please help me solve these problems. I just don't know how to do them.

CL. 3-116. Suppose 3x-ly-1- 2x-1+2y! =1. a. Find y when x = -1. b. Solve for y. CL 5-117. Graph y= - -5x +2 x - 3 a. What is the domain? b . Write an equation for the vertical asymptote. C. Write an equation for the horizontal asymptote. CL 5-118. Sam accelerates his car according to the formula v = 62, where t is the time in seconds and v is the velocity in ft/s. We wish to approximate the distance he traveled in the first two seconds. a. Sketch a velocity vs. time graph for the first two seconds. b. How can we use the graph to approximate distance? C. Jake approximated the answer by writing Distance = (0.1)[6(0.1)2 + 6(0.2)2 + 6(0.3)2 +...+ 6(2)2]. Explain what he is doing. Include as much detail as you can. d. Rewrite part (c) in sigma notation. e. Margaret approximated the answer by using midpoint rectangles. Write Margaret's sum in sigma notation if she used the same number of rectangles. traveled. f. Use the program AREA to evaluate Jake's sum and approximate the distance
