What is the domain of f(x)?
{x|1 {x|1 {yl-4 {y|-4

Step-by-step explanation:

The picture of the question in the attached figure

we know that

The domain of a function is the set of all possible values of x

The domain of the line with negative slope is the interval [1,3)

The domain of the line with slope equal to zero (horizontal line ) is the interval [3,5)

so

The domain of the piece-wise function is the interval [1,5)

The value of x=1 is included in the domain set

The value of x=5 is not included in the domain set

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
