Market researchers were interested in the relationship between the price of bobbleheads and the demand of bobbleheads. Information was collected from a market research survey and was used to obtain the regression equation yy = –0.227x + 50.455, where x represents the price of a bobblehead (measured in dollars) and y is the predicted demand of bobbleheads (in units). What is the predicted demand of a bobblehead that has price of $29.99?

Agroup of students want to create a garden. they do not know the exact measurements but they propose using a variable to represent the length and width of the garden. the length of the garden is 10 feet longer than double the width. use a single variable to write algebraic expressions for both the length and width of the garden. write an algebraic expression for the area of the garden. use mathematical terms to describe this expression.
