Answer:

The top right and left are function.  The top middle is not.  

The bottom left is not a function and the bottom middle and bottom right are functions.

Step-by-step explanation:

To be a function every input can only have one output.  

The top middle is not a function because the input -7 cannot have an output of 5 and 4.

the bottom right is not a function because the input-3 cannot have the output 11 and 19.

The price of 1 hamburger is $4.6 and 1 fish sandwich is $5.2

Let 1 hamburger be x

Let 1 fish sandwich be y

Thus, we have:

3x + 2y= 24.20...... eq 1

4x + y= 23.60........ eq 2

Let's use the substitution method here:

Make y the subject formula in eq 2

y= 23.60 - 4x......... eq 3

Put the value of y into eq 1

3x + 2(23.60 - 4x) = 24.20

3x + 47.2 - 8x = 24.20

-5x + 47.2 = 24.20

Exchange values to eliminate the negative symbol

5x = 47.2- 24.20

5x= 23

x= 4.6

Put the value of x into eq 3

23.60- 4(4.6)

y= 23.60-18.4

y= $5.2

Therefore, the price of 1 hamburger is $4.6 and 1 fish sandwich is $5.2

Answer:

  (a)  -6x⁴y-2x³y² + 9x²y³ - 3xy + y⁵

Step-by-step explanation:

You want the difference of polynomials (-2x³y² + 4x²y³ - 3xy) - (6x⁴y-5x²y³ -y⁵).

The difference expression is simplified by using the distributive property and combining like terms.

  (-2x³y² + 4x²y³ - 3xy) - (6x⁴y-5x²y³ -y⁵)

  = -2x³y² + 4x²y³ - 3xy - 6x⁴y + 5x²y³ + y⁵ . . . . distribute the minus sign

  = -6x⁴y -2x³y² +(4x²y³ +5x²y³) -3xy +y⁵ . . . . . group like terms

  = -6x⁴y -2x³y² +(4 +5)x²y³ -3xy +y⁵ . . . . . . . . combine like terms

  = -6x⁴y -2x³y² +9x²y³ -3xy +y⁵

Additional comment

The terms here are written in "lexicographical" order. All terms with x are listed before any terms that do not have x. If they were listed in "standard form," terms of the same degree would be listed in lexicographical order, and terms of lower degree would be listed later. That would have the effect of interchanging the last two terms.

The difference of the value of polynomials is -6x⁴y -2x³y² +9x²y³ -3xy +y⁵

A polynomial is an expression in mathematics that consists of indeterminates (also known as variables and coefficients) and only uses the operations of addition, subtraction, multiplication, and positive-integer powers of variables. x2 4x + 7 is an illustration of a polynomial of a single indeterminate x. x3 + 2xyz2 yz + 1 is an illustration with three variables.

Numerous branches of mathematics and science make use of polynomials. For example, they are used to define polynomial functions, which appear in contexts ranging from basic chemistry and physics to economics and social science, and they are used to approximate other functions in calculus and numerical analysis.

Polynomial equations are used to encode a wide range of problems, from simple word problems to complex scientific problems.

Lets simply the polynomials

⇒ (-2x³y² + 4x²y³ - 3xy) - (6x⁴y-5x²y³ -y⁵)

= -2x³y² + 4x²y³ - 3xy - 6x⁴y + 5x²y³ + y⁵

= -6x⁴y -2x³y² +(4x²y³ +5x²y³) -3xy +y⁵

= -6x⁴y -2x³y² +(4 +5)x²y³ -3xy +y⁵

= -6x⁴y -2x³y² +9x²y³ -3xy +y⁵

Based on the fact that there are 52 cards in the standard deck and you are dealt a 7 card hand, the number of possible hands containing 3 clubs and 4 diamonds is 204,490.

The possibility of selecting a hand with 3 clubs and 4 diamonds is 0.001529.

The number of possible hands can be found as the combination of picking 3 clubs from 13 club cards and 4 diamonds from 13 diamonds card.

This gives us:

= C (13, 3) x C (13,4)

=(13! /(3! x (13 - 3 )!) x (13! / (4! x (13 - 4)!)

= 204,490 hands

The possibility of selecting a hand with 3 clubs and 4 diamonds is:
= Number of possible hands with 3 clubs and 4 diamonds / Number f possible hands from 52 card deck

Using a point, (24, 150) on the proportional graph, the constant of proportional, k = y/x = 6.25.

A proportional graph represents a proportional relationship between two variables, x and y. Variable y is dependent on variable x. x is the independent variable, and y is the dependent variable.

A proportional graph passes through the origin (0, 0). A proportional graph has a constant of proportionality, k, which is the same for every point on the graph, k = y/x. That is k remains the same, irrespective of the points on the line you chose to pick.

The graph in the image above is a proportional graph as it passes through the origin (0, 0).

To find the constant of proportional, k, any point on the line can be used.

For example, using point (12, 75) we have:

Constant of proportional, k = y/x = 75/12

Constant of proportional, k = 6.25

Also, we can also use the point, (24, 150):

Constant of proportional, k = y/x = 150/24

Constant of proportional, k = 6.25

In conclusion, using a point, (24, 150) on the proportional graph, the constant of proportional, k = y/x = 6.25.

Answer:

c = 8.75b

Step-by-step explanation:

Since each box costs the same,

The cost of one box = Total cost of 23 boxes ÷ 23

= 201.25 / 23 = 8.75

For b boxes, the total cost would be $8.75b

This should be equal to c which is the variable used to represent the total cost

So the equation is

c = 8.75b
