HELP! i can not figure this out! y=4x+1

1-for what value of x is line a parallel to line b 2-for what value of x is line a parallel to line b

Ben is three times as old as samantha, who is two years older than half of michel's age. if michel is 12. how old is ben?

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.
