The remainder when the polynomial p(x) = 2x³ + 4x² - 2x + 12 is divided by x + 3 is -6.

A polynomial is an expression consisting of the operations of addition, subtraction, multiplication of variables.

The remainder theorem states that for a polynomial, f(x) divided by a linear polynomial , x - a, the remainder is equal to f(a).

Given the polynomial; p(x) = 2x³ + 4x² - 2x + 12, since it is divided by x + 3, hence:

x + 3 = 0

x = -3

p(-3) = 2(-3)³ + 4(-3)² - 2(-3) + 12 = -6

Hence the remainder when the polynomial p(x) = 2x³ + 4x² - 2x + 12 is divided by x + 3 is -6.

Answer:

y > 1/2x - 1

First, draw the dashed line y = 1/2x - 1 (slope intercept ; y = mx + b).

Start at -1 on the y-axis, and continue going 2 units to the right, and 1 unit up for the right side of the graph.

Then starting at -1 on the y-axis, continue going 2 units to the left, and 1 unit down for the left side of the graph.

Explanation:

Convert standard form (Ax + By = C) by isolating y from the rest of the equation.

Ax + By = C → y = -Ax/B + C/B → y = mx + b.

Given a standard form equation in inequality form,

x - 2y < 2.

Set it to slope-intercept as an inequality to find the slope and y-intercept.

When negating (making opposite) a variable, you flip the inequality.

x - 2y < 2 → x - 2y - x < 2 - x → -2y < -x + 2 → 2y > x - 2 → y > 1/2x - 1.

Answer:

  19) x = number of people; y = cost

  20) (people, cost) = (15, 120) and (25, 200)

  21) the rate of change is $8 per person

  22) y = 8x

  23) $320

Step-by-step explanation:

19) The problem statement tells you x is the number of people and y is the cost.

__

20) Writing the pairs (people, cost), we have ...

  (15, 120) and (25, 200)

__

21) The rate of change can be found from the slope formula:

  m = (y2 -y1)/(x2 -x1)

  m = (200 -120)/(25 -15) = 80/10 = 8

The rate of change is $8 per person.

__

22) In point-slope form, the rule is ...

  y -y1 = m(x -x1)

  y -120 = 8(x -15)

  y = 8x -120 +120

  y = 8x

__

23) For x=40, y = 8(40) = 320

A party for 40 people will cost $320.

Answer:x =24

Step-by-step explanation: If we reverse that we will get x= 32x3/4 which is 24

Answer:

x = -24

Step-by-step explanation:

(-4/3)x -6 =26

Add 6 to both sides:

(-4/3)x = 32

(-4/3) = -1.33333333

divide both sides by -1.33333333

x = -24

Substitute:

(-4/3)(-24) -6 =26

32 - 6 = 26

26 = 26

x = -24

Answer:

Step-by-step explanation:

Using the area model and standard algorithm, we have:

                332   (tenths)

          ×       21  

                332

             664    

             6972   tenths = 697.2

              30      +      3      tenths

     1       300           32         332

    20     600           64         664

33.2 × 21 =    30     ×    1      =        30    

The equation of line is given by y = ( 1/6 )x + 5 , where the slope of the line m is = 1/6

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

y = ( 1/6 )x + 5   be equation (1)

Now , it is of the form y = mx + b where m is the slope and b is the y-intercept

So , the slope of the line A is given by

Slope m = ( 1/6 )

Now , the line is plotted in the graph below

Hence , the equation of line is y = ( 1/6 )x + 5

Answer:

$13,400

Step-by-step explanation:

Given the following data;

Tuition and book per year = $5,500

Transportation per month = $100

In 2 years;

Total tuition and book = $5,500 * 2 = $11,000

Total tuition and book cost = $11,000

Transportation;

There are 12 months in a year, in 2 years = 12 * 2 = 24 months.

Thus, total on transportation = $100 * 24 = $2,400

Total transportation cost = $2,400

[tex] Overall \; cost = Total \; tuition \; and \; book \; cost + Total \; transportation \; cost[/tex]

Substituting into the above equation, we have;

Overall cost = $11,000 + $2,400

Overall cost = $13,400.

Hence, Lakita's education will cost her $13,400 in total.
