Alvin wants to know what his average paddling rate was for a canoe trip to a campsite. on the way there it took him 6 hours against a river current of 4 km/ hr. on the way back, the same distance took him 4 hours with the same 4 km/hr current. let `r` = alvin's average paddling rate.

Find the x-intercept and y-intercept of the line. 3x + 5y = −15

Asap describe the transformations required to obtain the graph of the function f(x) from the graph of the function g(x). f(x)=-5.8sin x. g(x)=sin x. a: vertical stretch by a factor of 5.8, reflection across y-axis. b: vertical stretch by a factor of 5.8,reflection across x-axis. c: horizontal stretch by a factor of 5.8, reflection across x-axis. d: horizontal stretch by a factor of 5.8 reflection across y-axis.
