Can i please get help on my algebra class:/ it’s due the end of this month and I’m so behind

Which of the following tables represents exponential functions?

Use the elimination method to solve the systems of equations.choose the correct ordered pair. 7x+4y=39

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.
