The equations 2 x minus 5 y = negative 5, 11 x minus 5 y = 15, 9 x 5 y = 5, and 14 x 5 y = negative 5 are shown on the graph below. On a coordinate plane, there are 4 lines. Green line goes through (2, 1. 5) and (0. 5, negative 2). Blue line goes through (0, 1) and (0. 5, 0). Pink line goes through (negative 1, 2), and (0, negative 1). Orange line goes through (0, 1) and (2, 1. 75). Which system of equations has a solution of approximately (â€"0. 6, 0. 8)? 2 x minus 5 y = negative 5 and 14 x 5 y = negative 5 2 x minus 5 y = negative 5 and 11 x minus 5 y = 15 11 x minus 5 y = 15 and 14 x 5 y = negative 5 11 x minus 5 y = 15 and 9 x 5 y = 5.

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. a) reforestation would not benefit many species because most forest species live on the ground. b) reforestation would take the longest time to be effective because trees take several years to grow. c) biological augmentation would benefit only a few species because is is typically not very effective. d) biological augmentation would take less time to ve effective because it targets the majority of prey species.

Agraduated cylinder contains 63.0 ml of water. a piece of gold, which has a density of 19.3 g/ cm3, is added to the water and the volume goes up to 64.5 ml. calculate the mass in grams of the gold that was added to the water. explain how you got your answer.
