Astudent solved a system of equations by elimination. the answer is not correct. describe the error made in the part of the solution shown.

Which equation represents a line that is parallel to the line whose equation is 3x-2y=7( show all work)

Consider the function f(x)=-5x+3 what is f(-2)

In each of the cases that follow, the magnitude of a vector is given along with the counterclockwise angle it makes with the +x axis. use trigonometry to find the x and y components of the vector. also, sketch each vector approximately to scale to see if your calculated answers seem reasonable. (a) 50.0 n at 60.0°, (b) 75 m/ s at 5π/ 6 rad, (c) 254 lb at 325°, (d) 69 km at 1.1π rad.
