We'll be having our finals this tuesday and I need some help with the ff probs:
1.) A rectangular building whose depth is twice its frontage is divided into two parts by partition that is 30 ft from, and parallel to, the front wall. If the rear portion of the building contains 3500 ft^2, find the dimensions of the building.
2.) A man purchased some shares of stock for S1560. Later, when the price had gone up S24 per share, he sold all but 10 of them for S1520. How many shares had he bought?
3.) Draw a sketch of a line passing through the point P(-1,6) and having slope m = -2. Also sketch a line through the same point having slope m= -1/2
4.) Draw a sketch of a line passing through the equation 5x+2y-10=0 by finding the axis and y axis intercept?
**is the answer here (2,0) and (0,5)
****and oh, how do you do the find the equation that lies parallel to the given equation and the perpendicular one too...
