Betty bought 3 packages of chocolate cupcakes and 7 packages of vanilla cupcakes. Each package contains 24 cupcakes. Which equation is NOT a way to find c, the number of cupcakes Betty bought in all?

Answers

Answer:

The equation to find the number did cupcakes bought in all =

= 3c + 7c

= c(3 + 7)

The total number Betty bought in all = 240 cupcakes.

Step-by-step explanation:

Let the amount of cupcakes in a package be represented by c

Betty bought 3 packages of chocolate cupcakes and 7 packages of vanilla cupcakes.

The equation to find the number did cupcakes bought in all =

3 × c + 7 × c

= 3c + 7c

= c(3 + 7)

Each package contains 24 cupcakes

The total number = 3(24) + 7(24)

= 240 cupcakes.

Which of these statements best describes the relation shown in Item 1?

A- A function that is one-to-one
B-A function that is many-to-one
C-A function that is one-to-many
D-A relation that is not a function

Answers

Answer:

The relation is 'a function that is one-to-many'.

Step-by-step explanation:

From the table, we can see that element 10 i.e. y=10 in the range, corresponds to two elements i.e. x=-5, and x=5 in the domain.

In other words, the given table represents the many-to-one function as an element of the range y = 10 corresponds to more than one element in the domain.

Therefore, the relation is 'a function that is one-to-many'.

The statements that best describe the relation shown in Item 1 is one to many. Option C is correct

Functions are represented as mappings to relate the domain of the given function with the co-domain.

For instance, the function y= x + b has a domain of x and the codomain of "y"

Mappings can be one to one, where each value of the domain is a unique value in the co-domain

Many to one where one element in the domain have more than one element in the codomain

From the given table, we can see that when y = 10, the corresponding x values are 5 and -5. his shows that the codomain value (10) has more than one unique value in the domain.

Hence the statements that best describe the relation shown in Item 1 is a one to many

Your answer:​

hi

You are making  f ° h  

f(x) = 9x-5

h(x) = 2x²  

You must first calculate   h(-5)   :     so remplace  x  by -5 in h :

h(-5) = 2 (-5)² =  2* 25 = 50

then apply  f(x) to result  :   f(50) = 9 *50 -5 = 450 -5 = 445
