If 13 - x = 7, what is the value of 8x?

Write the system of equations represented by the matrix. 0 1 2 4 -2 3 6 9 1 0 1 3

Plot the points (0,6), (3,15.8), and (9.5,0) using the graphing tool, and find the function

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.
