The property of equality applied to solve the equation is division property of Equality.

Property of equality says that by performing any mathematical operation, of both sides of an expression does not change the original value of the equation.

The equation given in the problem is,

[tex]0.36 x = -1. 8[/tex]

This equation is solved further by dividing both side of the expression with decimal number 0.36 as,

[tex]\dfrac{0.36}{0.36}x = -\dfrac{1. 8}{0.36}\\x=-5[/tex]

Here, the division operation is performed both sides of the equation to solve the equation. This does not change the original value of the equation and gives the value of unknown number.

Thus, the property of equality applied to solve the equation is division property of Equality.

Answer:

f(g(x)) = g(f(x)) = x

which is the same as

Answer:

86 adults and 270 children

Step-by-step explanation:

Let x = # of adult tickets;

then the number of children tickets is (356-x).

Write the total money equation (revenue equation)

   [tex]1.75*(356-x) + 2.25x = 666[/tex]  dollars.

From the equation

  [tex]x = \frac{666-1.75*356}{2.25-1.75} = 86[/tex]

ANSWER.  86 adults and 356-86 = 270 children.

Answer:

His total run is approximately 3.37 miles.

Step-by-step explanation:

Let F represents his starting point, C represents his position from where he went to east direction and H represents his position from where he went to left towards Florida Avenue.

Thus, according to the question,

FC = 0.75 miles,

CH = 1.2 miles,

By making the diagram,

∠FCH = 90°,

By Pythagoras theorem:

Hence, the total distance he covered = FC + CH + FH

= 0.75 + 1.2 + √2.0025

= 3.36509716981

≈ 3.37 miles.

Answer:

No

Step-by-step explanation:

Because if 8i is a zero then -8i is also a zero. That means you now have four zeros, so the function is at least a fourth degree (quartic) function.

It is not possible to write a polynomial of degree 3 with zeros 5, 3 and 8i.

A polynomial’s degree is the highest or the greatest power of a variable in a polynomial equation.

The degree of a polynomial is equal to the real zeros of the polynomial. Real zeros of the polynomial are 5 and 3 only. 8i is a complex number. Thus degree of the polynomial is 2.

Answer:

"y" would be 120 degrees.  The image is a parallelogram.

Step-by-step explanation:

Using the vertex of the quadratic function, it is found that his maximum profit is of $75 when he charges $15 for a key-chain.

A quadratic equation is modeled by:

[tex]y = ax^2 + bx + c[/tex]

The vertex is given by:

[tex](x_v, y_v)[/tex]

In which:

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

[tex]y_v = -\frac{b^2 - 4ac}{4a}[/tex]

Considering the coefficient a, we have that:

In this problem, the function is:

[tex]f(x) = (x - 10)(60 - 3x)[/tex]

In standard format, it is given by:

[tex]f(x) = -3x^2 + 90x - 600[/tex]

Which means that it's coefficients are a = -3, b = 90, c = -600.

Hence:

[tex]x_v = -\frac{90}{2(-3)} = 15[/tex]

[tex]y_v = -\frac{90^2 - 4(-3)(-600)}{4(-3)} = 75[/tex]

Hence, his maximum profit is of $75 when he charges $15 for a key-chain.
