b) - 2b

-2 = 16 - 4b -2b

-2 - 16 = -6b

-18/-6 = b = 3

Now that we know the value of b, we replace it in the equation for a:

a = 4 - b = 4 - 3 = 1

Then the quadratic equation is:

y = x^2 + 3x + 10

With the help of linear equtions it can be concluded that we downloaded 54 songs in which 28 songs were free and 26 songs were paid.

A linear equation is an algebraic equation in which each term has an exponent of one and when graphed produces a straight line. That's why it is considered a 'linear equation.'

Let a represent paid downloaded songs.

Total cost of songs downloaded = a x cost of each additional download.

a x $0.59 = $0.59a

The overall cost of downloaded songs is $15.34.

$15.34 =   $0.59a

Divide both sides of the equation by  $0.59.

a = 26 songs

We downloaded 26 paid songs.

Total songs downloaded = total free songs + total paid songs

Total songs downloaded = 26 + 28 = 54 songs

The property that justifies the following statement, 5(3 x+1)=15 x+5 is the distributive property.

Distributive property can be described as one of the properties of multiplication which states that if we multiply two or more values that are added together with a number then the result will be the same even if we multiply each value separately with that number and then add them together. This can be given as:

x(y + z) = xy + xz

Therefore, as 5 x 3 = 15 and 5 x 1 =5, we can write the equation 5(3x+1) as 15x + 5 as the result will be the same in both circumstances.

The distributive property not only justifies the equations when two or more values are added but also justifies the equations in which they are subtracted which can be given as:

x(y-z) = xy - xz

The canonical equation of a parabola is given by

(y - k)² = 4p(x - h)

The parabola is a quadratic function, it is composed of a vertex, or inflection point, a focus and a directrix.

Since the vertex and the focal axis are on the same axis, we analyze that:

v (0, 0)

f (6, 0) the focus is on the right so the parabola is of the form X = Y².

(y - 0)² = 4p(x - 0)

f = (0 + p, 0)

b and 81° are same- side interior angles and sum to 180° , that is

b + 81 = 180 ( subtract 81 from both sides )

b = 99

Answer:

12°

Step-by-step explanation:

The angles of the shape should all add to 360°.

We divide this by 30, because the shape has 30 angles.

360° ÷ 30 = 12°.

This is the measure of each angle, and also the degree of rotation. The shape will look like the original figure each time it is rotated 12°.
