You can put this solution on YOUR website!
your inequality is 2x - 5y < 4
\n" ); document.write( "add 5y to both sides of the inequality to get:
\n" ); document.write( "2x < 4 + 5y
\n" ); document.write( "subtract 4 from both sides of the inequality to get:
\n" ); document.write( "2x - 4 < 5y
\n" ); document.write( "divide both sides of the inequality by 5 to get:
\n" ); document.write( "2/5 * x - 4/5 < y
\n" ); document.write( "if a < b, then b > a, so your inequality becomes:
\n" ); document.write( "y > 2/5 * x - 4/5.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "another way to solve this is shown below:
\n" ); document.write( "start with 2x - 5y < 4
\n" ); document.write( "subtract 2x from both sides of the inequality to get:
\n" ); document.write( "-5y < -2x + 4
\n" ); document.write( "multiply both sides of the inequality by -1 to get:
\n" ); document.write( "5y > 2x - 4
\n" ); document.write( "multiplying both sides of an inequality by a negative number reverses the inequalit6y.
\n" ); document.write( "divide both sides of the inequaity by 5 to get:
\n" ); document.write( "y > 2/5 * x - 4/5.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "that's your inequality in slope intercept form.
\n" ); document.write( "your equation is y = 2/5 * x - 4/5.
\n" ); document.write( "any value of y greater than that satisfies your inequality.
\n" ); document.write( "for example:
\n" ); document.write( "when x = 5, y = 2/5 * x - 4/5 which becomes y = 2/5 * 5 - 4/5 which becomes y = 2 - 4/5 which becomes y = 1 and 1/5.
\n" ); document.write( "any value of y greater than 1 and 1/5 would satisfy the inequality.
\n" ); document.write( "any value of y less than or equal to 1 and 1/5 would not.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "you would graph y = 2/5 * x - 4/5.
\n" ); document.write( "you would then shade the region above that line.
\n" ); document.write( "that's your region of feasibility.
\n" ); document.write( "any value of y in the shaded region satisfies the inequality.
\n" ); document.write( "note that the value of y has to have a corresponding value of x formed by the inequality.
\n" ); document.write( "for example, assume the value of y is 25.
\n" ); document.write( "the inequality states that 25 > 2/5 * x - 4/5.
\n" ); document.write( "add 4/5 to both sides of that inequality to get 25 + 4/5 > 2/5 * x.
\n" ); document.write( "solve for x to get 64.5 > x
\n" ); document.write( "any value of x less than 64.5 would satisfy the inequality.
\n" ); document.write( "for example, if x = 64, then 25 > 2/5 * 64 - 4/5 becomes 25 > 24.8 which satisfies the inequality.
\n" ); document.write( "as long as x is less than 64.5 the inequality would be saatisfied.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the equation of y = 2/5 * x - 4/5 can be graphed as shown below.
\n" ); document.write( "the area above the graph satisfies the inequality.
\n" ); document.write( "the area below or on the graph doesn't.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "when you find a value of y above the line, you need to find the corresponding value of x.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the value of y is a coordinate point of (x,y) where the value of x is the corresponding value of x.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "this is shown in the graph below for a value of y that is equal to 30.
\n" ); document.write( "that value of y = 30 will be greater than y = 2x - 4/5 for all values of x less than or equal to 77.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the graph looks like this.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the shaded graph looks like this:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "in both graphs, you can see that any value of x less than 77 will satisfy the inequality.\r
