Solve each system algebraically using the Equal Values Method showing ALL steps! List your solution as an ordered pair ( x, y ). Make sure your graph confirms the algebraic result! a. y = x − 1 and y = −2x + 5
b. y = 3x + 2 and y = 4x + 1

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?

Someone me! if you’re smart you can solve this!

Which best describes the function on the graph? direct variation; k = −2 direct variation; k = -1/2 inverse variation; k = −2 inverse variation; k = -1/2
