How many 1-1 functions from a set with five elements to a set with 4 elements?

Answer:

Options A, C and D.

Step-by-step explanation:

It is given that, we need 1 tablespoon of butter for every 6 eggs to make a quiche.

Ratio that compares these two quantities [tex]=\dfrac{6\text{ eggs}}{1\text{ tablespoons} }[/tex]

We need to find the ratios which are equivalent to this ratio.

[tex]\dfrac{6\text{ eggs}}{1\text{ tablespoons} }\times \dfrac{2}{2}=\dfrac{12\text{ eggs}}{2\text{ tablespoons} }[/tex]

[tex]\dfrac{6\text{ eggs}}{1\text{ tablespoons} }\times \dfrac{3}{3}=\dfrac{18\text{ eggs}}{3\text{ tablespoons} }\neq \dfrac{15\text{ eggs}}{3\text{ tablespoons} }[/tex]

[tex]\dfrac{6\text{ eggs}}{1\text{ tablespoons} }\times \dfrac{4}{4}=\dfrac{24\text{ eggs}}{4\text{ tablespoons} }[/tex]

[tex]\dfrac{6\text{ eggs}}{1\text{ tablespoons} }\times \dfrac{1.5}{1.5}=\dfrac{9\text{ eggs}}{1.5\text{ tablespoons} }[/tex]

Therefore, the correct options are A, C and D.

Answer:

Answer: -6.5

Step-by-step explanation:

To find the number between them,find their average or mean .

-6 + -7 = -13

-13/2 = -6.5  

The number between them is -6.5

Answer:

The missing number is:

22

Step-by-step explanation:

There are 3 numbers and one more

4 numbers and your average is 17

then:

17*4 = 68

then:

11 + 17 + 18 + a = 68

46 + a = 68

a = 68 - 46

a = 22

Check:

(22 + 11 + 17 + 18)/4 = 17

68/4 = 17

Answer:

Mark is 42. 3J = M and J + M = 56

Step-by-step explanation:

Since Mark is 3 times as old as Julie, and the sum of their ages is 56, you could divide 56 by 4 (one time because of Julie’s age, the other 3 times because of how many times Mark is older than Julie) You would get 14. That means that Julie is 14. To find Mark’s age, you would multiply 14 (Julie’s age) by 3. The answer would be 42.

Using the numbers you have :

6 to -2

-2 to 2

4 to 1

-1 to 1

This is a function.

An input can only have one output, but an output can have multiple inputs.

We can make a table with the values we are given.

6 and -2

4 and -1

2 and 2

-2 and 1

Since no x-value repeats itself, it is a function. To make a function, no x-values can be repeated.

Best of Luck!

Answer:

Property of Equality

Y= -13/7

Step-by-step explanation:

7y – 15 = –29.

Applying rule of equality which is"anything done on one side of the equal sign should be done also on the other side of the equal sign"

7y – 15 = –29.

Adding 15 to both sides

7y - 15+15= -28+15

7y= -13

Dividing throughout by 7

7y/7= -13/7

Y= -13/7

Answer:

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{x = 4}}}}}[/tex]

Step-by-step explanation:

[tex] \sf{2x + 4 = 12}[/tex]

Move 4 to right hand side and change it's sign

[tex] \dashrightarrow{ \sf{2x = 12 - 4}}[/tex]

Subtract 4 from 12

[tex] \dashrightarrow{ \sf{2x = 8}}[/tex]

Divide both sides by 2

[tex] \dashrightarrow{ \sf{ \frac{2x}{2} = \frac{8}{2} }}[/tex]

Calculate

[tex] \dashrightarrow{\sf{x = 4}}[/tex]

Hope I helped!

Best regards! :D

Answer:

[tex]x=4[/tex]

Step-by-step explanation:

[tex]2x+4=12[/tex]

To solve this equation, first we must minus out(subtract) 4 from both sides of the equation.

[tex]2x+4-4=12-4[/tex]

This equals [tex]2x=8[/tex]

Now we will make this into a fraction and divide the sides by 2.

[tex]\frac{2x}{2}[/tex] equals to [tex]\frac{8}{2}[/tex]

Now we got an answer!

[tex]x=4[/tex]

Answer:

X=7

Step-by-step explanation:

4(x+3) - 10=6 ( x-2)

multiply

4x +12 - 10 = 6x - 12

4x + 2 = 6x- 12

subtract the positive 2 to the -12

4x = 6x -14

subtract 6x to the 4x

-2x = -14

divide -2 from the -14 (neg divided by a neg = positive)

Answer:

52 square in

Step-by-step explanation:

x2 is 25 by 50

The area of the new rectangle in terms of x is  2x² - 3x + 1 sq inches.

The area of a rectangle is the product of its length and width.

The perimeter of a rectangle is the sum of the lengths of all the sides.

We know the area of a rectangle is (length×width).

Given,  A paper with a width of x inches, and a length of 2x inches.

So, The area is (x×2x) sq inches.

= 2x² sq inches.

Now, he cut off one inch of both the length and the width which is,

= (x - 1)(2x - 1) sq inches.

= 2x² - x - 2x + 1 sq inches.

= 2x² - 3x + 1 sq inches.

Answer:

a) (1, 2) not on the graph.

b) (1, -1) is on the graph.

Step-by-step explanation:

Given the equation of the line as:

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

The points given are

a) (1, 2)

To determine whether it is on the graph of the line or not.

To do so, we can do 2 things:

1. Draw the graph and plot the point on the graph to check whether it is on the graph or not.

2. To put the point in the given equation of the line, whether the equation is satisfied or not.

For method 1: Kindly refer to the attached image of the line and point plotted.

Method 2:

Let us put [tex]x=1, y=2[/tex] in the Left Hand Side (LHS) of equation.

[tex]2\times 1 - 2 - 3\\\Rightarrow -3 \neq 0 , RHS[/tex]

(1, 2) Not on the graph.

(b) (1, -1)

For method 1: Kindly refer to the attached image of the line and point plotted.

Method 2:

Let us put [tex]x=1, y=-1[/tex] in the Left Hand Side (LHS) of equation.

[tex]2\times 1 - (-1) - 3\\\Rightarrow 3-3 = 0 = RHS[/tex]

(1, -1) is on the graph.

Hey there! I think the answer is (-1,3)

Answer:

the EOQ cost function [tex]\mathbf{g(Q)= \dfrac{h}{2 \lambda Q}( Q- \sqrt{\dfrac{2 \lambda K }{2}})^2 + \sqrt{\dfrac{2 h K}{\lambda}}}[/tex]

Step-by-step explanation:

Given that:

[tex]g(Q) = \dfrac{h}{2 \lambda Q} \begin {pmatrix} Q- \sqrt{\dfrac{2 K \lambda}{h}} \end {pmatrix}^2 + \sqrt{\dfrac{2 Kh}{\lambda}}[/tex]

Total cost = Purchase Cost + Ordering Cost + Holding Cost

i.e

T = [tex]P \lambda + h \dfrac{Q}{2}+\dfrac{\lambda K}{Q}[/tex]

By differentiating with respect to Q and equating to zero, we have:

[tex]0 = 0 +\dfrac{h}{2}- \dfrac{\lambda K}{Q^2}[/tex]

[tex]Q* = \sqrt{\dfrac{2 k \lambda}{h}}[/tex]

Now;

[tex]T = P \lambda + \dfrac{h}{2Q}(Q-Q^*)^2 + hQ^*[/tex]

[tex]T = \dfrac{h}{2Q}(Q- \sqrt{\dfrac{2 \lambda K}{h}})^2 + \sqrt{2 hK \lambda } + P \lambda[/tex]

[tex](\dfrac{T - P \lambda}{\lambda }) = \dfrac{h}{2 \lambda Q}( Q- \sqrt{\dfrac{2 \lambda K }{2}})^2 + \sqrt{\dfrac{2 h K}{\lambda}}[/tex]

Therefore:

the EOQ cost function [tex]\mathbf{g(Q)= \dfrac{h}{2 \lambda Q}( Q- \sqrt{\dfrac{2 \lambda K }{2}})^2 + \sqrt{\dfrac{2 h K}{\lambda}}}[/tex]

Answer:

Not always but sometimes

Step-by-step explanation:

The product of two irrational numbers is sometimes and not always an irrational number.

So, Let us take two Example:

Example # 1:

Let the two irrational numbers be [tex]\sf \sqrt{37} \ and \ \sqrt{2}[/tex]

So, Multiplying these will give us

=> [tex]\sf \sqrt{37} * \sqrt{2}[/tex]

=> [tex]\sf \sqrt{74}[/tex]

Which is an irrational number.

Example # 2:

Let the two irrational numbers be [tex]\sf \sqrt{2} \ and \ \sqrt{2}[/tex]

So, Multiplying them would give us:

=> [tex]\sf \sqrt{2} * \sqrt{2}[/tex]

=> [tex]\sf (\sqrt{2} )^2[/tex]

=> 2

Which is a rational number.

This means that the product of two irrational numbers is not always an irrational number but sometimes an irrational number.

Answer:

Addition Property of Equality

Step-by-step explanation:

So we had:

[tex]3x-2=7[/tex]

And then we got:

[tex]3x=9[/tex]

We did this by adding 2 to both sides of the equation. When we added 2, the left side cancelled and the right side equated to 9:

[tex](3x-2)+2=(7)+2\\3x=9[/tex]

Since we added 2 to both sides, this is an example of the addition property of equality.
