True or False: Are these expressions linear? If not, why? 1) 3x + 13
2) 8/x - 4x
3) 6x^4 + 3x -9
4) -7x - 5x^0 + 12

Which expression is equivalent to 4 square root 6 divided by 3 root 2

Which value would be a solution for x in the inequality 47-4x< 7

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.
