The average price of a circus ticket from 1970 to 2000 can be modeled by the equation y = 0.32x + 28, where y represents the average price, in dollars, and x represents the number of years since 1970. What does the slope represent ?

The slope means that every year the average price of a circus ticket increases by 0.32 dollars.

Step-by-step explanation:

slope is change in y over change in x

change in average price/years

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".
