what relationship is used to find the slope of a line?

Answer:

6x³ - 4x² + 4x

Step-by-step explanation:

The additive inverse is the value added to make the expression equal to zero.

Given

- 6x³ + 4x² - 4x , then the additive inverse is

- ( - 6x³ + 4x² - 4x)

= 6x³ - 4x² + 4x

The additive inverse of the polynomial is 6x³ - 4x² + 4x.

Given: Polynomial

-6x³ + 4x² - 4x

Additive inverse of the polynomial is the polynomial when added to the original polynomial gives the sum zero.

Let, the additive inverse of the given polynomial be P.

⇒ P + -6x³ + 4x² - 4x = 0

⇒ P = 6x³ - 4x² + 4x

Therefore, the additive inverse of the given polynomial is 6x³ - 4x² + 4x.

The system of linear inequalities which is represented by the  graph is:

        y>x-2 and    y<x+1

The first inequality--

It is a dotted line which passes through (-1,0) and (0,1) and the shaded region is below the line.

first we find the equation of line:

The equation of a line passing through (a,b) and (c,d) is given by:

[tex]y-b=\dfrac{d-b}{c-a}\times (x-a)[/tex]

Hence,

(a,b)=(-1,0) and (c,d)=(0,1)

Hence, the equation of line is:

[tex]y-0=\dfrac{1-0}{0-(-1)}\times (x-(-1))\\\\i.e.\\\\y=\dfrac{1}{1}\times (x+1)\\\\i.e.\\\\y=x+1[/tex]

Also, the inequality is strict since the line is dotted.

Hence, the inequality is given by: y<x+1

The second inequality --

is a dotted line which passes through (0,-2) and (2,0)

and the shaded region is above the line.

The equation of line is given by:

  y=x-2

and the inequality is strict.

Hence, the inequality is given by:

        y>x-2

I believe the answer is 286 since the equation is 250(1.07) t

this tells me that 250= original size and 1.07= growth of the bacteria and t for time or hour in this case

250x(1.07) 2

267.5x(1.07)

286.225 = 286

Final answer:

The dealer's cost for the car is $15,851.65 and the sticker price is $20,636.

Explanation:

To find the sticker price and dealer's cost for the car, we need to calculate the prices of the base price, options, and destination charges.

First, calculate the dealer's cost for the base price by multiplying 85% of the base price: $18,649 x 0.85 = $15,851.65.

Next, calculate the dealer's cost for the options by multiplying 70% of each option cost and summing them up: $453 x 0.70 + $612 x 0.70 + $386 x 0.70 + $290 x 0.70 = $845.20.

Finally, calculate the sticker price by adding the base price, options, and destination charges: $18,649 + $453 + $612 + $386 + $290 + $246 = $20,636.

Therefore, the dealer's cost is $15,851.65 and the sticker price is $20,636.

Answer:

(2y-cubert(15)x)(4y^2+2cubert(15)xy+cubert(15^2)x^2)

Step-by-step explanation:

It almost look like someone possibly meant to write a perfect cube there instead of 51... but we can still factorize this... it just won't be as pretty.

The formula for factoring a difference of cubes is

u^3-v^3

=(u-v)(u^2+uv+v^2).

So the answer here is

(2y)^3-(cubert(15)x)^3

=(2y-cubert(15)x)(4y^2+2cubert(15)xy+cubert(15^2)x^2)

cubert means cube root of

1. The given absolute value inequality is:

[tex] |x| \: > \: 5[/tex]

This implies that;

[tex] - x \: > \: 5 \: or \: x \: > \: 5[/tex]

We the first inequality by -1 and reverse the sign to get:

[tex]x \: < - \: 5 \: or \: x \: > \: 5[/tex]

The correct answer is

C. { x|x < -5 or x > 5}

2. The given inequality is:

[tex] |4x - 8| \: < \: 12[/tex]

This implies that,

[tex] - (4x - 8) \: < \: 12 \: or \: (4x - 8) \: < \: 12[/tex]

Divide through the first inequality by -1 and reverse the sign

[tex]4x - 8\: > \: - 12 \: or \: 4x - 8\: < \: 12[/tex]

Group similar terms:

[tex]4x \: > \: - 12 + 8 \: or \: 4x \: < \: 12 + 8[/tex]

Simplify:

[tex]4x \: > \: - 4\: or \: 4x \: < \: 20[/tex]

Divide both sides by 4

The graph is attached.

To find the graph that shows the solution to the system of linear inequalities below, we need to find the axis intercepts and consider the given conditions for both inequalities.

So, solving we have:

First inequality: Blue line and area.

[tex]y\leq -3x+2[/tex]

Finding the x-axis intercept, making "y" equal to 0.

[tex]y=-3x+2[/tex]

[tex]0=-3x+2\\\\3x=2\\\\x=\frac{2}{3}=0.66[/tex]

So, the x-axis intercept is located at the point (0.66,0)

Finding the y-axis intercept, making "x" equal to 0.

[tex]y=-3x+2[/tex]

[tex]y=-3*0+2=2[/tex]

So, the y-axis intercept is located at the point (0,2)

Also, we can see that since the coefficient of the linear term is negative (-3) the line is decreasing (line with negative slope).

Now, that we already know the axis intercepts, we need to remember that the inequality is given by the following expression:

[tex]y\leq -3x+2[/tex]

The less or equal inequality symbol means that the solution region of the inequality is under the function.

Second inequality: Red line and area.

[tex]y>2x-3[/tex]

Finding the x-axis intercept, making "y" equal to 0.

[tex]y=2x-3+2[/tex]

[tex]0=2x-3\\\\2x=3\\\\x=\frac{3}{2}=1.5[/tex]

So, the x-axis intercept is located at the point (1.5,0)

Finding the y-axis intercept, making "x" equal to 0.

[tex]y=2x-3[/tex]

[tex]y=2*0-3=-3[/tex]

So, the y-axis intercept is located at the point (0,-3).

Also, we can see that since the coefficient of the linear term is positive (-3) the line is increasing (line with positive slope).

Now, that we already know the axis intercepts, we need to remember that the inequality is given by the following expression:

[tex]y>2x-3[/tex]

The greater inequality symbol means that the solution region of the inequality is above the function.

Hence, since we have a system of linear inequalities, the solution to the whole system is located between the solution region of the given inequalities.

The graph is attached, the solution to the system of linear inequalities is represented by the shaded area (light purple area).

Final answer:

Strategic voting leads to the Pepsi candidate winning the election for Soft Drink commissioner, despite the strong preference for Coca-Cola among the voting population.

Explanation:

The Pepsi candidate wins in a landslide in the election for Soft Drink commissioner, despite there being a strong preference for Coca-Cola among the voting population because of the concept of strategic voting. Strategic voting occurs when voters strategically choose a candidate who they believe has a better chance of winning, rather than their preferred choice. In this scenario, it is possible that the supporters of the Coca-Cola party split their votes among the four candidates, while the supporters of the Pepsi candidate remained united, resulting in the Pepsi candidate winning by a large margin.

Option D. (0, 2)

Step-by-step explanation:

we have

[tex]f(x)=2(3)^{x}[/tex]

This is a exponential function of the form

[tex]y=a(b)^{x}[/tex]

where

a is the initial value

b is the base

r is the rate of change

In this problem

a=2 ---> the initial value ( value of the function when the value of x is equal to zero)

b=3

b=1+r ----> 3=1+r ----> r=2 ---> r=200%

Remember that

The initial value of the function is equal to the y-intercept

The initial value is the point (0,2)

therefore

The y-intercept is the point (0,2)

the slope intercept form is y=mx+b

since the line intersects at (0,3) b= 3

since the slope is 0 m= 0

so the equation would be y=0x+3 or y=3

Answer:

y=3

Step-by-step explanation:

Hi there!

We are given that a line contains the point (0, 3), and has the slope 0

We want to find the equation of this line, in slope-intercept form.

Slope-intercept form is given as y=mx+b, where m is the slope and b is the y intercept

The y intercept is the point that intersects the y axis; at this point, the value of x is 0

The point (0, 3) we were given is actually the y intercept of this line (the value of x at this point is 0!)

We can therefore, plug it into the formula.

We can just plug in the y value as b into the equation.

Here's the equation so far:

y=mx+3

Now we need to find m.

As the the slope of the line is 0, it means that if we plug 0 in as m, then we can find the equation of the line.

So substitute 0 as m

y=0x+3

This can also be written as y=3

Hope this helps!

The system of equations y = 1/4x + 2 and 3y = -3/4x - 6 represents two distinct parallel lines with the same slope but different y-intercepts, thus the system has no solution.

Explanation:

To find the solution to the system of equations y = 1/4x + 2 and 3y = -3/4x - 6, we need to check if they have a common solution, indicating the point where they intersect, or if they are parallel, which would mean they have no solution, or if they are the same line, which would translate into infinitely many solutions.

First, simplify the second equation by dividing every term by 3, which gives y = -1/4x - 2. Now we can see that the coefficients of x and the constant terms in both equations are multiples of one another but with opposite signs, which means the lines are parallel and have the same slope but different y-intercepts. Therefore, these two equations represent two distinct parallel lines that never intersect.

The correct answer is that there is no solution to this system of equations because the lines are parallel and will never meet.
