In a polynomial equation, the sum of the multiplicities of the roots always add up to.. the degree of the polynomial. the leading coefficient of the polynomial. the constant coefficient of the polynomial the sum of the coefficients of the polynomial.

Answers

Answer 1

Answer:

the degree of the polynomial

Step-by-step explanation:

Given

Polynomial equation

Required

What does the sum of the multiplicities add up to

To answer this question, I'll make use of the following polynomial.

[tex]p(x) = x^3 - 7x^2 + 15x - 9[/tex]

When factorized, the polynomial is:

[tex]p(x) = (x - 1)(x - 3)(x-3)[/tex]

[tex]p(x) = (x - 1)(x - 3)^2[/tex]

x-1 can be expressed as [tex](x - 1)^1[/tex]

So, we have:

[tex]p(x) = (x - 1)^1(x - 3)^2[/tex]

The sum of multiplicity (M) of the equation is 3.

This is so because

[tex]x - 1[/tex] occurred one time in [tex]p(x) = (x - 1)(x - 3)^2[/tex]

[tex]x - 3[/tex] occurred two times in [tex]p(x) = (x - 1)(x - 3)^2[/tex]

[tex]Sum= 1 + 2[/tex]

[tex]Sum= 3[/tex]

The degree of [tex]p(x) = x^3 - 7x^2 + 15x - 9[/tex] or [tex]p(x) = (x - 1)^1(x - 3)^2[/tex] is 3.

This implies that:

[tex]Sum = Degree = 3[/tex]

Hence: Option (a) answers the question

please say the right answer

Answers

Given:

The expression is

[tex]-9xy^2z[/tex]

To find:

The coefficient of x in the given expression.

Solution:

Coefficient of a variable is the product of a number and other variables multiplying the variable in an algebraic expression.

In the given expression the number and variables other than x are -9, y² and z.

So, coefficient of x is

[tex]-9\times y^2\times z=-9y^2z[/tex]

Therefore, the correct option is (d).

A line with a negative slope intersects a horizontal line 3 units above the x-axis. Select each point that can not be the intersection of the two lines.

Answers

Step-by-step explanation:

Since both lines intersect each other 3 units above the x-axis, the y-value of the point of intersection must be 3.

Looking at the options, (-3, 5), (3, -2) and (0, -3) are all invalid points.

The points that can not be the intersection points are:

(-3, 5), (3, -2), and (0, -3)

Options B, C, and D are the correct answer.

What is an equation of a line?

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

A line with a negative slope intersects a horizontal line 3 units above the x-axis.

This means,

The y-coordinate will be 3.

The y-intercept is y = 3.

The points of intersection will have the following form,

= (x, 3)

Thus,

(-3, 5), (3, -2), and (0, -3) can not be the intersection points.

How do i graph 2x + 3y = 9

Answers

1) Find the y - intercept
you can do this by finding the value for y:

2x+3y=9 —-> move 2x to the other side

3y = -2x + 9 —> then divide both sides by 3

y = -⅔x + 3 <— this is your y-intercept

to graph this, start from the point (0,0)
your first point will be the constant which in this case is number 3

so plot this 3 on your y- axis on your grid

from there, your term in the equation which in this case is -⅔x

from your first point which is (0,3) you either:

go up two times, go left three times

or

go down two times, go right three times

Given f(x) = 2x + 2, solve for x when f(x) = -4

Therefore c = -30

Hope it will help :)

Answer:

c is equal to negative thirty.

Step-by-step explanation:

You can find out what c is by subtracting 13 from both sides of the equation:

c + 13 = -17

c + 13 - 13 = -17 - 13

c + 0 = -30

c = -30

Show that the two shorter sides in triangle A have the same length as the two shorter sides in triangle B

Answers

Answer:

Step-by-step explanation:

a). Let the unknown side of triangle A = x cm

And unknown side of triangle B = y cm

By applying Pythagoras theorem in triangle A,

13² = 12² + x²

x² = 169 - 144

x² = 25 ⇒ x = 5 cm

By applying Pythagoras theorem in triangle B,

y² = 5² + 12²

y² = 25 + 144

y = √169

y = 13 cm

Therefore, smaller sides of these triangles measure 5 cm and 12 cm and they are same in measure.

b). Since, corresponding sides of both the triangles are congruent,

By SSS property of congruence, both the triangles will be congruent.

5. First choice.

Step-by-step explanation:

First Screenshot

Solve the equation.

[tex] {x}^{2} - 9 = 0[/tex]

Use the difference of two squares formula.

[tex] {x}^{2} - {y}^{2} = (x + y)(x - y)[/tex]

[tex](x + 3)(x - 3) = 0 \\ x = 3, - 3[/tex]

Second Screenshot

A linear relationship already says it all. Find the graph that is NOT a curve. The only image that is not a curve and the graph straight forwards is the Image C aka A choice.

Third Screenshot

A nonlinear function is a function that does not have a straight line graph. All linear functions are linear, except for Quadratic and up. Every polynomial function with the degree greater than one wont be a linear.

Fourth Screenshot

[tex]y = x + 3[/tex]

If we change the constant from 3 to 5 then we would get

[tex]y = x + 5[/tex]

The graph would shift up 2 units.

Last Screenshot

The second and third graph both are function. We can tell by doing a line test. Simply draw a vertical line first. Then we check if the line intercepts the graph more than a point or not.

If the line intercepts more than a point then it is not a function.

If the line intercepts only a point then it is a function.

Step-by-step explanation:

The area (A) of Δ XYZ is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height ), that is

A = [tex]\frac{1}{2}[/tex] × XY × YZ

Calculate YZ using the tangent ratio in the right triangle

tan40° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{YZ}{XY}[/tex] = [tex]\frac{x}{11}[/tex] ( multiply both sides by 11 )

11 × tan40° = x , that is

YZ ≈ 9.23 cm

Thus
