Lisa is 800800800 meters from the base of a mountain, as shown. From where she stands, she measures the angle of elevation to the peak of the mountain to be 38\degree38°38, degree. She then walks to the nearest part of the base of the mountain. Lisa measures the new angle of elevation, this time getting 49\degree49°49, degree.

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571

step-by-step explanation:

easy its decreasing

step-by-step explanation:

because its top point is at the to of the graph on the left side (atleast from the veiw i see it) now if that top point wast in the lower part of the graph it would be increasing hope this have a nice day
