Identify the rotation rule on a coordinate plane that verifies that triangle a(2,-1), b(4,1), c(3,3) and triangle a'(-2, 1), b'(-4,-1), c'(-3,-3) are congruent when rotated 180°. a) (x, y) → (-y, x) b) (x, y) → (-x, -y) c) (x, y) → (y, -x) d) the triangles are not congruent

List the elements of the set in roster notation. (enter empty or ∅ for the empty set.) {x | x is a letter in the word hippopotamus}

Name the most appropriate metric unit for each measurement like a length of an carrot

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.
