Does the data in the table represent a direct variation or an inverse variation? write an equation to model the data in the table. (x) 1 l 2 l 5 l 10 (y) 40 l 20 l 8 l 4 a: direct variation; y= 40x b: inverse variation; y= 1/40x c: direct variation; xy= 40 d: inverse variation; xy= 1/40

Show me how you find the value of each variable and determine what the value of each variable is you i appreciate it : )

Kayla wants to find the width, ab, of a river. she walks along the edge of the river 65 ft and marks point c. then she walks 25 ft further and marks point d. she turns 90° and walks until her location, point a, and point c are collinear. she marks point e at this location, as shown. (a) can kayla conclude that δ and δ are similar? why or why not? (b) suppose de = 15 ft. what can kayla conclude about the width of the river?

Solve the formula ax+ by = c for x.
