the graphs of y = 2x - 3 and y = 2x + 7

Use the graphing method to find the number of solutions for the linear system given. 3 x + 2 y = - 3 4 3 x + 2 y = - 7 4 => two solutions or infinitely many solutions or no solution or exac..

Plot a graph for the equation y = - (2x) 3 + 2. => Graph 1 or Graph 2 or Graph 3 or Graph 4..

Graph of y = sin x - Now let us construct the graph of y = sinx from x = 0 o to 360 o . The following table is readily constructed for intervals of 30 o . Plotting the points and drawing a smooth curve through them we have the curve as sho..

As x increases from 180 o to 270 o , sinx decreases from 0 to -1 and as x increases from 270 o to 360 o , sinx increases from -1 to 0. The maximum absolute value of sin x = ..

the part of the curve from p to 2 p has the same form on the part from 1 to p . This implies that the fact tan x = tan ( p + x). The whole curve consists of an endless number of branches having the same form as the branch corresponding to the values of ..

Identify an algebraic sentence for "The sum of three times a number and seven times the same number is 20 ". Let y be the number. => 7 y = 20 + 3 y or 3 + 7 y = 20 or 3 y + 7 ..

What is the slope of the line y = - 2x 3 + 2 3 ? => - 2 3 or -2 or 3 or None of the above..

(ii) tan 2x..

Evaluate: (6 x 5 x 4 x 3 x 2 x 1) (4 x 3 x 2 x 1)(2 x 1) => 30 or 15 or 8 or 35..
