What is an expression?

A mathematical expression is a phrase containing a minimum of two numbers or variables and a minimum of one mathematical operation. It is possible to multiply, divide, add, or subtract in math. An expression has the following structure: (Mathematical Operator, Number/Variable, Expression)

The order of operations is a rule that specifies the right procedure to follow when evaluating a mathematical equation. Using the acronym PEMDAS, we can memorize this order: parentheses, exponents, multiplication, and division (left to right), addition and subtraction (from left to right).

The cost of a swim club membership for a year is $170. The price consists of 12 monthly payments of $20 and a $20 registration fee. From equation, the mth payment is $12.5 per month.

Finding the value m of each monthly payment can be done using the equation 12m+20=170.

To find the amount(m), solve the equation 12m+20=170.

12m=150

M = 150/12

M= $12.5

Consequently, each monthly payment will cost 12.5 in total.

The zeros of the function R(x) will be 0 , 4 , -4 , -5.

The equation given to us is

[tex]x^{4}[/tex] + 5[tex]x^{3}[/tex] - 16[tex]x^{2}[/tex] - 80x = 0

Take x common

x( [tex]x^{3}[/tex] + 5[tex]x^{2}[/tex] - 16x - 80 ) = 0

from here we get one factor of x as 0.

Now

[tex]x^{3}[/tex] + 5[tex]x^{2}[/tex] - 16x - 80 = 0

It is given that  x + 5) is a factor of this equation. so we will divide the equation by (x + 5).

After dividing it by (x + 5) we get [tex]x^{2}[/tex] - 16

Which can be written as [tex]x^{2}[/tex] - [tex]4^{2}[/tex] = (x + 4) (x - 4)

From here we get rest of the two roots of the equation.

Answer:

D)  0, 4, -4, -5

Step-by-step explanation:

Given polynomial:

[tex]R(x)=x^4+5x^3-16x^2-80x[/tex]

Given (x + 5) is a factor of R(x), use long division to find the other factor:

[tex]\large \begin{array}{r}x^3-16x\phantom{)}\\x+5{\overline{\smash{\big)}\,x^4+5x^3-16x^2-80x\phantom{)}}}\\{-~\phantom{(}\underline{(x^4+5x^3)\phantom{-b))))))))))))}}\\-16x^2-80x\phantom{)}\\-~\phantom{()}\underline{(-16x^2-80x)\phantom{}}\\0\phantom{)}\\\end{array}[/tex]

Therefore:

[tex]R(x)=(x^3-16x)(x+5)[/tex]

Factor out x from the first factor:

[tex]R(x)=x(x^2-16)(x+5)[/tex]

Apply the Difference of Two Square Formula: a²-b²=(a-b)(a+b)

[tex]\begin{aligned}\implies x^2-16&=x^2-4^2\\&=(x-4)(x+4)\end{aligned}[/tex]

Therefore:

[tex]R(x)=x(x-4)(x+4)(x+5)[/tex]

Zero Product Property

If a ⋅ b = 0 then either a = 0 or b = 0 (or both).

To find the zeros of the function, apply the zero-product property by setting each factor equal to zero and solving for x:

[tex]\implies x=0[/tex]

[tex]\implies x-4=0 \implies x=4[/tex]

[tex]\implies x+4=0 \implies x=-4[/tex]

[tex]\implies x+5=0 \implies x=-5[/tex]

Therefore, the zeros of the function R(x) are:

Step-by-step explanation:

You could think of ratios as fractions :

Whatever we do to the top we must do to the bottom to keep it equivalent .

If we multiply the first thing by something we must do the multiply by the same number to the second.

2 × m = 8

m = 4

3 × m = ?

m = 4

3 × 4 = 12

? = 12

So the number that makes the ratio equivalent is 12

By using angles properties (sum of interior angles of a triangle and so) we will see that the measure of angle x is 120°.

Let's define C as the angle inside the triangle that is adjacent to angle x.

We can see that these two are supplementary angles, then we know that:

C + x = 180°.

We also can see that C is an interior angle of a triangle, and remember that the sum of all interior angles of a triangle is equal to 180°, then we can write

68° + 52° + C = 180°

With that equation, we can find the value of C.

C = 180° - 52° - 68° = 60°

Then.

x + C = 180°

x + 60° = 180°

x = 180° - 60° = 120°

That is the measure of angle x.

The slope of the line that goes through these two points is -19/13.

Given points:

(–6, −3), (–19, 16)

slope:

Slope is the steepness of a line as it moves from LEFT to RIGHT. Slope is the ratio of the rise, the vertical change, to the run, the horizontal change of a line. The slope of a line is always constant (it never changes) no matter what 2 points on the line you choose.

slope m = y2-y1 / x2-x1

= 16-(-3) / -19-(-6)

= 16+3/-19+6

= 19/-13
