Aclass is trying to eliminate t from the parametric equations x=t^2+3 and y=4t. beth says that she can write t=sqrt(x-3) to eliminate the parameter. why is this wrong? she should have added 3 to x, not subtracted. she should always solve for t as a function of y. she should have taken both the positive and negative square root. she should first substitute y for t before solving.

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.

Marcus and cody both leave the park at the same time, but in opposite directions. if cody travels 6 mph faster than marcus and after 4 hours they are 64 miles apart, how fast is each traveling? solve using rare times time = distance.
