Given the relations T and V below, use ordered pair notation to express the relation VoT.

Match these values of r with the accompanying scatterplots: - 0.385, 0.385, 0.997, - 0.767, and 1. Click the icon to view the scatterplots. Match the values of r to the scatterplots.

What is the difference between a mapping and a relation? Is every relation a mapping?

In the following problem, begin by drawing a diagram that shows the relations among the variables. -2x-2y+2z and z=x +2y, find 2. 2. w= aw dw b. dz a. C.

(a) Write a set of ordered pairs (x, y) that defines the relation.

Given this set of points (1, 10), (3.5, 7), (4, 8), (8, 4), (8, 16), (10, 6). Which points create a relation that is a direct variation?

determine the defining relation by hand a 2iii6-3

If the points (h, 0), (a, b), and (0, k) lie on a line, show that 1 + k h

Calculate: A x B, (A x B) x A, (A x B) x B, and |A x B| A = [-2,2,2]. B =[3, 1,2]
