We get the inequality as:

There is no image to refer. So, here answering in general way.

Given,

The boundary line, y = -3x - 4

We can have 4 cases:

1) A dashed line and the shaded part is above the line.

y > -3x - 4

2) A dashed line and the shaded part is below the line

y < -3x - 4

Here we have dashed lines because the values of the line are not solutions for the inequality.

3) A solid line and the shaded part is above the line.

y ≥  -3x - 4

4) A solid line and the shaded part is below the line.

y ≤  -3x - 4

Here we have solid lines because the values in the line itself are solutions.

Answer:

it will be 100 dollar because it spend 50$ on each

The selling price of the bicycle in discuss upon addition of the mark-up which is 33.3% as described in the task content is; $131.63.

The wholesale cost price of the bicycle in discuss is $98.75 as described in the task content while the markup for the bicycle is as given in the task content.

On this note, it follows that the selling price of the bicycle is the sum of its cost price and it's mark-up. Hence, we have;

Selling price = $98.75 + (33.3% of $98.75)

= $98.75 + (0.333 × $98.75)

= 98.75 + 32.88

= $131.63.

Ultimately, selling price of the bicycle in discuss upon addition of the mark-up which is 33.3% as described in the task content is; $131.63.

Answer:

x^3 + 5

Explanation:

The residual value with an actual value of 10 and a predicted value of 14 will be 4. Then the correct option is D.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

We know that the difference between the predicted value and to actual value is known as the residual value.

Residual value = Predicted value - Actual value

If the observed (actual) y value is 10, and the predicted value is 14. Then the residual value will be

Residual value = 14 - 10

Residual value = 4

The residual value will be 4. Then the correct option is D.

Answer:

Step-by-step explanation:

Given functions h(x)=x²+1 and k(x)=x-2, you want the values of (h+k)(2), (h-k)(3) and 3h(2)+2k(3).

The value of a function f(x) is found by substituting the argument value for x in the function definition, then doing the arithmetic.

The value of a sum or difference of functions is the sum or difference of the values of those functions for the given argument.

  (h+k)(2) = h(2) +k(2) = (2²+1) +(2 -2) = 5 +0 = 5

  (h-k)(3) = h(3) -k(3) = (3² +1) -(3 -2) = 10 -1 = 9

   3h(2) +2k(3) = 3(2² +1) +2(3 -2) = 3(5) +2(1) = 17

The weighted average is -33.

given,(2,8)(-4.-7)and their weighted average is 3:5

Weighted average is a calculation that takes into account the varying degrees of importance of the numbers in a data set. In calculating a weighted average, each number in the data set is multiplied by a predetermined weight before the final calculation is made.

(2,8)x5=10+40

           =50

(-4,-7)x3=-12-21

            =-33

therefoe, the weighted average is -33.

The average is the sum of all individual observations divided by the number of observations. In contrast, the weighted average is observation multiplied by the weight and added to find a solution.

Given the functions f(x) = 1/x and g(x) = x⁴, the function operation ( f + g )(x) is x⁴ + 1/x.

Given the functions in the question;

To evaluate f + g, replace the function designators in f + g with the actual functions and simplify

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

( f + g )(x) = ( 1/x ) + ( x⁴ )

Remove the parenthesis

( f + g )(x) = ( 1/x ) + ( x⁴ )

( f + g )(x) = 1/x + x⁴

Reorder 1/x and  x⁴

( f + g )(x) = 1/x + x⁴

( f + g )(x) = x⁴ + 1/x

Given the functions f(x) = 1/x and g(x) = x⁴, the function operation ( f + g )(x) is x⁴ + 1/x.

0.620  is the probability that the animal Fran picks is poisonous or is a snake .

How does probability explain work?

Total animal = ( 6 + 8 + 11 + 4 ) =  29

Let,  p = Event of poisonous animal

        s = event of spider

     p U s = event of poisonous or spider

      p ∩ s = event of poisonous or spider

n(P)   =  No of poisonous = ( 6 + 11 ) = 17

n(S)    =  No of spider =   ( 8 + 4 ) = 12

n(P ∩ S)  No of poisonous spider = 11

Then ,    P [ P ] = 17/29       , P [S ] = 12/29     P [ P ∩ S ] = 11/29

   P [ poisonous or spider ]

 = P [ P ∪ S ] = P [P] + P [ S ] - P [ P ∩ S  ]

                     = 17/29  + 12/29 - 11/29

The greatest number of persons that would be invited is 51.

In order to get the greatest number of person that they would be inviting we would have this equation

100+37x ≤ 2,000

Where we have money budgeted to be 2000 dollars

cleanup fee = 100 dollars

Amount per person = 37 dollars

Then we would have

100+37x ≤ 2,000

37x ≤ 2000 - 100

37x ≤ 1900

we have to divide through by 37

37/37 = 1900 / 37

x = 51.3

Hence we would say that the greatest number of persons that would be invited is 51.

e) The first five terms of the sequence are 1, 3, 7, 13 and 21.

Recurrence formulas are expressions that generates an element of a sequence in terms of previous elements of the series. Now we proceed to calculate the first elements of each sequence:

Case A

n = 1

a(1) = 1

n = 2

a(2) = 3 · a(1)

a(2) = 3

n = 3

a(3) = 3 · a(2)

a(3) = 9

n = 4

a(4) = 3 · a(3)

a(4) = 27

n = 5

a(5) = 3 · a(4)

a(5) = 81

The first five terms of the sequence are 1, 3, 9, 27 and 81.

Case B

n = 1

b(1) = 1

n = 2

b(2) = - 2 + b(1)

b(2) = - 1

n = 3

b(3) = - 2 + b(2)

b(3) = - 3

n = 4

b(4) = - 2 + b(3)

b(4) = - 5

n = 5

b(5) = - 2 + b(4)

b(5) = - 7

The first five terms of the sequence are 1, - 1, - 3, - 5 and - 7.

Case C

n = 1

c(1) = 1

n = 2

c(2) = 2 · c(1) + 1

c(3) = 7

n = 4

c(4) = 2 · c(3) + 1

c(4) = 15

n = 5

c(5) = 2 · c(4) + 1

c(5) = 31

The first five terms of the sequence are 1, 3, 7, 15 and 31.

Case D

n = 1

d(1) = 1

n = 2

d(2) = [d(1)]² + 1

d(2) = 2

n = 3

d(3) = [d(2)]² + 1

d(3) = 5

n = 4

d(4) = [d(3)]² + 1

d(4) = 26

n = 5

d(5) = [d(4)]² + 1

d(5) = 677

The first five terms of the sequence are 1, 2, 5, 26 and 677.

Case E
