What is the value of the expression
4x+y when x = 2 and y = 4?
2y-1

What is the vertical asymptotes of the function f(x)=x-2/x*2-3x-4

Solve each quadratic equation by factoring and using the zero product property. x^2 + 18x = 9x

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.
