I still need the whole question to answer it correctly .

Step-by-step explanation:

to determine a fonction a will give you an example .

(2,3) (2,3) (3,5) (8,9)

a) is f(2)

B) is f(4)

C) is f(3)

so in this case the answer would be 4 because 4 is not repeated on the first fonctions which are 2,2,3 and 8.

I don't know if your question is this case but I hope this helps.

Which property is this an example of?

Diano4ka-milaya [45]

Answer:

Inverse Property of Multiplication

Step-by-step explanation:

Inverse Property of Multiplication

The product of a number and its reciprocal is always 1.

The reciprocal of a number is 1 divided by the number.

Therefore, the reciprocal of a rational number is its inverse (swap the numerator and denominator).

For example:

$\textsf{The reciprocal of 6 is}\:\:\sf \dfrac{1}{6}$

$\implies \sf 6 \times \dfrac{1}{6}=\dfrac{6 \times 1}{6}=\dfrac{\diagup\!\!\!\!6 \times 1}{\diagup\!\!\!\!6}=1$

$\sf \textsf{The reciprocal of }\:\dfrac{3}{4} \sf \:\:is\:\:\sf \dfrac{4}{3}$

$\sf \implies \dfrac{3}{4} \times \dfrac{4}{3}=\dfrac{3 \times 4}{4 \times 3}=\dfrac{12}{12}=1$

Stacey is selling tickets to the school play. The tickets are $8 for adults and $3 for children. She sells twice as many adult t

Leona [35]

48 adult tickets and 24 children tickets were sold.

Step-by-step explanation:

Given,

Cost of one adult ticket = $8

Cost of one child ticket = $3

Total worth of sold tickets = $456

Let,

Number of adult tickets sold = x

Number of child ticket sold = y

According to given statement;

8x+3y=456 Eqn 1

x = 2y Eqn 2

Putting value of x from Eqn 1 in Eqn 2

$8(2y)+3y=456\\16y+3y=456\\19y=456$

Dividing both sides by 19

$\frac{19y}{19}=\frac{456}{19}\\y=24$

Putting y=24 in Eqn 2

$x=2(24)\\x=48$

48 adult tickets and 24 children tickets were sold.

Rob and Mike are selling cookie dough

SpyIntel [72]

The cost of one package of white chocolate chip cookie is $9 while the cost of one package of oatmeal cookie dough is $14.

<h3>What is an equation?</h3>

An equation is an expression used to show the relationship between two or more numbers and variables.

Let x represent the cost of white chocolate chip and y represent the cost of oatmeal dough, hence:

12x + 6y = 192 (1)

Also:

6x + 12y = 222 (2)

From both equations:

x = 9, y = 14

The cost of one package of white chocolate chip cookie is $9 while the cost of one package of oatmeal cookie dough is $14.
